How to use one weight layer as a mask for the other

Question

Below is an image of a subdivided plane with 2 different weight layers and 2 different particle systems.

I am curious if there is a fast way to take the weight painting information for my red objects and use it as a mask for my green objects weight information?

• The result would make it so the red objects seemingly cut through the green objects.

Thank you so much everyone!!

Answer 1

You can either use the Vertex Weight Edit modifier or, more simply in this case, the Vertex Weight Mix modifier:

Which will let you subtract the band group from the circle group:

Ensure 'Use Modifier Stack' is checked in the particle system..
