Crumpled cloth/paper-like black artefacts on render I'm trying to get rid of these black artefacts that looks like crumpled paper.

Is it possible that you are using a Musgrave-noise as input for a bump-node for your surfaces?
If so, you should add a &quot;Clamp&quot;-node in between, as Musgrave can deliver values outside the expected bounds.
