+# SmartShape2D - FAQ
+
+<!-- TODO: Outdated. -->
+
+## Why aren't my textures repeating?
+
+If your textures aren't repeating and look something like this:
+
+![Non-Repeating-Texture-IMG](./imgs/faq-texture-repeat.png)
+
+The issue is most likely that you need to set the texture's import options in Godot:
+
+![Import-Texture-Settings](./imgs/faq-texture-repeat-import.png)
+
+## Why isn't my shape updaing when I change the Light Mask?
+
+Each shape is currently rendered by multiple-subnodes (Children Node2Ds).
+Their owner isn't set, making them invisible in the editor (unless you have debug mode on).
+
+Unfortunately, there is no accessible signal when changing the Light Mask setting in editor.
+That means changing the Light Mask setting in editor won't trigger the children nodes to change THIER Light Mask
+
+The Shape nodes CAN update their children's light mask, they just need to be triggered to do it manually.
+If you update the shape in any way, the shape will update its children's light mask.
+
+When playing the game, the render Node children are regenerated, ensuring that the light mask will be set
+correctly.
+
+The actual shape has set\_light\_mask overloaded, so changing the light\_mask in code should work without issue
+
+If you need to manually tell the shape to update its rendering, call the set\_as\_dirty() method
+
+If anyone has any insights on this issue, please feel free to open an issue on this subject
+and let us know how we might be able to fix it
+
+## Why does changing the width look so ugly?
+
+Changing the width of the quads generally looks best with welding turned off.
+
+If welding is on, you can still change the width of the quads, but you may need to play with it a bit.
+It's best that you change the width gradually in small increments instead of sharply.
+Sharply changing the width will result in odd looking shapes.

+# Using SmartShape2D with Godot 4
+
+Godot 4 moved `repeat` for textures as an import option to a per-node option. On how to make textures repeat and
+set normal maps see [section below.](#repeating-textures-and-normal-textures-with-canvastexture)
+
+By default, **shape resources are shared** when the shape is copy-pasted. Editing points will edit every copy of that shape.
+To make point geometry unique, press **"Make Unique"** property button in Geometry property group in the inspector:
+
+![Making Shape Geometry Unique](imgs/godot4-make-points-unique.png)
+
+## Repeating Textures and Normal Textures with CanvasTexture
+
+CanvasItem, the base class of Node2D has a Texture section with `repeat`.  If you aren't using a normal, you can set it here.
+By default, this setting is inherited by children nodes so you could set it on a parent node (assuming all the children need
+repeating textures or it's easier to disable for a few specific nodes than turn it on for most).
+
+![Creating CanvasTexture](imgs/canvas-item-repeat.png)
+
+Normal textures are no longer set in a material resource.
+
+To set normal textures, you can create a `CanvasTexture` resource in the inspector on any property, that allows setting a `Texture2D`.
+
+![Creating CanvasTexture](imgs/godot4-create-texture-res.png)
+
+`CanvasTexture` allows you to assign diffuse texture and normal map texture, as well as set textures to `repeat`:
+
+![Assigning Texture, Normal Map and Setting Repeat flag](img/../imgs/godot4-assign-normal-tex.png)
+
+## Converting Projects from Godot 3.x
+
+Scene files with shapes saved in Godot 3.x should load in Godot 4 project. However, you may encounter some issues. Here is a list of expected problems:
+1. Textures are looking weird, not repeated.
+2. Normal textures are not used.
+
+Please read the section on [how to set repeat and use normal textures in Godot 4](#repeating-textures-and-normal-textures-with-canvastexture).
+
+## Removed Features
+
+- The Godot 4 version of this addon does not support 1.x RMSmartShape2D nodes anymore.
+- SS2D_Shape_Meta node was removed, since its functionality is available  copy-pasted shapes by default.

+# Normals
+
+## Default Normals
+
+Even if you assign normal textures to your Edge Material, the normals will look wrong.
+
+For example, consider the following image:
+
+![Normals Wrong](./imgs/NormalWrong.png)
+
+The normals in the image clearly don't line up with where the light is actually coming from.
+
+## Encoding Normal data in the canvas_item Vertex Shader Color Parameter
+
+As SmartShape renders the edges, the textures and their normal textures are also rotated.
+This will result in incorrect normals.
