I’ve created a test blend to change a sphere into a suzanne.
There are two particle systems on the sphere;
- Emit outward without gravity
- Explode modifier to carry the surface of the sphere as chunks.
The suzanne also has a static particle system as a destination.
The 2nd system on the sphere is keyed, firstly to the emitter, then the suzanne particle systems.
So far so good… and looks great over 250 frames.
I want the keyed particles (and the bits of geometry they are carrying) to disappear over the last 10 frames or so so I can use a build modifier on the suzanne to make it look like the disappearing stuff is making up the monkey.
I can’t seen to get the keyed particles to end over a period of time like a normal particle system does.
I’ve tried setting the keyed and the suzanne particle lifetimes to 240 with a start/end of 1/5, but they persist beyond this.
