View Full Version : Consistent gravity question & instancing question

Just playing around with ICE this morning and I'm having trouble understanding how/why the gravity force affects my emitted particles the way it is.

Right now I'm just emitting particles from some polygons. I want them all to be emitted with a constant velocity and have gravity affect them in the exact same way. I'm using instanced geometry for the particles.

I have a gravity force plugged into the force node. The particles all have a size of 1 and a mass of 1. But as the particles fall, 99% of them fall consistently and there are always 2-3 that seem to just float around.

If I remove gravity and just use velocity, they fall fine, but gravity doesn't seem to be applied consistently.

The other issue is with instanced geometry. I've noticed that checking "hide instance master" causes all instanced ICE particles to disappear. Is there a different way to hide the instance master in ICE?

Thanks,

Paul
