Using multiple stencil textures


I have a head material which contains multiple textures. There’s a stencil texture for the eyebrows, followed by a simple color texture:

There’s a second stencil texture for the beard followed by the same color texture:

The problem is when the stencil is enabled for the eyebrows, its preventing the beard from appearing:

It seems like the first stencil in the stack applies to all subsequent textures. Any way this can be avoided?
