Substance Painter - Exporting Opacity

GarethStandfield

Heya again.

When i add an opacity too the preset it does not change inside off the export window, i tried making my own preset but i dont know what channels an opacity layer would even export as? its only this one part off the mesh for the cornia but its vital an the only map a youtube tutorial i follow generated was a broken file that i could not even open on my machine? anyone have an idea how i can bake out an opacity layer from substance even if sepretly from my other maps?

The bottom picture is the preset after adding opacity, as you can see it does not change.

Drop down the config menu, and pick a different preset. You could also just go into the config settings and make a custom one, baking out only opacity, and have that as your Config.

Thanks i got a channel out onto a file this time, its in the right place but seems to do nothing at all when applied too the mesh/model still? im not sure if i did something wrong in exporting or in sketchfab/maya sorry if this is obvious but maps are currently the bane of my existence haha

You need to switch the shader in substance painter to "PBR-metal-rough-translucent" in the shader settings menu:

Sorry im not sure how to reply too people, the post above i can see them fine inside substance using "PBR-Metal-rough-with-alpha-blending" the issue is when the map comes out it just doe nothing? i put it though the gray channel an it came out like the picture you see above
