Rendered with VRay 1.5
Main product format is 3DMax. Max archive includes:
1) Titan.max - clean scene with textures applied but no shader setup. You can use this scene as a base for further work with any render engine you use
2) Titan_vr.max - scene with VRay materials, shaders and scene setup to get the same renders as on thumbnails
Please be advised that only VRay version of Max file has scene setup, shaders and textures applied. All other files and formats have only textures applied. They do not have any shader or scene setup, just textures.
You can get textures either from Max archive or from separate 'textures.rar' archive
