Question

R_G_B_Alpha export problem, need your help please

Hopefully simple problem?

Trying to custom export.

Red channel - ID map (from game)

Blue channel - Ambient Occlusion

Green channel - Black

Alpha channel - Black

 

I have tried multiple texture settings using the user channels.

The RGB export correctly as intended, however...

No matter what I try, the alpha channel still exports as white channel or no alpha at all.

I have tried setting the alpha:  as User01, gray and A channel

What is the solution? besides having to rebuild and fix in a 3rd party program?

Hello @WoTDragon,

 

When you're plugging you User channel as Alpha, set it up as "Gray channel". Should solve the issue.
