Using 4.25.3 and some LODS applied to my foliage are not displaying correctly in ShaderComplexity mode and MeshLODColoration mode. (Tested in ShaderModel5 and iOS Preview Rendering Levels)
What better than some images to show it:
My foliage use 3-materials/3-LODs and all 3 materials inherit from the same parent/master material.
The LOD0 material works at all LOD levels.
But the LOD1 and LOD2 materials do not show their complexity in ShaderComplexity mode and they don’t even show up as transitions in the MeshLodColoration mode. They are shown in black color.
