Need some help with vray :(

[Anonymous]

Hello community! i have been searching around the internet for ways to improve the render quality with v-ray renderer, i keep getting this annoying noise problem with my renders even tho i set the global dmc higher. Is there any settings out there that can remove those noise and also any ways/settings to improve the overall quality of my renders? any help will be greatly appreciated!

oh yes and also, i'm using HDRI for the environment and dome lighting with the same hdri map as the one used for environment.

Which Vray version you are using?
If you are on 3.0-3.2 get 3.3.

It helps alot on the sampling side.

Regardless on which version you are:
Raise min Shading rate to 6.
Afterwards turn down the global subdivision multiplier to 0 to kill ridiculus subdiv settings you might have made.
Leave everything else in the dmc settings to default
Render, you propably will get a way cleaner image.
Control the noise with the noise threshold. A value of 0.008 should give a quite clean image.
If not something in your scene is wrong.

Also dont use environment and dome lighting at once, the dome will do a good job on its own!

If your rendertimes are to high than, check your reflection bounces.
Materials with goss of about 0.6 and lower will only need 1 0.8 need 3 and 1 need 4-6 in most cases.

I did all the instructions that you told me and it didn't work, the noise is still there. The render time is super fast too, it's like 5 mins per render lol.... I'm using 3.2 yeah, cant get 3.3 >.<. Any possible problem that's happening in the scene? I havent really done anything special. Just apply vray materials onto poly, used hdri environment map and a dome lighting with the same map as the environment.... yeah that's about it... nothing special really

Have you used the vray hdri map for the map of the dome? You should.
Again, dome is made for work on its own without any aditional environment map.
Check for hidden lights or two dome Lights.
Raise the min shading rate a bit more.
Add Reflection, Specular, Direct light and Global Illumination Render Elements to see where the noise comes from.

If you have a licence for vray 3.x you should be able to download the newest version...
