Hi Vesa, To render the scenes I am currently dealing with, the improvement would need to be in the region of 7 times faster to make them commercially viable.
ya but ... : So far the discussion has been a 'Chinese Puzzle Guessing Game' . Without at least a cut-down version of what you're trying to rend- er , it's literally impossible to know what the actual slowdown or bottlenecks are . The problem is usually not the displacement mapping at all , but quite often is simply due to RS trying to anti-alias very fine details that are a result of using displacement mapping , especially if higher render quality settings are being used . We had an almost identical discussion here several years ago where an individual claimed that RS was not capable of any kind of displacement mapping at all . He eventually posted his Disp- map and Frank Dodd rendered it absolutely perfectly with an ex- tremely fast render time . studio
