Having trouble finding a solution to the problem in the pic below. If you see the two speckled split rings, they are using the same copper material as the large loop in-between the two magnet poles. No matter what I do I can’t seem to get them to render properly. I’ve tried flipping normals and that dosn’t seem to work. Even when I change the material to one of the others in the scene it still has the same speckled effect. I’ve checked and there are no textures assigned. It also seems to appear on a few faces on the main axle support. At first I thought this bit was shadows, maybe due to the AO being used but it doesn’t seem to be that.
The only difference with these parts of the modelling is that they have had a fair bit of editing done in edit mode.
I am a novice and this is my first project.
Thanks for any help anyone can give.
