# FAQ.4 — Maya が接続できないとき、点検ログを送る

## 概要

Maya が SkinLayer Studio に接続できないときは、下の点検スクリプトを実行し、出力をすべてメールで送ってください。  
スクリプトは読むだけです。インストール、ファイル削除、コネクタ起動はしません。

送信先: [contact@otakusolutions.com](mailto:contact@otakusolutions.com)

今すぐ作業を続ける必要がある場合は、[FAQ.3 — 強制起動](../faq03-maya-force-start/) でコネクタをオンにできます。原因の確認にはこのログが必要です。

---

## メールに書いていただくこと

1. SkinLayer Studio のバージョン（Help → About）
2. Maya のバージョン
3. コネクタ導入後に Maya を完全終了して開き直したか
4. 下のスクリプト出力の **すべて**。最後の `VERDICT` を含む
5. 可能なら SkinLayer Studio 上部の DCC 欄の画面

シーンファイルとライセンスキーは送らないでください。

`sessions` フォルダは自分で作らないでください。そのフォルダはコネクタが起動したときにできます。空のフォルダでは接続されません。

## 実行方法

1. Maya で **Windows → General Editors → Script Editor** を開きます。
2. 下の入力欄で **Python** タブを選びます。MEL ではありません。
3. 下のスクリプトを **すべて** 貼り付けます。
4. 選択を外して **Ctrl + Enter** で実行します。一部だけ選択すると `Invalid Code Fragment` になることがあります。
5. 出力をすべてコピーしてメールに貼ります。

SkinLayer Studio の `</>` ウィンドウでは実行しないでください。

```python
from __future__ import print_function

# SkinLayer Studio - Maya connection check
# Windows > General Editors > Script Editor > Python tab > paste all > Execute.
# Do not run this inside the SkinLayer Studio window.
# Read-only: it does not install, delete, or start the connector.
