Texture-less/colourless .obj file when opened I have an MMD model which i exported from PMD/PMX editor in .obj format, but when I import it into blender (ver. 2.75a), it's missing it's textures, same thing happens when I open it in Keyshot, anyway to fix this/re-colour textures?
Obj files do not store color/texture information. However, it can contain a reference to an *.mtl file. 


You can check the obj file content and look if it contains a reference to an mtl file - which itself stores the colors of points/textures
Or maybe you can use another format when exporting (ply does store color information for each point for example).
