Hi!
I’m very proud to announce MeshPack! The plugin makes instancing of meshes super easy and artist friendly!

It analyses all Static Mesh Actors in the level and packs them into instances when the game is packaged.
No need to manually combine actors while you are working on your game.

It works with World Partition and normal levels, making your workflow nondestructive and highly optimized. MeshPack also re-packs Packed Level Actors. This further optimizes your game regardless of your workflow.

Check it out on the Marketplace! https://www.unrealengine.com/marketplace/meshpack

Example case with Valley of the Ancient project
Large open world level with thousands of meshes. Used to showcase UE 5.0 with World Partition and Packed Level Actors.

Blueprint support is coming along nicely! :smiley:

Great job mate! Unreal should have natively support instancing like this. When you will have proper BP support, I’ll start recommending your pack with my stuff as a superior to PLA.
Take care!
