# Assets / Create Material

## How to Call

```bash
unity-mcp-cli run-tool assets-material-create --input '{
  "assetPath": "string_value",
  "shaderName": "string_value"
}'
```

> For complex input (multi-line strings, code), save the JSON to a file and use:
> ```bash
> unity-mcp-cli run-tool assets-material-create --input-file args.json
> ```
>
> Or pipe via stdin (recommended):
> ```bash
> unity-mcp-cli run-tool assets-material-create --input-file - <<'EOF'
> {"param": "value"}
> EOF
> ```

### Troubleshooting

If `unity-mcp-cli` is not found, either install it globally (`npm install -g unity-mcp-cli`) or use `npx unity-mcp-cli` instead.
Read the /unity-initial-setup skill for detailed installation instructions.
