Using Adjustment Layers in 3D space
on May 27, 2020 at 6:15:49 pm

I'm trying to make the magnification for a magnifying glass using the Bulge and Magnify effect on an Adjustment Layer. Everything is 3D and there's camera movement but because the adjustment layers cannot be 3D the position of the effects do not line up with the glass (even if I pickwhip the Bulge and Magnify effect positions to the glass layer).

I've looked at a lot of tutorials for this (they're all pretty much the same):











...but none of them address how to do this in a 3D environment with camera movement. Any ideas? Thanks!

the adjustment layer does not need to be 3d. just link the magnify center to your motion path..or animate it by hand...or make the size of the magnification as big as the whole layer and then animate a mask on that layer

I do have the Magnify center linked to the position of the glass and this would work perfectly BUT the glass is 3d and it's position is also being affected by the camera in the scene.

You need to do a layer space transform expression. This takes the 3D position of the magnifying glass object, and applies it to the 2D effect.

src = thisComp.layer('Layer 1');
src.toComp([0,0,0]);
