Where exactly is the Alpha in the principled shader. I cannot find it?

Thanks

It's not part of the shader. I think you can take the layer output of the principled shader and connect it to a set layer component, and on the set layer component connect the opacity. I am really new to shading in Mantra so there may be an easier or better way to do it.

there is Opacity parameter as well as opacity input directly on Principled shader

Thank you for the help. I cannot make the Constant shader work without a separate opacity map. The Principled shader takes the opacity from the map itself, but Constant does not.

What makes the Principles shader able to take the alpha directly from the map? Looked inside Principled shader but I can't make it out.

** Update **

Kinda figured it out that you need the rgba enabled and get the vector4 > float conversion so you can multiply with alpha. Then it works with the same map, using its alpha.

Thank you!
