Paint in Opacity like a Mask

Poinball

Hey, Is it possible to paint in a mask that control the Opacity channel ?

The only way I see to use Opacity in substance is to import Bitmap ...

Thanks for your time !

Yes, you just need to enable it near the place where you bake your meshes. Then it's simply painting the opacity the same way you paint any other channel in painter.

Can you show me it on a screenShot please? I really dont see it

NoRank

Sure, here you have it.

I already enable that, But how do you paint in this channel ?

NoRank

When you do that it will enable the opacity channel to paint here, you just have to select and paint. To see the results in realtime you can change the shader under the viewer settings tab.
