Help Aerodynamics for non cloth

[Jawsarn]

Thank you for clarifying.

What I'm moving is the attached transform that is child of solver. See video.

Nevertheless, note that in the case of a character you’ll need to take the solver out of its hierarchy and keep it static (that is, perform the simulation in world space) for this to work, otherwise particles won’t have any velocity relative to the solver and aerodynamics won’t have any effect.

Do I undersand correctly that I would have to parent the character to the solver outside then? A tangential question there is it better with fewer solvers in the scene? Or performance overhead to keeping the whole world inside one solver (actors and not, apart from unity hierarchy perf).

Don't you think calculating the forces manually to apply as wind is a better approach then if possible? At least for managing scene stuff. (Or just the solution you may add below when added)

If this is an inconvenience in your case, I can add a option to consider the solver’s velocity when calculating the relative velocity during aerodynamics. This would allow aerodynamics to work in absence of wind even when particles are not moving at all relative to the solver.

This seems to be a good option that would solve for the effect I'm after for the ears right now.
It alone would not "solve" the general issue I'm observing with inter solver particle movement though (if I'm correct in what I'm observing that is).


Thanks a lot for the assistance!
