Title: HELP_Shadow Catcher Glow
Post by: dipozzo on 2020-09-12, 18:27:11

Hi!
I am working on an animation and I need to export a png (or tiff) sequence of words with light material.
These words must illuminate the planes on which they are placed (shadow catcher).
Problem: I cannot save the halo of light on the plane.
The alpha channel (as you can see) doesn't include it.
How could I do?

Thanks so much!

You can do this by adding the Indirect pass

Thank you maherkhedder!
Unfortunately the problem with the multipass is the background. I would need a transparent background. Do you know if there is a way to achieve this?

Yes, you can do it. enable the alpha channel and put the pass. When you composite the scene in after effect or photoshop, set the blend mode of the emession layer to (add).

I can't get rid of the black of the pass, it's certainly a simple thing and I'm wrong.
I attach the psd file of the multipass. Could you take a look at it?
It's something that would help me a lot in future jobs too.
I really appreciate your help, maherkhedder, really!

I forgot to put the image under the layers.
It works!
Thanks again for your help!
