White Speckles / Noise

[hubmer3]

Any tipps or hints for reducing the noise?
normaly my machine (HW see signature) would clean this up in less than 2 hours, here i guess its a light in the scene what causes this....

vray 3.60.03
BF+LC / Progressive
2:1 4096x2048 (120min) reaches only around 40 Passes!

Thanks in advance for any tips.

Hello,

The reason for this could be if a VRayLightMtl is used with Direct illumination - ON. Nevertheless, can you send the scene for investigation?

Ok, thanks i will check that! the problem is the scene is quite heavy and uses a lot of xrefs ~ asset colletc will end up with ~ 10-20gb. i'll go through the lightmtls with vmc quick!

thanks

Hy! I managed to clean up the whole scene again:

i found standard mtls / from merged models
lights where totaly off with default vaules
exposure was incorrect so i boosted noise

it takes me a whole day but ive learned a lot about the „lumen“ workflow

case closed!
thx
