Please, I need some help on how to import  .rsr extension file along with its material into poser. I'm totally new to poser and I know this is probably a beginner's question but please don't be annoyed with it.

Also,  when  I model an object in the free open source 3D software BLENDER and import to poser, the object does not import with its material. The material is saved seperately as an .MTL file but I do not know how to attach this .mtl file to the imported .obj file in  poser.

I use poser 7.

Thank you.
