Hello, everyone,
I have a png texture looks like as below:
above snapshot was taken from Texture Editor, only toggle on Channel Green and Alpha:
In Texture Editor, it use sRGB configuration:
What I want your guys’ help is:
In a material, how can I combine the channel algorithm to get a node just preview like it is in the first picture?
I tried this method （from a youtube video）:
but as you see， the preview of subtract had red value. Not I want.
Use UE4 version 4.26 to try all of these.
It’s just the preview that’s red, it’s a 4.26 thing. Have you tried plugging that into the material?
Oh, I though it was wrong when I saw red channel like thing.
Try to plug other nodes , seems you are right. Thanks.
But still some problems,
I test some values (in my material, the name “Percent”), seems the angular gradient output isn’t right. For example, in the picture above , when I use 0.5 (50%)percent, output value seems still has 0.7(70% percent part of whole visible arc bar) to 0.8. Am I missing sth?
Not quite sure what you’re trying to do with the IF node…
