By the way, I made a new texture for the large back panel, and again with a 'normal render' of a couple of extruded cilinders as the 'Deeper' bump texture, this time straight. On that normal bump, I put a little distress via a subtracted texture map. That has it's effect on the render time, but it is easy to make an interesting looking construction fast this way. I started an 'everything to the max' render at 2400 px last night, but I cancelled it, as you can see. Too much time, for an in-between thing. All parts are moddelled now, I will work on it today, probably.
