A Mask within a Mask?

[BaidDSB-3D]

So i work with blender on there in texturing i can make a mask and create seperate masks INSIDE the first mask.

Is there a way to do that in Painter?

For example: Im making a steel chair. Its going to have Painted Metal as the base. Now i want a mask to show metal edge wear, so there will be parts of exposed grey metal.

Now WITHIN those parts of the grey metal which is exposed and has no paint, i want to have a mask so that SOME parts of that exposed metal has rust.  So a mask, within a mask.

This is my absolute first project in painter so evrything is still new.

Hello @BaidDSB-3D,

Interesting question.

You can't add a mask within a mask, this isn't really the current type of workflow with Substance 3D Painter (with that being said, the folders can have a mask and contain masked layers).

Within a mask, instead of another mask, it is possible to add several layers. Usually it's these layers and their Blending Modes that will build a complex material.

To take the example of the rusty steel chair, that will need two separated layers, because those are two different type of materials (unpainted steel and rust). Basically, you'll need the rust to use the mask of the damaged steel and for this, the Anchor Point is the perfect tool.

To make it simple, the Anchor Point exposes the resources where you placed it and you can use these exposed informations later on in another layer.

Tell me if you need anymore guidance.

okay this much i was able to get working. using anchor points i was able to contain the rust inside the damaged paint mask that exposed the bare steel layer below.

the question now is how to further control how much is the rust spread inside the bare steel. while i used levels to contain it, i also want the rsut to be present only in the very specific areas i want it to show on.

So picture the chair. Blue paint is present everywhere but chipped off at the arm rest. so the arm rest is showing the exposed bare steel. now inside the bare steel, i want only a very few tiny spots where the rust will show. currently the rust is containe inside the bare metal area but i want to further control it.

Usually, when you need to paint on a very specific part of the model, you'll need to add a paint layer to your mask. Therefore, you can add a mask to your rust layer, add a paint layer and a fill layer with the anchor point set to multiply. But a picture is worth a thousand words

thanks. this worked perfectly.
