Title: Living Room WIP help needed.
Post by: Francisco Barrera on 2013-10-05, 20:37:01

Hi, i am currently working in this scene but i cant seem to get it right, i have tried multiple settings and still getting fireflies :(

Hopefully someone can help me, i rendered this image for more than 9 hours at 1000 passes 1080 resolution and still getting fireflies.

Settings are the default except for HD Cache as second solver.

Thank you for your time.

P.D. Sorry for my english

What exactly do you mean by fireflies? Noise in areas covered by lights? Increasing "lights samples multiplier" might solve this. This will cause more samples to be used in areas with direct lighting at the cost of other areas in the same time. If you mean something different then you should check your scene for these errors:

-unrealistic materials (for example glass with 100% transparency or metals with 100% reflectivity)
-explicitly high bump value
-solid glass used for windows
-lack of portals in window holes
-overlapping polygons
