View Full Version : For all the "Thinking Particles" gurus out there

Hey all,

I'm having some issues with motion inheritence.

Basically, I have a deforming mesh that is being used to "hold" a group of particles (ie...they stick to the surface) for a certain amount of time, and then at a particular frame they fall off.

The trouble I'm having occurs when they fall off....when they move to the next group that contains the gravity spacewarp (allowing them to fall off), they fall straight down, and don't inherit any of the motion that the swinging object they were attached to had.

Ideally, I would like them to fly off...similar to the way mud would fly off a boot if you were to shake it.

Any ideas? I guess I'm just wondering how to tell the next group to inherit the motion of the last group.

Found the solution.

I was using a position operator to set the particles position once that was determined by the surface pos helper. The problem though is that the position operator doesn't seem to transfer velocity/speed values to the next event.

So instead I used the position follow operator, and that one does seem to pass on velocity/speed values.

Just ran into the same problem myself and the guys on the cgfluids came up with a very smart solution - yours sounds a much simpler solution which I like right now :)
