Alpha Expression Overrides the RGB?
Posted: Fri Jul 30, 2021 5:53 pm
Hi,
I'm aiming to have an alpha from the fresnal pass (grey image).
1) To create an alpha from it, I use Bitmap node set to luminance.
2) To process it further, I use Custom Tool node to set alpha between 1 and 0 only.
It works. The problem is the RGB is also affected. I want the Alpha only to be affected.
You can see an illustration of the problem here:

If you want to check the sample fusion file. You can check it here:

Thank you
