There are two 3d models from the sketchfab. I'm trying to convert them to voxels using an online voxelizer. In the first case, when I use Lightning McQueen, everything is fine, he prompts me to add a texture. In the second case, when I use Doc Hudson, it does not offer to add a texture and writes that several textures need to be combined into one. I can not figure out where and how exactly to do this in blender. Please tell me. Thank you
