Denoise only RGB

V-Ray V-Ray for Maya General

The denoiser is great but is it possible to output the denoiser only as effectResult to the EXR without the overhead off all the internal denoise elements? I would like to use the denoiser but keep the EXR file size small, just a EXR with RGB and effectResult.

Best Regards,

Robbert

It’s on the “to do” list.

Good to know it’s on the list… as for now, we wrote a python script using OpenImageIO that runs after our render manager finishes a job. It strips out the denoiser element from our finished renders and saves it as a separate file, works nice and makes the images way faster to comp.

Thanks Vlado! Hope it’s implemented soon :slight_smile:

We really need this feature with our current project because we are dealing with long sequences, 800mb per frame with denoiser, without denoiser we have to much noise. Would be awesome if you could bumb up the priority?

I know it’s not the solution you’re after, but using OpenImageIO to strip out the denoiser works like a charm

Compiled windows binaries: http://www.nico-rehberg.de/files/oii…15_staticMT.7z

Windows command line:

oiiotool.exe -i input_location\input_sequence.#.exr -v --ch denoiser.R,denoiser.G,denoiser.B,denoiser.A=A --chnames R,G,B,A -o output_location\output_sequence.#.exr

Linux binaries are available in whatever distro’s repo and the command is the same.

Just thought i’d throw it out there, it works great for us. You’re frames are quite a bit larger though, so maybe you don’t have the disk space to spare to get it rendered first.

Thanks! I will have a look

Got it working, but it’s really slow, takes like 5 min per frame and i have to do 8000 frames
