Align sprites with actor velocity

[weirdgyn]

I’m trying to use Niagara to create a fire FX for a flying (hit) airplane … flames should appear around the fuselage (more or less in the engine area) but should distribute along fuselage following air streamlines (i.e. parallel to the fuselage main axis) … I tried using gravity, velocity and so on without luck.

This’s the best result I can achieve:

and this’s the matching Niagare effect settings (I can detail sections if needed):

as you can see smoke (a different FX) is correctly aligned with the fuselage axis (simply rotating its emitter origin)

Any help?

Click Particle Spawn + button and look in Forces for Acceleration, Linear Force, Vortex Force, and Limit Force. Those would probably be applicable to flames spreading along a plane. It may require any of those to be added to Particle Update instead or in addition.
