How can I make the background of this stylized bush transparent?

[Aotrou (Shawn)]

Instead of relying on partial transparency, use SurfaceAppearance objects so it shows properly:

Texture clipping through itself. Help?

These are known as depth sorting errors. Using a SurfaceAppearance object inside your MeshPart will likely fix the issue. If you’re using a texture, add the TextureId to the ColorMap property, and setting the SurfaceAppearance’s AlphaMode to Transparency.
