A bet-ter solution can be found in the QMC sampler set-tings. Don’t go higher than 40 trying to reduce the noise. ![]() ![]() If you want the noise to be even smoother, in-creasing the subdivs will not always help. QMC settings: smooth the blurry reflections even more If you have many blurry reflections in the scene, adaptive QMC will always be faster.ġ9. The adaptive AA smooths outs much of the noise from the low subdivs. Make sure you have the AA sampler at adaptive QMC when using high subdivs values!! If you want to use adaptive subdivi-sion AA, you can get away with much lower subdivs values (3 to 10). Doubling the subdivs will take +-4 times longer to render! Note that 8 subdivs means 8*8=64 sam-ples, 20 subdivs means 20*20=400 samples. Smoother blurry reflections The subdivs value beneath the refl glossi-ness controls the smoothness of the blurry reflections. There is much confusion about this, many people will mix up the term glossy with blurry.ġ8. Glossiness means ‘shinyness’, so glossi-ness=1.0 is 100% shiny, lower values are non glossy or blurry reflections. Play with the glossiness value to see what it does. But by using the glossiness parameter instead, rendering will be a lot faster. ![]() To create this effect in 3D, you could also put a very fine bumpmap in the bumpmap slot. This is the effect you get on real objects from very small bumps in the surface.