+To solve this, we can use a shader to correctly calculate the normals.
+
+The tricky part lies in how few ways there are to pass data to a canvasItem shader on a per-vertex basis.
+See here for the full list:
+https://docs.godotengine.org/en/stable/tutorials/shading/shading_reference/canvas_item_shader.html#doc-canvas-item-shader
+
+Fortunately, the COLOR parameter can be used for this purpose.
+The COLOR ENCODING paramter of an Edge Material can be used to choose what data is encoded in the
+Vertex Shader's Color Parameter.
+
+If we set the COLOR ENCODING value to "Normals", we get this:
+
+![Normals wrong with weird diffuse colors](./imgs/NormalColors.png)
+
+Ok, so now the normals still look wrong, but the colors look wrong too. Great.
+
+There is one final step before our normals will be correct. We need to decode the normal data in a shader.
+
+
+## Writing a Shader
+
+You'll want to assign a new shader to the Edge Material's material property.
+This shader will determine how each edge is rendered.
+
+Here's a sample shader to decode our normal data and set our actual color to that of our diffuse texture:
+
+```glsl
+shader_type canvas_item;
+
+varying mat2 NORMAL_MATRIX;
+
+void vertex() {
+	NORMAL_MATRIX = mat2(COLOR.rg, COLOR.ba)*2.0 - mat2(vec2(1.0), vec2(1.0));
+}
+
+void fragment() {
+	NORMAL.xy = NORMAL_MATRIX*NORMAL.xy;
+	COLOR = texture(TEXTURE, UV);
+}
+```
+
+After assigning this shader the the Edge Material's material property, our normals finally look right:
+
+![Normals Correct](./imgs/NormalCorrect.png)

+# SmartShape2D - QuickStart
+---
+![Finished Image](./imgs/Inpsector-EdgeMaterialsNormalRange.png)
+
+If you feel like your workflow with SmartShape2D is a little bit slow, try reading [Controls and Hotkeys](./Controls.md). The hotkeys may help you work with the tool more effectively.
+
+## Basic understanding
+SmartShapes work similarly to [tilesets](https://docs.godotengine.org/en/latest/tutorials/2d/using_tilesets.html) but are not bound to a grid. They can be used to create polygons and even organic shapes. This allows for level design akin to [Rayman Legends](https://youtu.be/WFu1utKAZ18?si=_33TaErpHSh-r732&t=916) (based on the UbiArt Framework).
+
+Each SmartShape is made up of multiple textures that are responsible for rendering different aspects like corners or edges:
+
+![Texture Breakdown](./imgs/smartshape_textures_breakdown.png)
+
+## Creating a Shape
+
+<!-- TODO: Outdated, including screenshots. -->
+
+- First, instance a node of either:
+  - SS2D_Shape_Open
+  - **SS2D_Shape_Closed**
+    - **We'll use a closed shape for this Quickstart demo**
+- SS2D_Shape_Base cannot be instanced directly
+- SS2D_Shape_Anchor is a node that attaches to a shape
+- The following Nodes are legacy nodes and are deprecated:
+  - RMSmartShape2D
+  - RMSmartShape2DAnchor
+
+![Nodes](./imgs/NewNode-SS2D_Nodes.png)
+
+## Editing the Shape
+
+- After creating the shape node, make sure it's selected and the toolbar appears and is in Point Edit mode
+  - ![Toolbar Default State](./imgs/Toolbar-PointEdit.png)
+- Hold ALT and Left Click on the viewport to add points
+  - If this is a closed shape, the polygon will close after adding the 3rd point
+- You should now have a shape consisting of a few points and lines:
+
+![Toolbar Default State](./imgs/ShapeClosed-Untextured.png)
+
+## Setting the Fill Texture of the Shape (Closed Shape only)
+
+- To give it some life, we'll want to edit the "Shape Material" in the Inspector
+- Under "Shape Material" Expand "Fill Textures" and you'll see an empty array
+- Set the Array's size to '1'
+- Assign a texture to the newly created slot in the array
+- After assigning the shape should now have a valid texture
+  - If nothing happens after setting the texture, try to force the shape to update by adjusting one of the points
+- **Note that "Fill Textures" does not affect open shapes at all**
+- If you want to add a normal_texture, you would add it using the "Fill Texture Normals" property
+
+![Fill Texture Set](./imgs/ShapeClosed-FillTextured.png)
+
+## Texturing the Edges
+
+- This where the rubber hits the road, the real meat of the tool
+- Under "Shape Material" add an element to the "Edge Meta Materials" property
