Trying to export material with brush alpha - Confused on how to.

Hello Substance 3d Community.

First of all, I would like to say I am very new to using SD and my learning has largely relied on YouTube tutorials and anything else I could find online so please bear with my lack of knowledge.

I have a material which makes use of a number of alphas that I can choose between via a multi switch node. These alphas are used to create normal, specular, glossiness and diffuse with various nodes editing them in-between. I attempted adding another output node where I'm outputting the results of the edited alpha as-is, but after export, it's impossible to drag the material to the alpha input in painter.

I worked around this by creating a separate package, including my alphas and relevant nodes and exporting said graph with unspecified type so I can import it as alpha in painter. This means I need to match the settings of both alpha and material however and is simply a hassle.

So my question is: Is it possible to somehow include an alpha/brush in the material export? Am I doing something wrong?

Thank you.

No, that's not possible. You'll always have to control the material and the brush's alpha parameters separetely, but if you want to detail your project, I could give a more specific help.

Hi @26936881,

 

Thanks for the question.

 

It's not possible to have an alpha used in a brush with exposed parameter linked to a material.

 

But you could remove the alpha from your .SBSAR material, and replace it by a simple "input" node, where you'll be able to place your parametric alpha directly in Substance 3D Painter.

 

You could also extract a part of your graph in an ouput named "user", and use it through anchor points as mentioned here.

 

Tell me if you need more guidance.

Hello Cyril, thank you for the response, it's been helpful. I would like to ask, is it possible to somehow point that input to the brush's alpha directly?
