Eitht Posted April 9, 2011 Share Posted April 9, 2011 G'morning, encountered these render artifacts while using dent_fractal. At first i thought the problem lies in my rock geo, not until i unplugged the displacement shader and all of them were gone. Low or high values for the displacement didn't make them go away. I turned to Micropoly instead of PBR which miraculously gave me a much better result with tiny black spots still haunting me. Really puzzled what's happening here, somebody please. =_= eitht. antiAliasedNoiseVOPSOP.hipnc Quote Link to comment Share on other sites More sharing options...
DanBode Posted April 9, 2011 Share Posted April 9, 2011 This is a classic displacement bounds issue. What's happening is that your displacement shader is pushing geometry beyond the bounds that mantra has defined. To fix this drop a Properties SHOP, connect it to the suboutput in your material, and add the displacement bound rendering property. A value of .1 seems to work in this case.
