Trailer: Watch.
InstanceForge is an Unreal Engine editor plugin for converting repeated Static Mesh actors and components into clean, optimized ISM and HISM layouts.
It helps reduce unnecessary actor and component overhead in production scenes by scanning repeated meshes, previewing optimization candidates, and building organized instance clusters with reversible build history.
InstanceForge is designed for modular environments, duplicated props, kitbashed scenes, Marketplace demo cleanup, and editor-side level optimization workflows.
KEY FEATURES
• Scan selected actors, the current level, or InstanceForge volumes
• Detect repeated Static Mesh groups across your scene
• Preview build candidates before modifying the level
• Estimate draw call impact before building
• Build Single ISM, Split ISM, or HISM layouts
• Smart Auto layout selection with ISM-first logic
• Per-group target layout overrides
• Include and exclude scan volumes for controlled optimization areas
• Build history tracking
• Restore original actors and components when needed
• Designed for real Unreal Engine editor production workflows
SMART AUTO LAYOUT SELECTION
Smart Auto helps choose between Single ISM, Split ISM, and HISM layouts for each detected mesh group.
It is designed to prefer simpler ISM layouts first and only use HISM when it clearly makes sense for the group. You can also override the selected layout per group before building.
SAFE AND REVERSIBLE WORKFLOW
InstanceForge is built around a safe editor workflow:
• Scan your scene
• Review detected mesh groups
• Preview optimization candidates
• Choose layouts manually or with Smart Auto
• Build optimized instance clusters
• Restore originals from build history when needed
This makes it easier to test optimization passes without permanently committing to irreversible level changes.
GOOD FOR
• Modular environments
• Repeated props
• Large kitbashed scenes
• Marketplace demo cleanup
• Level optimization passes
• Editor-side instance conversion workflows
• Reducing repeated Static Mesh actor/component overhead
IMPORTANT NOTES
InstanceForge is an editor optimization workflow tool.
Actual performance gains depend on scene structure, mesh repetition, materials, visibility, LODs, renderer settings, hardware, and target platform.
Always test important production levels under source control or on a copy of the map before running major optimization passes.
