Speed up scene optimization and reduce tedious manual work with DrawCall Doctor.

DrawCall Doctor is a smart, non-destructive optimization assistant for Level Designers, Environment Artists, and Indie Developers working in Unreal Engine 5. It helps identify compatible Static Mesh actor groups and applies the most suitable optimization workflow using HISM or Native Merge — while keeping your original actors backed up for later restoration.

Instead of manually deciding when to use instancing or merge workflows, simply select your actors and let DrawCall Doctor analyze them for you.

Key Features

Smart Analysis
Automatically analyzes selected Static Mesh actors and recommends the best workflow:

• HISM for identical compatible meshes

• Native Merge for compatible mixed props

• warnings and exclusions for risky actors such as Nanite, Translucent, Additive, and WPO-based materials

Non-Destructive Workflow
Original actors are preserved in a backup workflow so you can safely optimize without permanently losing your editable scene setup.

Restore Originals
Need to make changes later? Select the optimized actor and restore the original backed-up actors when needed.

Detailed Before / After Report
Review a clear optimization report with actor counts, draw-call estimates, and geometry information before committing to the optimization.

Scene-Wide Scan
Use the toolbar scan feature to inspect your level and identify potential optimization opportunities across compatible actor groups.

Built for Practical UE5 Workflows
Designed for developers targeting performance-sensitive projects, especially for mobile, VR, and other scenes where reducing actor and draw-call overhead matters.

Important Notes

• Results depend on scene content and actor compatibility.

• This tool focuses on Static Mesh optimization workflows.

• Risky or unsupported actors may be excluded automatically for safety.

DrawCall Doctor helps simplify scene optimization, reduce repetitive manual work, and keep your workflow flexible.
