Alekssander, if they originate from image file textures, and then have been saved to Vue .mat files, yes, you need to include them with the files. If they are just procedural materials, then you don't have to include anything. If they are Vue 4 materials/VOB's plaes note that when you upload them since Vue 3 and Vue 2 people won't be able to use them. Also, the path matters when saving a texture as a .mat file. So if your textures are in a directory such as: F:/...Vue4/Bitmaps/Alekssander/carpets/texname.jpg, that's where Vue will always look for them. However, it seems as though if you place the textures in the same folder as the .VOB models are in, the path doesn't matter, and Vue finds them. At least, I think that works. What I tend to do is to keep my textures in the same folder as the models, just to make things simpler. But that's just what works for me.
