Interactive LightMix doesn't refresh when render viewport selection

Corona 1.6 + 3ds Max 2016

I started with this render:

After I decided to rerender floor. I set Render selection: Viewport selection, then selected floor, updated it material (for better understanding I made it with solid color on diffuse) and hit render.

Beauty pass, it’s ok:

And alpha:

Enviroment LightSelect element, it’s ok too:

Ceiling LightSelect element, it’s fine:

Summary, Interactive LightMix element, that should be the mix of two previous elements contains the old floor, from the very first render, that was made before I update my material:

Hi,
I have exactly the same issue (pretty big one when you attend to save time rendering just a wall to present a client different versions :confused: ). I was about to write a post when i saw yours …
I’m using the last version of corona & 3ds max too.



I have trouble reproducing this. Can you send me step by step instructions?

Here is what I did:

Created a scene with a teapot, two lights, and a box as a floor.
Assigned textured material to the floor.
Set up LightMix automatically.
Rendered the whole thing.
Stopped rendering.
Adjusted LightMix.
Closed vfb.
Changed the floor material to solid color.
Enabled render selected > viewport selection.
Selected the floor object.
Disabled “clear vfb inbetween renders” in system settings.
Rendered.
Checked beauty and LightMix.

Guys, did you use denoising in your examples, or at least did you have denoising enabled?

Yeap!
I think I know what is it.
When denoising is enable, Interactive LightMix element chages only when denoising is finished. Is it bug or just a feature? :slight_smile:

I made simple video to describe this situation better. Sorry for my english :smiley:

Ok, so it must be the same thing as Lightmix pass blending with previous render with denoising - Corona for 3ds Max :: Issues - Chaos Forum

Yes, I think you can merge our topics.
