I found one very old post about this, it seems all unbiased renderers suffer from showing wrong shading of some triangles of low poly objects.
but I have a high poly object here, and as soon as I apply bump mapping (even just 1 percent) I get following result. anyone knows how to deal with this?
smoothing is at 60%, I tried other values, and I hit the recalc button, so it is not that.
tnx

I had a similar issue in maya, I solved it using "unlock normals" and "set to face".

[wimver]

that is probably a Maya thing, I use plain imported obj files in studio.
but thanks for replying!

What does the bump map look like? Because if it's high contrast and high frequency, even 1% might be too much. You could try lowering the nr of repeats and see.

Judging from the picture it looks like the normals are fked up.

Maybe a normal map without the 'n' option set in bump?

[wimver]

the bumpmap is a 500x500px noise file, this is a part of it:



the repeat is 3 times in H, 20 times in V direction

What do you mean by a normal map without the N option set in bump? is this a studio option?

tnx

OK, lowering the repeat seems to do the trick. I elongated the noise in photoshop, to get the same effect.

thanks all, especially Mihai!
