Title: Denoising Cube Maps
Post by: mabulsoud on 2023-04-28, 15:21:10

Hello,

We render a lot of cube map walkthroughs at my office but we can't use the denoiser because it causes seams where the different sides of the cube meet. It would save us a lot of rendering time if we can just use the denoiser for the last bits of stubborn noise. Is this a feature that's possible to implement?

We have the same issue with the sharpening/blurring effect, but that's more of a nice to have where as the denoiser would really make a huge difference.

Thanks

Switching to spherical panorama was the only way for us to solve this problem.

The software we use to process the tours doesn't accept equirectangular images unfortunately. Regardless, Going that way would also increase the amount of pixels that need to be rendered by 33% which I'm not sure would be worth the tradeoff. Is there anyway this feature can be added to cubic panoramas?

I think the suggestion was to introduce one middle-step, render equirectangular pano and convert to cubemaps for further processing in your own pipeline.

That could work as a temporary fix. I've tried googling and couldn't find a software that does that especially for 32 bit images. Do you have any recomenndations?

I don't have it installed right now on my PC, but PTGui should be able to do so.

Thank you I will test that out for our next project.

Still getting denoising to work for cube maps would be the most efficient solution. I hope the Corona team can look into this.

Hi,

I was able to reproduce the same issue on my end and I have logged in our system to be further reviewed by our devs.

We will let you know if there are any updates on this.

Hi Avi,

Are there any updates on this issue? Would be great to be able to denoise cubemaps sooner rather than later
