+## 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
+

+
+## 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.
