When models is have 238 objects and u are using folders in blockbench plugin to it etc. then u are gain limit of folders. Theres no info about it on chat and u have limits with folders. If u remove folders then it works, please fix it i want to made HighPoly models safely and faster than now.

Also, if u remove the folders and have rotation maded by folder for cubes then it not render models for others.

P.S bug is only on Multiplayer
