# オブジェクトをマスク
現在、茂みは地形全体に広がっており、望ましくありません。代わりに水が自然にたまるこのような乾いた地形では川の脇に制限します。そのために、川レイヤーをオブジェクトレイヤーの分布にドラッグします。これにより **リバー・ディストリビューション** がそのレイヤーに自動的にリンクされます。また、 **川の範囲** を0に、 **谷の範囲** を1に設定します。茂みが川自体に現れることを避けたいからです。
ご覧のとおり、これにより川の周りに非常に狭いマスクができます。これを変更するために、 **谷幅** を5にして、茂みを配置できるより広い谷を作ります。
その上で、今度は **ブラー** エフェクトを追加してさらに滑らかにし、茂みを散らすための広い領域を与えます。

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.
Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:
```
GET https://docs.world-creator.com/ja/wkusur/obujekutowo/obujekutowomasuku.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
