Description
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, PLA, Blueprints 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 2.0
- Reworked the plugin from the ground up to more robust and handle edge cases better
- Missing usage flags on materials now gives a warning in the Output log instead of showing up gray in the packaged game
- Fixed an issue with PLAs having ISMs marked as movable
- Sorted the components so that transforms close together ends up in the same ISM
- Physics settings are now copied from the original mesh to the ISM
- Meshes with custom vertex colors are now correctly ignored
