Rotation travel direction and spin

[insertmesh]

Hey there,

I feel like I asked this before, but I couldn´t find it, so here it is (possibly again):

Lets say I wanna animate some particles and use travel direction to have them rotate towards their velocity vectors. Why is it not possible to add a spin operator on top to have them spin on their local axis, while rotating towards their travel direction? Like arrows, that also spin while they travel...

I feel like this should be possible, yet I couldn´t make it work.

If I´m just missing something basic, please let me know, otherwise I´d put that in as a feature request.

I'm facing exactly the same thing, spin and rotation by travel direction cant work together.

Don't have the time to try it right now...

But just a quick idea (if you have a deadline).
Maybe you can try animate arrow (real model) spinning on it's own axis, and in shape operator, turn on the animation.
Then for the global orientation, you can add a rotation - travel direction.

If that is not working, maybe try and use simple actors, and they should have count always their local animation

Hope, some of this helps

I actually am facing the same problem, was experimenting with it, and found this topic.
While animating the original geo could be one way to do it, it becomes way slower, and if you need to do things where you need the spin motion to advect other particles you dont have. it.  So will be great a solution  to have a spin in top of a travel direction.

Hi guys, hope it'll help!
