MetaMeshmizer is a powerful batch optimization plugin for Unreal Engine that automatically reduces static mesh triangle counts and downsizes textures used in their materials, helping you boost performance, cut memory usage, and keep visual quality under control with minimal manual work.
What Does MetaMeshmizer Do?
MetaMeshmizer focuses on two core editor tools:
Batch Static Mesh LOD Reduction
Reduce triangle/vertex counts across entire folders of static meshes, with automatic LOD generation and Nanite support where appropriate.Batch Texture Resize
Scan all static meshes in selected folders, find the textures referenced by their materials, and batch shrink those textures to a chosen percentage of their original resolution.
Key Features
Folder Based Batch Processing
Run both mesh and texture optimization from:Tools → Static Mesh Tools in the main editor menu, or
Right click Content Browser folders via custom context menu entries.
Smart Auto Perform Mode
Let the plugin automatically:Decide whether to enable Nanite
Choose an appropriate LOD Group (SmallProp, LargeProp, LevelArchitecture)
based on each mesh’s post reduction triangle count and bounds radius. This mode overrides manual Nanite/LOD Group choices to give you consistent, data-driven optimization.
Configurable Mesh Reduction
Set a Reduce Percent to control how aggressively triangles are removed.
Optionally enable Nanite, tune Nanite fallback Keep Triangle %, and choose LOD Groups when not using Auto Perform.
Control additional options like Support Ray Tracing, Distance Field Scale, and Allow CPU Access for advanced workflows.
Automatic LOD Chain Generation
When Nanite is disabled and LOD Group is set to None, MetaMeshmizer generates up to 6 progressive LODs, each at 50% of the previous one, starting from your chosen reduction for LOD0. When a LOD Group is used, only LOD0 is adjusted and the group rules manage the rest.Texture Aware Optimization
Collects all textures referenced by static meshes (material slots, material instances, texture parameters).
Avoids duplicates and resizes each unique texture by your chosen Reduce Percent (e.g. turning 2048×2048 into 1024×1024 or 512×512).
Preserves original formats, sRGB/linear settings, and compression options.
Clear Progress Feedback
Both tools provide a progress window with folders, asset counts, and live status so you always know what’s being processed.
Technical Details
Type: Editor only optimization plugin
Supported Platforms: MetaMeshmizer is designed to operate on Windows.
Usage Context:
Works inside the Editor (not available in packaged builds).
Designed for projects that need fast, repeatable optimization passes across many meshes and textures.
Core Dependencies (Modules):
Core, CoreUObject, Engine
UnrealEd, EditorSubsystem, AssetRegistry
ContentBrowser, ToolMenus
MeshUtilities, MeshReductionInterface
Ideal Use Cases
Preparing levels for performance-critical platforms by quickly reducing overall triangle and texture budgets.
Cleaning up asset packs you’ve imported that ship with extremely high polycounts and oversized textures.
Creating consistent LOD and Nanite setups across different environment sets (props, architecture, large structures).
Automating repetitive optimization steps late in production or before profiling passes.
Part of the Meta System
MetaMeshmizer is part of the Meta family of tools by Asha Empire Team, focused on making Unreal Engine workflows faster, more automated, and more developer friendly. It is designed to sit alongside other Meta plugins as your go to batch optimizer for static meshes and textures.
Why MetaMeshmizer?
Instead of manually opening each mesh or texture and tweaking settings one by one, MetaMeshmizer lets you:
Select folders
Choose a few parameters
Hit OK and let the plugin process everything for you
If your project is starting to struggle with draw calls, memory usage, or loading times due to heavy assets, MetaMeshmizer gives you a fast, controllable way to bring everything back into a reasonable budget, without sacrificing more visual quality than necessary.
