Niagara: Rotate particle around an axis while moving

Technical & Engine Help
#1

Hey all,

I have been racking my brains about how to make this work in a niagara effect. Feels like it should be simple.

I want to have a particle orbit around a given axis and at the same time be moving forward, so in the end its moving forward but spiraling around the given axis.

I got something that looked right using rotate around point but its not giving me reliable results, if I increase the spin speed its going crazy. Anyone got any advice on this problem? or a better way of doing it :stuck_out_tongue:

Also it seems to be stable in the preview window but not in my scene…

Maybe this helps. I use a scratch pad module in Niagara to create a custom rotator based on the axis I need. Leader emitter must be in Local space. Here is the setup.

Rewire the split position vector node to the 2D rotator based on your project.
