dont worry much about it anymore, i found a workaround to lag less but still, it seemed overkill for me to get that much lag just by adding like 10 children to make a simple wall… The way i did it was using static meshes as components in the bp and make the bp replace with a delay of 0 seconds, which delays just 1 frame, each SM with the BP i want it to correspond but… It just seems like having so few children shouldnt lag that much!
