I have observed this a few times, too. I think it would be best to give us some control over this, either as a switch or as a balance parameter which drives the 'bump awareness'.

Exactly this. Especially if I want to develop a quick draft render for a client, the older denoiser gave quicker results

Corona 2 introduced preserving detail on bump maps when denoising, which would make 1.7 the version before that appeared. As a note, any scene saved in a newer version of Corona is not guaranteed to work in an older version.

You might also try either of the new AI denoisers, the NVIDIA or Intel ones, rather than revert back to an older version of Corona.

Hi Pokoy & Monkriss,

yes, the issue you noticed is correct.

This is why I switched back to the Beta from 21.12.2017.  -   Core 1.7 hot fix 2 !

Works great and - as you say - provides muuuuch quicker previews, since the denoiser is applied equally on all surfaces.
For quick renders we don't need crispy bump maps, right? We need images that don't fall apart in areas that are already smooth and bump map areas that stay super noisy even after many passes.

Also displacement stacking works perfectly in Core 1.7



Yesterday night I tested the new Corona 4 (Beta).

Denoising over the new integrated CPU AI - denoiser seems to deliver okay results!
Also displacement on stacked materials and poly selects works nicely in Corona 4 Beta.
As far as my test...


Testing right now on a more complex scene that was previously made in Core 1.7 Beta.

It seems to have some problems with converting textures, when opening it in Corona 4 Beta -  like metals with maps on specular. It doesn't interpret the specular-maps correctly, especially if they are in a filter.
Also HDR on Sky objects don't work properly - only after you erase the old HDR and create a new one with the same HDR-texture.

Hey Tom,

I can absolutely support your suggestion to try the new Corona 4 Beta.

I am using it right now for a large project. Everything seems to function very well.
Have been testing it for two days in this project and even have the impression that the new AI denioser delivers better results quite faster.

Good job, guys!
