description	Use when users want to optimize textures, meshes, or improve performance.

Optimization Skills

Overview

Optimize project assets (Textures, Models).

Common Mistakes

DO NOT (common hallucinations):

• optimize_scene / optimization_run do not exist → use specific skills: optimize_analyze_scene, optimize_find_large_assets, optimize_find_duplicate_materials, etc.
• optimize_compress / optimize_compress_textures / optimize_compress_meshes / optimize_compress_audio do not exist → use optimize_textures (textures), optimize_mesh_compression (meshes), optimize_audio_compression (audio)
• optimize_set_lod / optimize_setup_lod do not exist → use optimize_set_lod_group
• Optimization skills are analysis + action tools — always review results before applying batch changes

Routing:

• For profiler metrics → use native Unity_Profiler_* tools (see ../../mcp-tools.md)
• For static batching flags → optimize_set_static_flags (this module)

Skills

optimize_textures

Optimize texture settings (maxSize, compression). Returns list of modified textures.

Parameter	Type	Required	Default	Description
maxTextureSize	int	No	2048	Max texture size
enableCrunch	bool	No	true	Enable crunch compression
compressionQuality	int	No	50	Compression quality 0-100
filter	string	No	""	Asset filter

Returns: { success, count, message, modified }

optimize_mesh_compression

Set mesh compression for 3D models.

Parameter	Type	Required	Default	Description
compressionLevel	string	No	"Medium"	Compression level: Off/Low/Medium/High
filter	string	No	""	Asset filter

Returns: { success, count, compression, modified }

optimize_analyze_scene

Analyze scene for performance bottlenecks (high-poly meshes, excessive materials).

Parameter	Type	Required	Default	Description
polyThreshold	int	No	10000	Triangle count threshold for high-poly warning
materialThreshold	int	No	5	Material slot count threshold for excessive materials warning

Returns: { success, totalRenderers, totalTriangles, totalMaterialSlots, issueCount, issues }

optimize_find_large_assets

Find assets exceeding a size threshold (in KB).

Parameter	Type	Required	Default	Description
thresholdKB	int	No	1024	Size threshold in KB
assetType	string	No	""	Asset type filter (e.g. Texture2D, AudioClip)
limit	int	No	50	Maximum number of results

Returns: { success, threshold, count, assets }

optimize_set_static_flags

Set static flags on GameObjects. flags: Everything/Nothing/BatchingStatic/OccludeeStatic/OccluderStatic/NavigationStatic/ReflectionProbeStatic

Parameter	Type	Required	Default	Description
name	string	No	null	GameObject name
instanceId	int	No	0	GameObject instance ID
path	string	No	null	GameObject hierarchy path
flags	string	No	"Everything"	Static flags to set
includeChildren	bool	No	false	Apply to all children recursively

Returns: { success, gameObject, flags, affectedCount }

optimize_get_static_flags

Get static flags of a GameObject.

Parameter	Type	Required	Default	Description
name	string	No	null	GameObject name
instanceId	int	No	0	GameObject instance ID
path	string	No	null	GameObject hierarchy path

Returns: { success, gameObject, flags, isStatic }

optimize_audio_compression

Batch set audio compression. compressionFormat: PCM/Vorbis/ADPCM. loadType: DecompressOnLoad/CompressedInMemory/Streaming

Parameter	Type	Required	Default	Description
compressionFormat	string	No	"Vorbis"	Audio compression format: PCM/Vorbis/ADPCM
loadType	string	No	"CompressedInMemory"	Audio load type: DecompressOnLoad/CompressedInMemory/Streaming
quality	float	No	0.5	Compression quality 0.0-1.0
filter	string	No	""	Asset filter

Returns: { success, count, compressionFormat, loadType, modified }

optimize_find_duplicate_materials

Find materials with identical shader and properties.

Parameter	Type	Required	Default	Description
limit	int	No	50	Maximum number of duplicate groups to return

Returns: { success, duplicateGroups, groups }

optimize_analyze_overdraw

Analyze transparent objects that may cause overdraw.

Parameter	Type	Required	Default	Description
limit	int	No	50	Maximum number of results

Returns: { success, transparentObjectCount, objects }

optimize_set_lod_group

Add or configure LOD Group. lodDistances: comma-separated screen-relative heights (e.g. '0.6,0.3,0.1')

Parameter	Type	Required	Default	Description
name	string	No	null	GameObject name
instanceId	int	No	0	GameObject instance ID
path	string	No	null	GameObject hierarchy path
lodDistances	string	No	"0.6,0.3,0.1"	Comma-separated screen-relative transition heights

Returns: { success, gameObject, lodLevels, distances }
