Tinkering? You mean, find anything by myself? (My english sucks )
Well, last sunday, i try to learn particle emitter by my self (with a bit help from WILL's tutorial) i found that i can stop and starting effects using animate visibility (the integers)
then i make i simple fireball missile with only stand and death animations, no geosets, when it plays the death animation in game, it loops
i already check the unlooping flag, not working
about creating geosets, i dont have the tools unless oinkerwinkle vertex modifer, maybe you can teach me some?
