which denoiser?

[sean_brown]

Hi super gnu

You can add multiple Denoiser elements, each in its separate channel. And compare in post
the V-Ray denoiser is very good with animations, I usually use that + AI denoiser I mix them in post depending on the results I have.

Hi Muhammed_Hamed . How can I accomplish this? i tried adding 3 Denoise RE and selected each of three denoise engines in each one and selected Render Elements Only.
I rendered out a sequence in multichannel EXR.

when I try to run it in Vdenoise i can see elements are missing and when trying Nvidia i get the error"Could not load vray_optix_denoiser, error [loadLibEx] 126: LoadLibrary failed (126): The specified module could not be found."

Does the temporal denoising do something special other than:

For each pixel
Get its world position
Get the pixels with the same world position (+/- some epsilon) from previous and next frame
Average those pixels
If this average is within some threshold of the original pixels values use the average, otherwise do not change (or lerp)

Maybe do that before running the denoiser itself.

I’ve done similar before in the post, but never bothered incorporating the world positions. Seems reasonable.

I remember a while ago I read on here (I think it was Lele that said it?) that rendering two frames will give you better results on frame 2, than if you just rendered a single frame. Not sure if it's worth the additional render time however...
