Why are generators messing with my masks?

Question

Hi, everyone.

Maybe this is a very basic question, but I am kinda new to Substance Painter. How do you make generators affect only a specific part of a mesh?

I'm working on this dagger and the main colors are working just fine:

But when I try to add curvature and dirt, it affects the whole thing and not just the blade which is what I want. It ends up looking like this:

This is what the layers panel is looking like right now:

How can I fix that? What am I doing wrong?

I would really appreciate any help cause I am about to lose my mind trying to figure this out.

Thanks in advance.

Hi @valenciah.juanpablo,

Thanks for the question.

Smart masks like Dirt are ressources that use the Mesh maps (the maps created at baking) in order to build localized effects. Automatically, they'll cover the majority of your mesh, since the Mesh maps are (usually) baked from the entire mesh.

Therefore, if you want the smart mask to work on a specific part of your mesh, it's up to you to create a mask. I can see in your screenshot that you have regroup all the layers inside the group named "Blade". Now, you can RMB on the group, select "Add a Black Mask", select the newly created mask, and use the Polygon Fill tool with the Mesh fill option in order to select the Blade specifically.

Regards,
