vray rt noise/grain problem :( its doing my head in.

[afkariaziz]

Hiya,

 

I have been doing lots of reading and how to optimize the vray for advanced and rt.

 

Rendering on Advanced is all good. I have a major problem with RT.

 

I have an interior scene and all materials are doing ok. the lights are optimized.

 

When i start to render, it turns out noisy and grainy. It annoys me. I tried to redo the settings and over and over again yet i am getting the same annoying grainy and noisy render.

 

I am rendering with geforce 640M GT and cuda. I tried on the radeon 7700 series with Open CL.

 

They are both the same resulting in same grainy and noisy image.

 

Any advice would be great...

 

thanks...

RT is only meant for preview purposes for near-realtime look dev. By default it first undersamples the scene so that it may give you instant feedback giving a very grainy image, and then continues to refine with pass after pass ultimately leading to a clean image much like the "Progressive" image sampler option in your render globals.

hi.

Try unchecking the Probabillistic LIghts in Global Switches.

You have to be in Expert mode to see it.
