Exclude A Visible Object from Corna Alpha Element

(1/1)

Charlie Nicols:
Hi, it would be great to have the option to exclude an object from affecting the Alpha channel whilst the object remains visible to camera.

3DsChobo:
Maybe this is helpful?
If "always black/white" is not what you are looking for you could also use a masking element and uncheck "visible in masks" for the specific object.
What is the purpose for this alpha anyway? Maybe there is another way.

kevinalter:
Yes, I understand this.... But.... Going into all 20 material slots in a multi-mat to turn off the alpha is pretty sucky for something like a tree mat that has 20 mats in it. It would be better to also have an option to remove from mask/alpha BY OBJECT!

maru:
Hi, here is a script you can use to change alpha to "always black" for all materials currently selected in the Slate Material Editor.
You can change the number "2" in the last line:
0 - Default
1 - Always white
