InstanceForge

InstanceForge is an Unreal Engine editor plugin for converting repeated Static Mesh sources into optimized ISM and HISM instance components.

It is built around a safe workflow: scan first, review the Build Plan, build with recoverable source handling, inspect generated results, then benchmark and restore when needed.
