Title: How to apply denoise to the Whole image after a render region---
Post by: gabyanz on 2016-11-25, 11:19:21

Good morning...

probably the answer of my question is very obvious, but I'm really struggling in finding it... XD

Let's say I've completed an image and I've applied a full denoise. Then, I have ro re-render a small region of the image beacuse of some requested changes.

at the end of the region render, the denoise , applies only to the region selected, and the rest of the image previously rendered is not denoised anymore.

There is a way to "burn" the denoise to the image... or I perhaps I could apply the denoise to the whole image?

Thanks in advance, I hope my question is clear :)

Maybe uncheck: Render Setup>System>Frame Buffer>Clear VFB in between renders?
I think it would solve your problem.

It is already unchecked :/

Does it happens only to me? :/

That's it

Thanks!!

This works... but I thought it was possible to do it into the Corona Buffer...  the corona region render is very handy...

So using max region is the only way? We can't apply denoise to the whole render using the region render in corona VFB?

Denoising relies on some additional render elements, which need to be rendered, but are invisible to the user. My guess is that when you are using Corona's regions, you are limiting those special elements to the selected area only, so there is no data how to denoise the rest of the image. But if using 3ds Max regions works, then I suppose this should be improved.

Might be related to this: https://corona-renderer.com/bugs/view.php?id=2290
So I would suggest checking this in the next daily build.
