I try to figure out how they make this, any some idea how to start and make destructive trees?
Im quite new to Unreal myself but you could look into the new Chaos physics (4.26.1)fracture mode there is some good tutorials on Youtube showing how you can shoot parts of a building out , I am learning this myself so other than this I cannot offer any other advice im afraid.
Exacly i thinking about this but there no custom fracture so its very wierd effect tree destroy like concrete
