papsphilip Posted February 28, 2021 Share Posted February 28, 2021 after the subdivide node you can see these star shaped polygons appear and as a result produce render artifacts. How can i fix this? subdivision is not really needed in the center of the circular polygon but mostly on its edges so that they get rounded along with the rim.

ryew Posted February 28, 2021 Share Posted February 28, 2021 As a quick and dirty solution, you can just make a group for the rim geometry and use that to limit what the Subdivide node affects 1 Quote Link to comment Share on other sites More sharing options...
DaJuice Posted March 2, 2021 Share Posted March 2, 2021 The star-shaped subdivision is the expected result with your topology. To get rid of the visible shading "artifacts", select the large ngon in the center, append a PolyExtrude SOP and increase the Inset parameter a little bit. Increase the divisions to 2 as well. That will provide a sort of anchor where the sides meets the face and still give you rounding along those edge. Quote Link to comment Share on other sites More sharing options...
papsphilip Posted March 3, 2021 Author Share Posted March 3, 2021 thank you! i ended up bricking up the ngon with a divide node and the artifacts are gone. Quote Link to comment Share on other sites More sharing options...
