Hello !

I don’t understand how can I use away3d.materials.utils.MultipleMaterials with a cube.

The only solution it’s to create a custom Cube class with 6 planes ?

The MultipleMaterials class is not actually used anywhere in the engine, and cannot be used with a mesh and CubeGeometry to automatically map different materials to different sides of the cubes. To be honest I think it’s just legacy.

If you want different materials on all sides of a cube you have to create six planes, correct. If you just want different textures, lay them out into a single texture as described in the documentation for the CubeGeometry.tile6 property, and set that property to true. Then use that texture in a texture material for the cube.

Thank you for your answer !
