Exporting base colour with some sort of transparency

[Ash0802]

I've got these textures I would like to export, but I want the base colour in certain areas to have a certain level of transparency.

for example right now if I had a regular cube mesh, and I painted 5 of its faces blue and one of its faces green and I changed the opacity of the green face to 50 or something, how do I export it with that 50% transparency?

Right now it exports as a solid colour even if its opacity is changed, I have to go into photoshop and manually change it by selecting the areas I want transparent and changing the opacity and then saving it as a png in photoshop, is there a way to do this in substance painter so i don't need to do this extra step in photoshop?

what shader are you using? You'll need a pbr metal rough with alpha blend. Change to that and then add an opacity channel to your texture set. Then enable that channel in your layer and adjust accordingly
