In a relatively simple interior room, what value do I need to use for a good-looking render?

Many good questions generate some degree of opinion based on expert experience, but answers to this question will tend to be almost entirely based on opinions, rather than facts, references, or specific expertise. If this question can be reworded to fit the rules in the help center, please edit the question.


There is no works-for-everybody setting. Basically it's a trade-off between render speed and image realism.

I would suggest to turn down each number of bounces to 0, just so you see what happens then. Then start increasing one of the numbers, and see how it affects your image. The aim is to keep the numbers as low as possible (to get a fast render) while keeping them high enough so that the image looks the way you want it to.

  • $\begingroup$ Those appear because Cycles randomly samples your scene by shooting "rays" into it and letting those bounce around. If such a ray happens to bounce straight into a lamp, you'll get a white pixel. If it doesn't, you get a darker pixel. With only one sample per pixel you'll clearly see those white pixels. With more samples Cycles can take the average and smoothen them out, removing the fireflies. You may want to read through 7 Ways to Get Rid of Fireflies. $\endgroup$ – dr. Sybren Apr 1 '17 at 13:01
