Here's a version rendered in C4D + Octane

Good to hear! Let me know if have any questions.

Thanks for the shout out. It’s been a while since I’ve updated Proximity but it still works in AE 2025. I’ve considered a big update for it but I don’t know if there would be much interest.

When merging shape layers they aren't both shapes in one layer, it's a single parametric rectangle to so it's easy to apply rounding and use the size property.

What about making new comps from the comps in the timeline? That would be cool... okay let's do it. Merge masks too while we're at it.

I've never actually checked it out before. I took a look, they are similar but tackle things a bit differently.
