Hi, I've been toying around with an idea but can't seem to get it to work right. I want to place some rock models into the ceiling and on shoot or damage I want them to fall to the ground and crush anyone below. Here's what I've done so far: I've tried the same payload type of system - ie. on trigger break constraint hoping it will fall - doesn't work Also in another test for the above - rocks also seem to get stuck in the ceiling and don't fall. Rock Mass - the rocks I'm using are from forest hey have a mass of 1 so not sure if this has anything to do with hem not falling - I set the mass modifier for inertia to the same as a payload cart and it seems to fall faster but only when I used it in the fashion below. I have the rock sitting on a func_brush - on trigger, disable brush, rocks fall. I haven't been killed my the rocks yet ... I'm using a physics object. A thought that just came into my head would be to use a func_breakable and have the rock attach to that but not sure if it will fall. How do I set the damage as well? Any ideas?
