Description
Immersive Cleaning is an underrated mod. It uses the same method that the game developers used to clean The Castle after certain Minutemen quests. Every object that is to be cleaned has an enable parent set to a marker inside the settlement. To clean the settlement the mod disables the marker which instantly disables every object to be cleaned. Simple!
The objects to be cleaned are part of the previsibines by default. Immersive Cleaning has regenerated previsibines so the objects can be cleaned but normal performance is retained. However, the regenerated previsibines have issues which lead to flickering problems in Sanctuary.
Previsibines Repair Pack is a project to rebuild all of the games precombined meshes and occlusion (previs) information which have many problems by default. There are versions of the patch for current PRP branch 74 and the older branch 69, select the correct version when downloading. The patch fixes all previsibine faults found in Immersive Cleaning. I used PJM's Precombine - Previs Patching Scripts to create the patch, which are used to create PRP itself.
