Using a shape to mask or reveal an image

[Aphex-Twin-Peaks]

Hello cablers,

I'm trying to setup a mask using a shape to either reveal or mask an image. Ideally what i'd like is for a shape to reveal an image through said shape over the top of another image, with the shape controlled by cursor. I think I can work out the cursor stuff fine but after many attempts using the alphamask op to apply a mask via a shape I can't get it to work.

Has anyone achieved this?

Hope this clears things up as it's not too clear what you mean

in a imagecompose context, you can easyly take any texture and use it as a mask, it has an input for that

Thanks for the tip. I'm new to Cables but it is starting to click for me.

Thank you Andro! Apologies for my ambiguity. I struggled to articulate exactly what I meant – but on first inspection you've nailed it for me. Thanks so much!
