HI,\r\n\r\nI have attached an image of a simple poly object that I created (I took a cube poly and did a boolean operation for the hole using another cube that I had modified). My question is how to smooth the inner surface for rendering.\r\n\r\nIf I add more subdivisions and move the points to create a rounder surface I still get flat edges regardless of how close the points are. I have tried smooth and proxy smooth, which just seem to distort the object (could be using them wrong). I have also adjusted rendering options to Production for anti-aliasing and increased passes ? \r\n\r\nAnyway, what's the best way to smooth this top section out please ?????\r\n\r\nCheers,\r\n\r\n\r\nDon.
