Unless I'm misremembering Blender doesn't have backface culling on by default, so that's probably why it looks fine there.

Also there's a lot of ways to accidentally mess up the normals, to make it easier to check you can turn on the "Face Orientation" overlay.

To avoid the overhead of Triplanar mapping you can also use "Correct Face Attributes" in Blender for a similar effect. It doesn't work on everything, but it'll "extrapolate" out your UVs.

Plus it'll import straight into Godot if you use a gltf/glb file. (.blend is inconsistent in my experience)

This is so cool! Are you planning to put the code up anywhere so people can peek at it? Cause this seems so nice for putting UI in 3D, which is something I've wanted for absolute AGES. AND keep failing at. Even tried recreating it, and got *something* (it was worse a bit ago so progress)

Well #introduction time I guess. I'm Eroax (or EroAxee depending).

I'm a self taught game dev and 3D artist who uses #Blender3d for ABSOLUTELY everything. For example, did you know Blender has a video editor ?

I'm mostly focusing on learning animation + working on streaming integrations.
