How I can export scene from roblox (parts, characters) and keep texture color?

Hi guys. Today I got tired with scripting and have decided to make thumbnails for my game. But, as usual, I run into some problems. Now, it’s problem of exporting map.
When I export it, I receive parts with colored vertex, and greyscale material textures. Is there any way to apply vertex color to texture, or export colored textures?