+  - Shape Material -> Edge Meta Materials
+- Set the resource of the newly created element to "SS2D_Material_Edge_Metadata"
+  - Unfortunately, due to Godot limitations, every avaiable resource will offered to you instead of the one you want
+  - The options are alphabetized though, which helps in finding the resource you want
+- Expand the first element of the "Edge Meta Materials" that you just set
+  - Shape Material -> Edge Meta Materials -> element 1
+- Set the value of the "Edge Material" property to a new resource of type "SS2D_Material_Edge"
+  - Shape Material -> Edge Meta Materials -> element 1 -> Edge Material
+- Expand "Edge Material" that you just set
+- Add an element to "Textures" and assign the texture to one that you want to use as an edge
+- The shape's edges should now update using the texture you set
+  - If nothing happens after setting the texture, try to force the shape to update by adjusting one of the points
+- If you want to add a normal_texture, you would add it using the "Texture Normals" property
+- Godot should now look something like this:
+
+![Inspector](./imgs/Inpsector-EdgeMaterial.png)
+
+### Corners
+
+- If your shape has sharp 90-degree corners, the texture can look a bit warped in those places
+- You can specify a unique texture to use for inner and outer corners for each Edge Material
+- The following Edge Material properties are used for corners
+  - Textures Corner Inner
+  - Texture Normals Corner Inner
+  - Textures Corner Outer
+  - Texture Normals Corner Outer
+- See how the addition of outer corner textures improves the square created earlier
+
+![Inspector](./imgs/Inpsector-EdgeMaterialCornerOuter.png)
+
+### Multiple Edge Materials in One Edge
+
+- You can add as many Edge Meta Materials as you want to a Shape Material, each with their own Edge Material
+- For instance, you can add an additional egde with a rock texture (and its own set of corner textures) and have it render behind the grass
+  - To have it render behind the grass, Set the Z index of the meta material
+
+![Inspector](./imgs/Inpsector-EdgeMaterials2.png)
+
+### Normal Range
+
+- Each Meta material has a Normal Range
+- The Normal Range indicates when a texture should be rendered
+  - If the normal range is 0 - 360 or 0 - 0, then any angle is considered in range and the edge will always render
+  - Angle "0" is Facing directly Right
+  - Angle "90" is Facing directly Up
+  - Angle "180" is Facing directly Left
+  - Angle "270" is Facing directly Down
+
+- If you wanted to, for example:
+  - Have rocks display on the bottom part of the shape only
+  - Have grass display on the sides and top of the shape only
+- You could:
+  - Set the grass Normal Range to 0 - 180
+  - Set the rock Normal Range to 181 - 359
+
+![Inspector](./imgs/Inpsector-EdgeMaterialsNormalRange.png)
+
+### Material Overrides
+
+- Using Material Overrides will allow you to change how specific edges are rendered
+- For Example, to prevent the left edge from rendering, we'll do the following:
+  - Select the edge edit button from the toolbar ![](./imgs/icon_edge.png)
+  - Right Click the left edge of the shape
+  - Press the "Material Override" Button
+  - Uncheck the "Render" Checkbox
+
+![Edge NoRender](./imgs/EdgeEdit-NoRender.png)
+
+- You can use material overrrides to also specify a specific material for a single edge
+- For example, Checking Render and choosing the "Rock" Edge Material will cause the edge to render as rocks, even though the NormalRange configuration would otherwise have it render as grass
+
+### Multiple Textures
+
+- If more than one texture is specified for an Edge Material, you can specify which texture should be used
+- Enter Point Edit mode, mouseover a point, and scroll up or down to change the texture index
+
+## Anchoring Nodes to the Shape
+
+- To anchor nodes directly to the SmartShape2D node, use SmartSahpeAnchor2D
+- You can then make nodes children to the anchor

+## Shape Materials
+
+Shape materials provide all the texture and collision information needed by the SmartShape nodes.
+Once a shape material is defined, it can be easily reused by any number of SmartShape2D nodes.
