Performance of "Simulation Generates Hit Events"

Hello Sjoerd!

So to make things short. I have an arrow that’s flying. Naturally, a flying arrow, when hitting a tree, will in most cases stick to it. When hitting a rock it will either break or bounce off of it.

But in order for it to be aware of what it’s hitting, both the arrow and the hit object needs to have “Simulation Generates Hit Events” ticked. Which takes more performance, especially if I have this activated on say all of the trees, the ground, and everything else that an arrow will stick to.

Maybe there’s a better way?


Perhaps a good alternative would be to drive that parameter as you move around the scene.


Pretty sure this is your parameter? I have not actually played with it yet.
