Yeah, I know the reflections are too much. I too have worked with galvanised metal... well guarded it anyway. But I didn't see that until the render was done and I only posted this to show the textures... in position so to speak. Mind you my galvanised were little round discs or small casings. About the bump, I'm using the same pic but with more contrast etc, but only at about 3.3 or something. Up to 10? or up ten more from 3 to 13? I'll give it a try anyway. If you look at the top left of the pic there are some very distracting reflections - but I was hoping no one would notice until I'd got them fixed... This render both started and completed while the longy was still struggling along... weird.
