Particle system(force over lifetime node)

Discussion in 'General Graphics' started by MTUA, Mar 28, 2020.

?

The simulation space setting is broken and the lin between world space and local space is blurred.

    The simulation space option in the force over lifetime node doesn't work properly. I tried making a tornado completely from the shuriken particle system. But the axis of rotation for angular velocity kept shifting with the main parent particle system transformation rather than the position of the parent particle.

    I would use the orbital velocity settings in the velocity over lifetime module, to make a tornado.

    If you think there is a bug in unity, shown by your current setup, please report a bug and we will take a look.

    Thank you. I don't come onto the forums a lot. I thought I had to do all that in order to post.

    The whole local space world space business is also present in shader graph for certain effects.

    I thought this was where you go to report bugs?

    “Thread tools” or “edit” button or something. But it doesn’t really matter about deleting it :)

    Do you think it's possible for a cling function to be added to th shuriken particle system?

    Can you describe what it would do in more detail?

    Like the way water would cling to your wind screen when it rains.

    Basically a normal force function under collision.

    I don't know if "normal force" is the name to call it. But you get my point, right?
