    Hi

    I made an ok hyperspace tunnel using the regular particle effects and wanted to see if I could make a better one with VFX Graph.
    The old particles had velocity over life with orbital settings.
    I can't work out how to duplicate that with VFX, so any help/guidance would be much appreciated.

    Cheers

    Try applying force based on the cross product of the current direction. It's something like that anyway.

    Please forgive me...I have no idea what a cross product is, therefore no idea how to base anything on one :(
    I have messed about with all the force nodes though. I imagine i will have to lump together some nodes that do some magic maths calculations.

    care to share and shoe the result?
    I am struggling too to get ribbons to swirl, im not sure what i should be using to get the particles circling around a point /axis.
