Hi!!

I want to add to the simulation I upload, an initial rotation (in X) to the object (particles) that follow the inertia without putting keyframes, but in the pop drag node I can't modify the rotation. I tried to do it with different nodes but I couldn't make it work.
I think the only way is doing it with vex code, but I don't know how to do it.

Thanks!

Doesn't the solver have an initial velocity field? You might try there.
