We are currently updating all our 3D models to new PBR maps/rendering.
PBR is Physically Based Rendering . We use texture map for diffuse (albedo), reflexion, etc. …
So now NO MATERIALS are used. With PBR textures, all our models will be compatible with your 3D application (Blender, 3DS max, Maya, etc. …)
We use Cinema 4D for modelling, but will export .FBX models each time, that is 100 readable and compatible with other softwares.
