I have a fingerprint PNG on my circuit board and I want to be invisible except as the glass of the magnifying glass passes over it. Can I link a mask (on the fingerprint layer) to the motion of the magnifying glass?
I'd also like the fingerprint to be a shimmery red and I figure I can use fractal noise or the heat distortion effect as a source of the shimmer but I don't really know. Can I restrict the grade layer to just the black parts of the PNG? I can change the PNG to red and apply the heat distortion and that looks okayish.
