Particles stream out of sphere and rotate with sphere

#1

Hi,

So the effect I’m trying to achieve here is to have particles streaming out of a sphere/planet, and as the planet rotates, the particles rotate with it, keeping the separate streams that they are in. So, I have the particles coming out in streams like I want them , and I tried to use a lock/bond, but when the earth starts rotating, the particles go with it but don’t maintain the straight stream, they wrap around the earth. Is there a way to have the particles streaming out straight from the planet as it rotates, while the particle streams follow the planet’s rotation?

Sure there is!

Instead of using a speed operator to stream the particles out of the sphere you can control the speed and direction of the stream with a lockbond.

Duplicate your planet, I’m assuming it is a sphere/geosphere. Over the timeline animate the spheres radius/diameter. Lock/bond to surface with animated mesh checked the particles will follow the growing sphere and look as if they are streaming out.

Make sure you set the parameters animation in lock/bond to sync by particle age.

Goodluck!

Thanks,

I did this but when the planet starts rotating, the particles still wrap around it, rather than staying in straight streams. Is there a way to make the stream stay rigid or something once it has come out? So that as the planet rotates, the streams rotate with it but stay straight ?

mmmm is your sphere/planet spinning really fast or something? Lock bond seems to work pretty good on my end.

I ended up making a data op though and I think it works better than lockbond.

It’s attached. max 2014+
