Hi,

In Corona Image Editor, light mix was working with EXR file, not sure now, anyone cam confirm this…?
Light Mix and one lights are added in Multi-pass. (IR and Image editor preview attached).

Thanks.

Just to be sure we’re all on the same page - LightMix never worked with .exr files, only with .cxr files (which are Corona’s modification to the exr file format, containing extra custom data needed for denoising and lightmix). So, do you mean you have a .cxr file that used to load with LightMix but now it doesn’t? Or do you mean you accidentally saved from Corona to EXR (in which case, LughtMix would not be expected to work)? Or you are saving to a CXR file as needed, but LightMix isn’t working in the CIE after that?

Thanks Tom.
I miss .cxr in drop down save… I was also thinking how .exr with corona image editor…! Thanks.

Thanks.

Are there 3 individual “light selects” set up in the multi-pass settings? Screenshot?

5

Yes… 3 individual lights assigned in multi-pass…!
in beauty pass menu… it is showing other 2 lights and third light is in lightmix…!

and “Background layer still disappear if do some setting in IR Post” it is a bug or corona proicess like this…?

Problem solved, after renaming your lights in the multi-pass settings everything is working as it should. All 3 lights show up in Corona Image Editor.

Thanks.

I’m not talking about IR, As you can see from my example, it is opened in the CIE as test2.cxr, all lights are there. Make sure you are naming things correctly, for changing them fixed it for me. As for the background, I have no idea, it’s showing for me too.

Yes, done. assign the light names and all works well.

See if it is auto naming possible when drag light in lightselect… will a bit handy.

Thanks for that.

and Background layer…?

…

12

Autonaming is possible, just drag the light into the name slot and the name will be updated. Or you can use the Setup Interactive LightMix button to automatically set it up for you.

Thanks bean.

and other one, Background layer…?

…

14

No problem. Not sure about the background layer, can you add some screenshots for me? Thanks

15

On “PS doesn’t open .cxr” - it will if you rename the file to .exr :wink:

16

sure… I uploaded video… easy to understand.
You can see in picture viewer background layer disappear if do some setting in IR Post tab.
