15,000 iterations

alienarea

Most of the light sets I use are limited to 15,000 iterations. For some scenes, when I set the render quality to 10, the render stops at 15,000 iterations, but not a 100 % of the picture have been completed.

If I switch off render quality and let the engine run for 15,000 iterations, is the result the same?

Any render quality above about 3 or 4 is a complete waste. If you're rendering to 15k iterations you've likely achieved all the quality you can reasonably expect to get. Look at the image. Are there any obvious unconverged pixels? Then you're fine. I wouldn't worry about % converged but instead on the image looking decent. Also the denoiser has no effect on the % converged so if you're using it, and you should, then you just need to pick a number of iterations you're happy with.

You probably don't need 15000 iterations either, providing your scenes are properly lighted.
