Unity Importer Skills

Change the import settings of textures, audio and models already in the project. Parameters come from the schema (`GET /skills/schema?category=Importer&wire=v2`); execution and dryRun rules: root [SKILL.md](../../SKILL.md). Extended helpers, field meanings and presets: [reference/import-reference.md](reference/import-reference.md).

When to use

• Adjusting how textures, audio or models import
• Setting texture compression or sprite modes
• Applying per-platform overrides, or rig and animation clip splits

Rules

• Batch first: use the `*_batch` setters when configuring 2 or more assets of one category.
• Getters and finders run in every mode. Setters and reimports need a grant under Approval.
• No skill here deletes or reloads the domain. Setting changes do not always apply in memory at once: call `asset_reimport` or `asset_reimport_batch` after changing importer-critical fields.
• `compression` takes `Uncompressed`, `Compressed`, `CompressedHQ` or `CompressedLQ`; Inspector wording is accepted. Per-platform `compressionQuality` is a separate 0-100 integer.
• `sprite_set_import_settings` forces `textureType` to `Sprite` for `Single`, `Multiple` and `Polygon`.
• `animationType` `Human` is also accepted as `Humanoid`.

Pitfalls

• Texture `format` values depend on the editor version: read `validValues` on a rejection.
• Platform overrides apply only when `overridden` is enabled.
• After `model_set_rig` or `model_set_animation_clips`, reimport so clips and avatar refresh.

**DO NOT** (common hallucinations):

• `importer_import` does not exist: use `asset_import` (`asset` module).
• `importer_set_format` does not exist: use the category setters.
• `importer_get_settings` does not exist: use the category getters.
