Fuzzy renderings - Fuzzy & Pixelated Edges ???

[mailerik]

I am having a problem with my renderings. On the image below you can see where i point out the area. I am getting fuzzy pixelated renderings and edges. Your help is greatly appreciated. Any comments on my work will be great also. here are my settings:

Any body? Please. Any advice will help.

I don't know exactly, but it has something to do with sampling in scenes with low light because of LWF or perhaps color mapping. I encountered the same issue on an exterior rendering in the shaded areas. My solution was to crank up the QMC sampler settings: Adaptive amount 0.5, Noise threshold 0.001, Min samples 16, Global subdivs multiplier 16. I also dropped my IR map subdivs/samples to 8/20 to account for the higher subdivs multiplier. Things will render slower but you should get better results. There might be a smarter/faster way to solve the problem though.

Also, IR/LC is often faster than IR/QMC for interiors.

Also consider trying Vlado's "universal" settings:

Hi, I had the same problem, in my case helped in QMC sampler settings to increase adaptive amount to 0.9 and decrease noise treshold to 0.001.

Ok, changing the Adaptive amount and the noise threshold under QMC did the trick but at the cost of an extra 9minutes! Any other time saving tip?

thanks again

Only 9 minutes extra? I would consider yourself lucky.

decreasing noise threshold will bias the QMC AAser towards max subdivs.
Setting those high enough, with a low enough threshold, will clean those edge issues.
If the settings are high enough, you might even deactivate the reconstruction filter entirely (area, blackman and so on), as the high AA settings will take care of all you'll need, and that might shave some time off your render.
