Unity shader examples
Use these with geometry you export from Open Brush and import into Unity. However, you should prefer to use the Open Brush Toolkit, which comes with all the Open Brush shaders.

_MainTex ("Base (RGBA)", 2D) = "white" {}
_BumpMap ("Normalmap", 2D) = "bump" {}
_Cutoff ("Alpha cutoff", Range(0,1)) = 0.5
