Alright that makes sense I have since sent in a request to the irender help team. Will see what they say.

Hi All

new to scene, Im playing around with rendering these days in sketchup and Im using a trial version of Irender, which seems to be doing very well for me. Its very user friendly and seems to produce half decent renders.

My question is I downloaded a free zip file from Arroway textures, which contain 3 files. Diffuse, bump, and specular. I read a little on how one is for reflection and other for depth. I get that concept, however my question is how to I bring all 3 together into my sketchup model to apply to the surface? I currently just go to materials and create new material and search for the main jpg. and bring it in, scale it up and attach. But I would like to have all 3 together so I can achieve more depth and proper reflection.

I hope Im asking this correctly.

Thanks
