I'm having some trouble getting my head around this. I want to use noise as a mask, with another image only showing up through the white parts. I've tried using [pix_mask], but I'm a little lost at this point.
Here's an image to describe what I'm looking for, and a simple patch I've been working trying to get it going. sphere_noise.pd
The image is a fairly rough example. The plan is for the output to be in the GEM window. Thanks, guys.
