AE Expression to move in Z Space (stratastencil)
Hi There,
I’m trying to achieve a stratastencil effect in after effects. It’s working ok, but I feel it could be better. I’m using this expression to send each layer backwards in Z Space
veloc = 2000;
x = position[0];
y = position[1];
z = position[2] + (time – inPoint) *veloc;
[x,y,z]This isn’t perfect, all the objects are constantly traveling backwards which doesn’t really give the desired stop motion style effect. Does anyone know how I could modify this expression so that the layer ‘jumps’ back every second frame? Or can anyone suggest a different expression?
I’ve also tried manually setting up each layer to jump back every 2 frames, but since that resulted in pre composing the layers to avoid a unworkable timeline, it affects the lighting/shadows.
I hope this is clear, in case it’s not this is what i’m trying to achieve –

Something like this should work:
veloc = 2000;
f = timeToFrames(time-inPoint);
zOffset = framesToTime(Math.floor(f/2))*veloc;
value + [0,0,zOffset]Dan

Nailed it!
Thanks Dan, worked a treat.
