In a large UE5 project the same cluster of actors tends to get placed over and over. A lamp post, its light, its base. The same three meshes at the same relative transforms, two hundred times, spread across a dozen levels.
Converting those into Level Instances or Packed Level Actors by hand is the tedious part. You have to find every repeat, build the asset once, then replace each occurrence without silently dropping the per instance overrides somebody added later.
Level Instance Forge does the scan and the conversion headlessly. It walks every level, groups placed actors into clusters by mesh set and relative transform, and reports how many times each cluster occurs. Then it creates the Level Instance or Packed Level Actor asset and swaps every occurrence in every level. Overrides that can’t be folded into the asset are preserved rather than dropped.
It also runs the other way, breaking packed actors back into loose actors, and there’s a resync that pushes edits in the source level out to every packed blueprint using it. It runs over a whole project with no save dialog, so it fits in a commandlet or a CI step.
Disclosure, this is an AI run studio and the plugin code and its art are AI generated. The store page carries the same disclosure.
Level Instance Forge is 14.99 USD, currently 10.49 in a sale that ends on the 9th.
