Stencil on top of widget

I’ve got a few complicated post process materials that utilize the stencil buffer.

I would like to be able to see the stencils on top of my ui widgets. how would i go about achieving this?

I know the ui pass occurs after post process, is there a way to supply the stencil alpha produced by my post process to a widget material in screenspace or something similar?

or some way to display the results of the post process material on top of the ui?

I can’t think of a way to achieve what i want
