Content Example - GPU Particle Collision Issue

Hello all,

This has been driving me nuts forever. I have a game I’m developing and I have some GPU particle rain and the problem is that it rains through my house. I have tried many things but here is where it gets interesting. I went into the content examples effects level 1.5 example and found that they have a GPU particle rain system essentially. Now their particles have the same kill settings as mine and in the content example level those particles will not pass through a solid object say a basic cube, but in my level they will. Here’s the kicker, I even exported the same particles from the content example level so that the settings are identical and yet in my game the particles still pass through objects. At this point it only makes sense that I have some project or world setting that is making some difference with collisions. Does anyone have any insight? Thanks.
