I want to design a base material with an opacity map. But Designer's base material node does'nt provide any opacity entry. How can I do to publish a sbar PBR with opacity ?
Thank you !
You don't need a base material node at all. If you use one of the preset templates, under file new Substance Graph then it will be set up with individual output nodes.
If that template does not include opacity then add an output node and in properties set the following:
Identifier to opacity
Label to Opacity
Usage to opacity (note you will have to click on Add Item to get this.
That is it - you now have your output to which you can connect your graph's opacity and can publish in your sbsar.
The same principle applies to any other output you want to add.
