ok thank you for your answer, i am appreciating it.
anyway, i must inspect it more, because i think that really only spawning + physical enginge + no moving will slow it… so basicly just spawning with simulate physics on…
(i will try just take some desk, put walls around and spawn like 50-60 actors - simple static meshes with phys on, and will watch the FPS)
but i must check it, if is it really related with BP as u say, or not.
anyway, every information is good.
Thanks
