+# 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.
