I get this error.
"After Effects warning: Expression Disabled. Error at line 6 in property 'Position' of layer 9 ('Stardust 1') in comp 'Color_Ribbons_v06'. Undefined value in expression (could be an out of array subscript?)."
What I'm trying to do
I have several Lights in my scene driving a particle spline emitter using Stardust from Superluminal. They form a "C" shape in 3d space and currently I have this wiggle expression to each light to give it an adjustable Magnitude, Frequency and Time offset. Based on the same wiggle seed. This works at the moment.
These 9 lights should follow the same motion path. Normally I'd just parent this, but the parenting function doesn't translate the motion data to help affect the particle's velocity, inertia, etc. It just moves the system as whole as if it were precomped.
So my hopes are that I can connect them to the null's position in order to affect the atrribute of the particle system. While holding its shape and keeping this wiggle active. I'd also be able to change the entire motion path a single time instead of many times over after duplicating this comp anoth 6 times.
I hope this makes sense, and I attached an image for reference.
