When I import a some OBJs the triangle's normals look 'rough.' I have enabled smooth but no affect.

I'm sure this topic has been discussed before so any redirections will be helpfull.

I have attached an example screen.

Looks like you have normals that are facing the wrong direction. Make sure that they are all pointing outward.

Maybe a scaling problem ?

And the correct answer goes to......... Zay!

The render when model is scaled down by 90%.

Cheers!

Looks like you still have those dodgy normals.

It's a low poly version - if I divide it it'll look neater.

I didn't intend to be rude, infact my only initial thoughts were that it was a normal problem aswell but if I unified, flipped, or made any changes to normals the results were the same.

When I imported the model into my 3d app it was massive (10x standard grid size) thus the problem.

Try playing with the ray epsilon, to avoid shadow artifacts at the terminators.
