Is there a way to make line particles change their path-appearance when forces (e.g. gravity) are applied?
What I’m finding is if I have a stream of particles moving horizontally, when gravity hits them the lines stay horizontal but they shout start to point down as their paths trend downwards.
Is there a fix for this? Some kind of “evaluate line direction after forces” button?

I don’t think this is possible with Action particles - I tried similar at one point. Not sure if Scott Balkom is on here, but he would most certainly know for sure.

Just found something: changing the gravity from “position” to “speed” does it.

Glad to be of service!
