How to stop particles from rotating after spawning

I am creating a trail effect attached to a projectile. Basically a ‘ring’ effect (similar to Matrix bullet time).

I have the ring particle set to world space, so that they are left behind as the projectile moves. The renderer’s “render alignment” is set to ‘velocity’ in attempts to get the particle to rotate and align with the direction the projectile is traveling, but this does not seem to work. The particle remains ‘flat’ in its default orientation.

When “render alignment” is set to “local” the particle spawns in the correct orientation, but then continues to rotate over its lifetime.

Have also tried setting the ‘Shape’ settings “Align to direction” but this does not seem to help either.

I feel like i am missing something super simple here. It must be possible to spawn a particle with direction/ velocity at a specific rotation, and then stay in that orientation.

Any help is appreciated. Thanks.

Hi rickgplus, maybe you can check out the following settings?

  1. Set Render Alignment to Velocity.

  2. Enable module Inherit Velocity, set Mode to Initial, and set the Multiplier to a very small value e.g. 0.0001.
