It appears that LOD1+ of Cubic voxels are only displaying a default material, while marching cubes is showing the correct ones on all LODs (see image1)! some higher lod voxels are getting the other index though (image2). issue appears with all material modes.
Phyronnaz: this is because cubic doesn't find the exact surface voxels on higher LOD
So the displayed material is not exactly the one on the surface
