there is a new operator now in the light groups panel. You can apply your light groups modifications with it. It allows to use the AI-Denoiser and render faster when you reached the final version of your light setup.
The operator will also:
- automatically clean the light groups passes,
- clean your compositor node tree
- and if denoising is ticked in the light groups panel, it will also setup the AI-Denoiser node tree on top, with the settings you have chosen.
All that in one click and you are ready to launch your final render!
On top of this new feature, you also get all the latest improvements of Blender 2.83.5 LTS and 2.90 beta :)
