SM World Optimizer is an open-source tool designed to improve the performance of large Scrap Mechanic worlds by removing unnecessary and scattered objects that accumulate over time.
The goal of the tool is to restore the world to a usable and stable state when save files grow excessively large and performance degrades — even on high-end PCs.
