Targa Files and Opacity Map in Substance Painter

Hi there, 

 

I am making a skin for Counter Strike 2. The game shader supports the use of the alpha channel on the base color texture to dictate wear. Usually I use Photoshop to Add a Alpha channel but was wondering whether I can just export the Opacity Input Mesh into the Alpha Channel of my Base Color in TGA format. 

 

I tried to do that but I dont think its working as when I open up the exported TGA in Photshop the Alpha Channel isnt already added. 


Sorry im still new to this so any help would be appreciated.

Hello @Savvas31433608adzo,

 

Thanks for the question.

 

Yes, it's possible to add the Opacity map in the Alpha channel of the Base Color, even with a TGA format. For specific needs, I usually advise to build your own Output Template.

 

 

From there, you should be able to easily create the proper textures.

 

 

Regards,

    When I drag&drop opacity channel in the A slot, I can't get Alpha channel in the exported image. But if I choose  grey channel, I can get the Alpha channel. 

    But the problem is the exported Alpha channel is slightly brighter, as if it's gamma corrected. Can you help me out with it?
