Title: Material ID and Corona Decals
Post by: steppes on 2022-06-06, 13:07:00

Hi All!

I love the new Corona Decals, but unfortunately they are not shown in the ID Pass. It would be great, if the opacity of the decal would be shown in the ID Pass or another mask.

Thanks

Steppes

No one else?

Or is it already possible but I cannot figure out how it works?

That would make decals even more powerful.

Hi guys, This should already be working. Here are some things to consider...
- The image must be true B&W. (The ID mask only shows the decal transparent in places where it has 100% transparency)
- Enable ''Clip'' in the opacity channel.
- In the decal object, ensure ''visible in masks'' is enabled.
- In the ID pass, set it to ''Instance'' or ''Object''.
- Render ;)

Hope that helps!
