Particle gravity problem.

Support Compositing and Post Processing

I’ve arrived at an interesting situation; any suggestions on the following?

I have a sort of wall of windows set up (as one object) subdivided several times. This object has a particle system that emits the same number of particles as there are faces. In conjunction with an explode modifier and a cube with collision activated, I have this wall of windows that will “shatter” wherever hit by an object…

The problem: the particles (i.e. pieces of shattered windows) just go flying, there’s no gravity. If I set the AccZ value, all the particles start dropping at frame 1. I need them to drop only when contacted by the cube.

It’s almost like the AccZ value should be activated on a per-particle basis, when that particle is hit with a collision object.

So is there something I can do to solve the problem, or am I going about this the wrong way?

I hereby bump the thread.

Could you key frame the accz?

i.e. keep it at zero until you need it to be more?

You need to create another particle system to react for the collision / explode modifier. Here is one tutorial that should still work for 2.49. http://www.vimeo.com/1800944
