    As title suggests I got some problems with turbulence node, I cannot tame it.
    I need some deeper explanation - tool tips unfortunately were not enough.

    Also why all my particles starts going in particular direction ?
    Does working of turbulence depends on point of spawn of particle ?

    What i would like to achieve is basically particles generally traveling in a particular direction with some turbulent deviation to sides.

    Hey @koirat ,

    Not sure if you've found a solution already, but posting here in case you or anyone else finds it useful.
    There's explanation on turbulence and well as the different noise fileds it can generate on the manual here.

    Something like this perhaps? It might be a bit easier if you set the Mode to Absolute so it's not dependent on the original velocity.

    Since the generated noise field is static, particles will be have the same way at the same positions. If you'd like to change that, you can also just plug VFX Total Time into the Position or the Angle of the field transform to make it move so the turbulence will not behave the same over time.
