Does an Obj important contain UV mapped textures? I am almost a total beginner with blender. I purchased a model off of https://www.turbosquid.com/3d-models/maya-human-eye/818788. which came with a .obj file, a .mb files and some .jpg textures. On the website it says its already been fully textured and UVmapped. But when I import the .obj into blender, it does not appear to have any textures applied (and when I switch to rendered view it's just black). 

I also tried loading the .mb file into maya and I see this green blob, though it does appear to contain textures and material properties. 


Given what you see, does the .obj file not have textures and is there no way to work with in blender?
No, a .obj file does not contain textures. This is not a problem with Blender, but just an inherent thing to .objs. It stores the mesh information and actually includes UVs, but not the textures. You will have to import textures separately just like with any other application that uses .objs.
