asset-transformer-toolkit — Claude Code skill: 3D imports
This skill guides Unity workflows for bringing in 3D models and point clouds, then working with RuleSets, Actions, and LODs. Use it with Asset Transformer Toolkit or Pixyz.
npx skills add Unity-Technologies/skills --skill asset-transformer-toolkit -a claude-codeWhat asset-transformer-toolkit does
The skill helps an agent handle files brought into a Unity project from outside it, configure ImporterScriptableObjects, and work with RuleSets, Actions, and LODs. Its references cover the related workflow steps and APIs. Importer fields are handled through the ScriptableObject API rather than reflection.
The project needs com.unity.industry.toolkit version 4.0.0 or later, since earlier releases lack an API used by the skill. If the package is missing, the agent is instructed to stop; an older version calls for user approval before an upgrade. Reimporting can take a long time, so the skill leaves that step for an explicit request.
What it helps with
- bring an external 3D model into a Unity project
- create or edit an ImporterScriptableObject
- configure a RuleSet and its rules
- set up LODs for a model
- reimport a model when requested
Example prompts for the agent
- Import this 3D model into my Unity project using Asset Transformer Toolkit.
- Check the
com.unity.industry.toolkitversion and configure an importer for this model. - Create a RuleSet to process this model and set up its LODs.
