MeshPack analyses all Static Mesh Actors 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 Blueprints, Packed Level Actors and more. This further optimizes your game regardless of your workflow.Works with World Partition, Data Layers, Custom Primitive Data, Level Instances, preserving mesh settings and more. Further details in the docs link below.

MeshPack doesn't currently support meshes with prebuilt static lighting. I want to support this, but unsure if it's technically possible at this point.

Latest update: Version 1.4

• Fixed an issue with blueprints using AStaticMeshActor as parent being treated as pure static mesh actors
