17 years old bug in A3 - 'A fallen static objects' geometries bug' in ARMA 3 - DEVELOPMENT BRANCH Posted May 9, 2018 On 04/05/2018 at 12:46 AM, oukej said: Well... the falling trees are not physically simulated - we tried that at some point early in the development but it was unsustainable on Arma scale. So they are sort of animated. And as such they wouldn't care much about physical forces. If they had collisions... Arma'd Sorry :( Collisions isn't the main problem. The gameplay issue is that fallen trees have NO viewblock for AI so they see and shoot as if nothing is there. This obviously makes it extremely frustrating to fight AI after a few trees have gone down where we cannot see them but they can perfectly attack you.
