Particles disappearing in animations

[metalmario01]

The particle systems in my animation never show up when I do a final render of it. Any idea why? When I do a static final render of a frame, the particles draw. If I do an animation immediately after starting on the same frame I just rendered the particles will show for that frame in the animation but no others.

Wow! This forum really is dead... The only reason I've been using E3D was because it's what my school uses. Anyway, I've found that the vanishing particle systems seem to occur only when the emitter's characteristics (ie. position, on/off, strength, etc.) change during tha animation. It seems possible that these changes are simply not updated when a final render is conducted. Looks like a simple bug in a dead program... -_-
