Option to not save junk denoise layers to EXR

Currently V-ray offers no way to choose which channels go into an EXR when we add a denoiser render element. Therefore compressed EXR’s that could be a much needed 5-7mb suddenly bloat out to 40-50mb which is a massive drain on both hard drive space and file syncing online.

I propose the user has an option to only save the effects result channel when adding a denoiser render element so as to keep post lean and fast. Time is money!

Yes, remove the un-needed denoiser elements after denoising. It’s such a no-brainer.

By the end of an animation project, I could fill an entire hard drive just with the wasted data from having denoiser elements in EXRs that have already been denoised.

I really cannot stress enough what a disgusting waste of resources this for everyone involved, for what should be an incredibly quick fix.

I have been complaining about this for years. Does nobody at Chaos care about how much cloud space / data / hard drive space / lack of efficeniency is being multiplied across thousands of users?

I feel I need to add this comment because there is some confusion among Chaos Group staff.

The main problem is the STANDALONE DENOISER

It is when you denoise animations using this tool that we are talking about.

Just write the denoised file down without all the denoising layers.

I’ve described what we plan to do here in this forum thread: https://forums.chaos.com/forum/v-ray-for-3ds-max-forums/v-ray-for-3ds-max-general/1221369-questions-about-saving-of-extra-denoiser-render-elements

Does that sound ok? Should we do something differently?

Does the Released status mean, we can now finally use standalone denoiser and dispose all unwanted layers after denoise?

Delivered with V-Ray 7, Update 2. You can save space now by using the VDenoise tool, and it will remove the unnecessary REs used for denoising.
Separately, we’ve added an option in our “V-Ray Raw image file” exporter called “Save denoiser extra data”. When unchecked, these render elements are not saved.

Hello Dimitar,

I just used Vdenoise - build from 5th September - can’t see any difference or option to not save denoiser data. Denoised image has the same size as the original. Carfe to help?
