I'm new to blender, so apologies if this is a fairly beginner question. I followed this tutorial ( https://youtu.be/vS1eDp3az5Y ) to make a crescent moon shape using bezier curves. Now, though, I want to UV Map an image texture on top of it, but I can't because there are no real verticies, it's just two bezier curves. Is there any way I can unwrap something like this?
In recent version of Blender, you can use an automatically generated UV Map. You can modify the map's coordinates in the Properties Editor's Curve Properties tab; in the Texture Space panel:
Here is an example material where I just used the automatic map and a generated UV grid image:
and here is sample curve:
You can read more about Texture Space in the manual.
