Unreal Texture Management
Use this Skill to audit and optimize Unreal Engine textures for package size, cooked disk size, runtime memory, streaming stability, and visual quality.
Workflow
Identify the user's actual symptom: package size, VRAM/runtime memory, streaming hitching, blurry textures, or import/organization hygiene.
Read references/texture-management.zh-CN.md before recommending texture changes.
Separate package-size fixes from runtime-only fixes. r.Streaming.PoolSize can reduce over-budget streaming pressure, but it does not shrink cooked packages.
Inspect real project settings before changing advice: texture assets, Config/DefaultEngine.ini, Config/DefaultScalability.ini, platform DeviceProfiles, and packaging cook rules.
Prefer reversible bulk-edit plans: audit top offenders first, then change MaxTextureSize, LODGroup, LODBias, compression, mip generation, sRGB, channel packing, or source asset resolution.
Rebuild texture streaming data after material/mesh/UV changes, then recook/package before claiming package-size wins.
Validate in editor and cooked build with texture stats, streaming stats, package size comparison, and visual spot checks.
For MCP-assisted bulk work, use the scripts in scripts/. They default to dry-run and require explicit -Apply before saving texture assets.
路由
For asset naming, Content folder organization, bulk asset moves, import conventions, or Texture2D asset creation, use ../orion-asset-management/SKILL.md.
For render config placement, DefaultScalability.ini, video settings, DLSS/TSR interactions, or project rendering policy, use ../orion-rendering-framework/SKILL.md.
For exact CVar lookup such as r.Streaming.*, r.VT.*, sg.TextureQuality, or runtime/startup editability, use ../unreal-render-commands/SKILL.md.
For package, cook, staging, IoStore, or Steam build-size validation, use ../orion-packaging/SKILL.md.
For Unreal source confirmation, engine version differences, or property/module ownership, use ../unreal-source-code-navigator/SKILL.md.

Scripts
scripts/mcp-audit-textures.ps1: read-only audit for large Texture2D assets under explicitly provided folders.
scripts/mcp-cap-max-texture-size.ps1: dry-run or apply a fixed MaxTextureSize cap, such as 4K-or-larger textures capped to 2K.
scripts/mcp-half-by-lod-bias.ps1: dry-run or apply LODBias += 1 to approximate half-resolution cooked/runtime mips.
scripts/mcp-half-by-max-texture-size.ps1: dry-run or apply MaxTextureSize = current long edge / 2.
scripts/mcp-set-texture-lod-group.ps1: dry-run or apply a LODGroup assignment so DeviceProfile/TextureLODGroups can manage the group.
scripts/mcp-fix-compression-and-srgb.ps1: dry-run or apply heuristic Normal/Mask/Color compression and sRGB fixes.
scripts/mcp-enable-virtual-texture-streaming.ps1: dry-run or apply VirtualTextureStreaming for very large texture candidates.
scripts/mcp-plan-lodgroup-config-no-uasset.ps1: read-only group distribution report for no-uasset config strategies.
