I have increased pixel samples to 9 and the rendering is extremely slow. Moreover some of those dirts are still there. Do you know any more efficient way of dealing with it?
And one more question. Why there are white stripes across crystal? How can I remove them?

Hi mikolaj,
Without knowing what geometry you're using, or what lighting & render settings, it's difficult to give assistance.
But, you could check the following:
1) Your normals - perhaps add a facet node at the end of your geometry network and select the ‘Post-compute Normals’ option?
2) The ‘raytracing bias’ settings on the Mantra ROP > rendering > shading > tab. If that's set too high for your scene scale, there can be artifacts in renders.
3) And as for the white lines - without knowing your scene setup, it's hard to say, but it may be normals related too.
Hope this is of some help,
Matt.
