So I am working with a node shader where I create an input block vector2 and assign uv3 to it.
Example: Babylon.js Playground
The problem I have having is that while it seems to work in the playground when I try it in my code it the material won’t build.
What is interesting is that if I use “uv” or “uv2” it works just fine. But it seems if I use any of the others like “uv3, uv4, …” the material fails to build. I know its a bit of a long shot but any ideas why “uv” and “uv2” work but the others don’t?
