Definitely props and textures. - or articulated figures with MAT pose files to apply textures and materials. Speaking of materials, please be sure and specify Material groups by name (not just material_1, material_2 etc) and make as many materials as the prop requires for realistic rendering and flexibility. Also UV mapping is very important. Please don't just send out a beautiful prop that can't be realistically textured (unless it's a freebie). Thanks
