I have a bullet I want to bounce off some solid objects but pass through others. For those objects where I don't want the bullet to bounce, I have tried disabling the solid (and collisions) on collision. But the bullet still bounces off the object once if I have the "bounce off solids" option set to yes.
I have also tried adding two bullet behaviors (on my bullet) using the method described in the post linked below (one with bounce, one without), and switching between the behaviors at the time of collision but I still find that the bullet bounces (once) off the objects I want the bullet to pass through.
