We just launched this 3d modeling & materials resource, teaching people how to generate photo-realistic models for rendering.
https://tech.wayfair.com/wayfair-3d-modeling/
We cover the whole process: modeling, UVs, materials, lighting, & rendering. More on the way too.
Our goal is to make 3d modeling easier for the makers of furniture & home goods, which we can use together to make better imagery, VR, AR, etc.

Even if it's not strictly game-related, hopefully this is useful to artists here!
