description: Create a new Material asset with default parameters at a given 'Assets/'-rooted path ending in '.mat'. Creates intermediate folders if missing. Use 'assets-shader-list-all' to find a valid `shaderName`.

# Assets / Create Material
|
|
|
|
Create new material asset with default parameters. Creates folders recursively if they do not exist. Provide proper 'shaderName' - use 'assets-shader-list-all' tool to find available shaders.
|
|
|
|
## Inputs
|
|
|
|
- `assetPath` — must start with `Assets/` and end with `.mat`.
|
|
- `shaderName` — name resolvable via `UnityEngine.Shader.Find`.
|
|
|
|
## Behavior
|
|
|
|
Throws if the path is empty, malformed, or the shader cannot be resolved. Creates a default Material from the resolved shader, saves it, refreshes the AssetDatabase, and returns an `AssetObjectRef` pointing at the new asset.
|
|
|
|
## 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.
