recommended you, develop a mod + plugin version of the model loading engine, to fix garbage overhead performance problem, create mod to client for rendering and loading, without affecting the server performance.
transcend limitations, It is obvious that the bottleneck of pure plug-ins has appeared. Don't be obsessed with bottleneck creation and development.
Otherwise, no matter whether this project is in Meg 3-4, when applied to multi-player team BOSS challenges, the player's skill model special effects and the Meg engine's model operation will always destroy the performance of the server.
