Ok, so this is a little complex. I have a system where I generate a sky-scraper type building by placing a destruction mesh a certain number of times above itself. This is done with a loop that adds the mesh a random amount of times as seen here:
here I am generating the number of floors and each time I add one I reduce the number of floors left to create (simple stuff). Now, every time this runs I get a different sized building. The building looks ok and is destructable. The problem is when I destroy a lower section pretty much all sections above it hover in the air (a few exceptions when I force them to collide but that doesn’t matter) I have tried everything. I have applied physics at pretty much every oppurtunity, I have enabled gravity, I have forced the pieces to intersect so when one of them updates it forces the one above to fall. I have a feeling it may has something to do with them being awake but because of the way it is set up I can’t set them to always awake. One thing I tried for a while was to set it so when a lower piece fractures it forces damage on the above pieces but the fracture was never triggered. I am out of ideas and so is the internet apparently. Any help?