+
+- Edge Meta Materials
+  - An array of resources of type SS2D_Material_Edge_Metadata
+- Fill Textures
+  - Used as the texture for the inside of the polygon for Closed Shapes
+  - Currently, only the first texture can be used, multiple textures may be supported at a later date
+- Normal Textures
+  - In Godot 4, you can set normal textures with `CanvasTexture` resource.
+- Fill Texture Z Index
+  - Each Edge Meta Material has a ZIndex indicating which edges are drawn first
+  - This sets the ZIndex for the fill texture
+  - This allows the user to draw the fill texture in front of some edges or behind others
+- Fill Mesh Offset
+  - The Offset of the Fill Mesh
+  - Can be used to grow / shrink the fill mesh
+- Render Offset
+  - Every edge in the shape will be offset by this amount
+- Weld
+  - Whether or not to weld the last quad of an edge with the first quad of the next edge
+
+## Edge Meta Material
+
+An Edge Meta Material doesn't contain the actual textures used to render an edge like **Edge Material** does.
+Instead, this resource contains a single **Edge Material** and describes how and when to render the edge.
+
+- Normal Range
+  - The angles at which an edge is allowed to be rendered
+- Weld
+  - Whether or not to weld the quads in this edge
+- Taper Sharp Corners
+  - Edge vertices sharper than 90° that aren't rendered as corners, will be tapered and not welded
+  - Will not work properly on shapes with curves
+- Render
+  - Whether or not this edge is visible
+- Z Index
+  - Dictates the order in which edges are drawn
+- Offset
+  - Offset of the edge
+  - Can use a positive or negative value to draw the edges closer or further from the shape
+
+## Normal Range
+
+The Normal Range indicates when a texture should be rendered.
+Each shape will compare the Surface Normal of an edge to the Normal Range in each Edge Meta Material.
+If the edge's Normal is inside a Meta Material's Normal Range, the Meta Material's Edge Material is rendered.
+
+![NormalRangeVisual](./imgs/AngleExplaination.png)
+
+- A Normal Range is specified in Degrees
+  - If the normal range is 0 - 360 or 0 - 0, any angle is considered in range and the edge will always render
+  - Angle "0" is Facing directly Right
+  - Angle "90" is Facing directly Up
+  - Angle "180" is Facing directly Left
+  - Angle "270" is Facing directly Down
+
+## Edge Material
+
+The actual textures used to define an edge
+
+### Textures
+
+- The primary textures used for the edge
+- At least one texture must be defined
+- Example: ![Grass](./imgs/grass.png)
+
+### Taper Textures
+
+These textures will be used as the first or last quad in an edge.
+They're named "Taper Textures" because the purpose is to show the edge "tapering off"
+- Textures_Taper_Left is the first quad in an edge
+  - Example: ![Grass Taper Left](./imgs/grass-taper-left.png)
+- Textures_Taper_Right is the final quad in an edge
+  - Example: ![Grass Taper Right](./imgs/grass-taper-right.png)
+
+### Corner Textures
+
+These textures will be used when the edge forms a sharp corner (80 degrees - 100 degrees)
+These are used because corners can look warped when using only regular textures
+- Texture_Corner_Inner is used when the corner forms an inner corner
+  - Example: ![Grass Corner Inner](./imgs/grass-corner-inner.png)
+- Texture_Corner_Outer is used when the corner forms an outer angle
+  - Example: ![Grass Corner Outer](./imgs/grass-corner-outer.png)
+
+### Normal Texture and Repeat
+
+To use normal textures, you can create a `CanvasTexture` resource in the inspector on any property,
+that allows to set a texture. There you can assign your texture and your normal texture, as well as set
+those to `repeat`.
+
+### Repeat Textures
+
+See previous section.
+
+### Fit Mode
+
+Most likely, the textures you use will not *perfectly* fit the polygon.
+This setting allows you to determine how SmartShape will rectify this.
+
+Differt options may look better or worse depending on the art-style.
+
+- Sqush and Stretch
+  - Texture will be mutated
+  - Either slightly squished or stretched to fit the polygon
+- Crop
+  - Texture will not be mutated
+  - Texture will simply be cropped when changing from one texture to the next

+# SmartShape2D - Shapes
+
+Each shape consists of a set of points. You can directly edit either the points or the edges between the points in the viewport.
