3d stroke expression for particle world. Attaching one null to another null.
Ive got it all set up properly. My particles are attached to a null in x,y and z space just fine. But i wanted to attach that null to another null and spin around it. Trying to make christmas tree effect.
My problem is when i attach the particle control null to the roationtal null, my particles are now way off course. They still follow the null but are way off on position. I could have sworn ive done this before. But i cant get it to work now.

I have not animated anything yet. Everything is the center of the comp.

If you’re trying to get something in AE to follow a layer, it’s no problem. However, if that layer then becomes parented to something else, you need to use the toWorld expression otherwise it’s looking at the parented values.
The expression would look something like:
L = thisComp.layer("Child Null");
L.toWorld(L.anchorPoint)
Where Child Null is the name of the layer you want the particles to follow. It’s easiest just to pickwhip that line after the = symbol.– The Great Szalam
