What app are you using? Somebody here will probably know if it supports .MTLs. Also a .mtl only stores solid colors, image textures and surface property values. If there's not any nodes hooked up to a image texture you won't get any in the .MTL. You also have to have the bump channel hooked to a bump image texture for bump maps to be included. P5's "math" textures and displacements are an internal part of Poser and can't be exported. HTH; Dan
