Merge Modular Actors/Assets?

Hey guys
I built a modular castle with thousands of pieces, each 5x5 floor tile, walls, and …
it all has only one material and, in some cases a total of 3 with no vertex painting. so do I need to merge like every 20-floor tile next to each other and walls and … for optimization?
I don’t want to change any of the specific material on any of them.

Hey @MHKakooei!

If you’re not using Nanite, then yes, you do want to merge them to reduce calls as much as possible without merging the entire thing together. Think room by room, any static meshes can be merged, and you can leave things like chairs etc. separate!

Hope that helps!

Nanite meshes can be merged also, but you need to disable the nanites on meshes you want to merge. Then you can enable nanites on the merged mesh.
