Hi guys,
I'm having a problem with this scene, it's an underground parking lot and I have to put in a small shopping strip inside it... Everything's working well so far, lot's of materials have glossy reflections and at 8 subdivs they all work fine - problem began when I added glossy ref. to the asphalt material. Everything is reflected properly and without much noise EXCEPT for the lights which are reflected in an extremely noisy fashion. The reflection is of 3 tubes inside each lamp, they have a vraylightmtl encapsulated in a vraymtlwrapper so they don't output GI. I have tried raising the asphalt materials subdivs up to 256 with no result - it become a bit less noisy, takes eons to render but still doesn't look half as good as it should... I've tried changing the QMC sampler setting down to 0.1 adaptive and 0.0 noise thr. but the result is the same... Ive also tried changing the QMC image sampler to 2, 8 with 0.001 noise thrs. with no real improvement - once again, it's a little better but not OK in any way... Also played around with color mapping, turning on sub-pixel mapping and clamp output, but it didn't do anything.
The material settings are pretty standard, it's an asphalt texmap with 0.96 glossy value, 128 reflection amount, and ward BRDF. No other maps - no bump map or displacement. The camera is a vrayphyscam set to still mode, f8.0 shutter 1/200th and 100 ISOs, with exposure ON. I'm rendering using LWF, output gamma in max is set to 2.2 - color mapping gamma is set to 1.0 so it doesn't get corrected twice.
Here's a rendering, the noise is pretty "loud" in the bottom of the image.
Here's the settings:

I would like it if this thread could steer back to the problem I'm having, 'cos it is a doozy...
