Hello,
I have a swarm of animated (wings flapping) flies that are following a spline, with a load of turbulence, and I'd like the flies to keep facing the direction they are travelling, regardless of the turbulence. I've read about the Thinking Particles PAlignment Expresso method, but can't figure out how to get it working.
So far, this is what I've done:
I've got the flies facing the right direction as they follow the spline around, all good. But when I introduce the turbulence they are not facing the direction of travel within the turbulence.
In the xpEmitter I've enabled Generate Thinking Particles, and ticked the Ensure Matching Coordinates.
I have set up the Extended Data / Use Rotation / Tangential / Persistent Orientation.
I've got Expresso opened, and got the PAlignment node.
The problem is, I don't know which part of the xpSystem to drag in to Expresso, and which port to connect to the pAlignment node. It's pure guess work for me at this stage, and none of my guesses are working.
Can somebody please help me with this?
Many thanks,
Many thanks.
J.
