Several questions beg asking: in his ad, the vendor states... **

"Product Requirements:** Any software capable of handling .obj - 3D files"

That's a bit nebulous. I'm surprised that a product in this unpolished state would pass testing. I'd be leery of buying anything with so little to go on, just based on that statement alone. You might ask him or her which software was used to model it. Did he or she UV map it?

In the ReadMe the vendor mentions some files that come with the package:
**Files Included in the Product:

catalog.pdf
license.txt
ReadMe.txt
Tips_for_Bryce.pdf
tips_for_use.pdf**

Do any of these contain any information on how to apply the textures for those fences in Poser?