+
+Shapes are configured to use a [Shape Material](./Resources.md#ShapeMaterial) which determines how the shape is rendered.
+
+A shape can be open or closed. Each new shape starts open. To close a shape, simply add a point on top of the first one.
+
+
+## Properties
+
+> 🛈 Most properties now have documentation comments.
+
+<!-- TODO: this is incomplete - not all properties are here -->
+
+### Editor Debug
+
+- Will show the bounding box for each quad in the mesh of edges.
+- Can be helpful to illustrate why a shape doesn't look the way you expect.
+
+### Flip Edges
+
+- Will flip the edges of the shape (invert y).
+
+### Render Edges
+
+- Whether or not the edges of the shape should be rendered.
+
+### Collision Size
+
+- Size of the collision shape.
+
+### Collision Offset
+
+- Offset of where the collision shape starts and ends.
+- A **positive** value offsets the collision shape **outwards**.
+- A **negative** value offsets the collision shape **inwards**.
+
+### Tessellation Stages
+
+- Number of stages in the curve tessellation process (Uses Curve2D Internally).
+- First Param in Curve2D.tessellate.
+- See [Curve2D Documentation](https://docs.godotengine.org/en/3.2/classes/class_curve2d.html#class-curve2d-method-tessellate).
+
+### Tessellation Tolerence
+
+- Tolerence Degrees in the curve tessellation process (Uses Curve2D Internally).
+- Second Param in Curve2D.tessellate.
+- See [Curve2D Documentation](https://docs.godotengine.org/en/3.2/classes/class_curve2d.html#class-curve2d-method-tessellate).
+
+### Collision Generation Method
+
+- Controls which method should be used to generate the collision shape.
+- See also in-engine documentation.
+
+### Collision Update Mode
+
+- Controls when to update collisions.
+- See also in-engine documentation.
+
+### Curve Bake Interval
+
+- Bake interval value for Curve2D.
+- See [Curve2D Documentation](https://docs.godotengine.org/en/3.2/classes/class_curve2d.html#class-curve2d-property-bake-interval).
+
+### Collision Polygon Node Path
+
+- The path to the CollisionShape that the SmartShape will use for collision.
+- Is Autoset when pressing the generate collision button.
+
+### Shape Material
+
+- The material that this shape will use to render itself.
+- For backwards compatibility `fill_texture_z_index` defaults to `-10`. Set this to `0` and enable `fill_texture_show_behind_parent` in order to preserve Godot's normal z-sorting when layering with other nodes.
+
+### Points
+
+- **There is no need to edit this property by hand, but you can if you'd like.**
+- Contains all of the points and meta-data for the points contained in this shape.
+- This data structure is updated as you manipulate the shape.
+
+### Material Overrides
+
+- **There is no need to edit this property by hand, but you can if you'd like.**
+- When an edge is given a "Material Override" the data for that edge is stored here.
+- This data structure is updated as you manipulate the shape.

+
+## Edge Mode
+
+- In this mode you can Move Eges and choose how specific edges are rendered
+- To **Move** an Edge, Left Click and Drag the Edge
+- To **Change an Edges Rendering**, right click the edge and press "**Material Override**"
+![EdgeData Popup](./imgs/EdgeEdit-MaterialOverride.png)
+
+- This popup allows you to **change how edges are rendered**
+  - **Render** will toggle whether or not this edge will be drawn with Edge Materials
+  - **Set Material** allows you to choose a specific Edge Material to use to render this edge
+
+## Origin Set
+
+- This tool allows you to set the origin of any SmartShape
+- To **Set the Origin** Left Click anywhere on the viewport
+
+## Generate Collision
+
+- If you want your shape to have collision, press this button to autogenerate the collision nodes
+- The shape will be made a child of a newly created **StaticBody2D**
+- A sibling node, **CollisionPolygon2D** will also be created and added to the SceneTree
+  - The "Collision Polygon" parameter of the Shape will be set to this sibling **CollisionPolygon2D**
+
+## Snapping
+
+When Moving / Adding points, snapping will cause the positions of the points to snap to the grid. This works the same as Godot's built-in snapping.
+You can have snapping either use Global Space, or space relative to the shape's origin.
