Particle trail and deflectors
show user profile  yosoyelmacho
So I'm doing a laser cutting animation, where sparks fly out where the laser hits the metal. It's still a work in progress, but one of the problems I'm having I cant seem to fix.
The sparks are particles subject to gravity, which leave stationary trails behind them, which fade over time, I have a Material Dynamic with a Particle Age material applied to make them go white->red->out. The trajectory particles also collide with a Deflector (the floor) and bounce up with some fraction of the velocity.
My problem is, that the trail the particles leave behind cuts off when they bounce off the ground. More specifically, right *before* they bounce. Its like if a particle is above the surface one frame, and bounces and moves up in the next frame, only the trail coming up is created, no trail going down.
Perhaps this picture will clarify:
I've tried turning on Subframe Sampling on the Position icon, but there is no such option for the Spawn switch, which is what I have making the particles. Any suggestions?
This is all in Max 2010, and I am not using any plugins
