■ Overview
It is a 3D model material with rock texture that is easy to use for expressing rocky areas and caves in fantasy worlds. I hope it will be useful for shortening the time and improving the quality of background drawing.
■ Features [Terrain can be adjusted with 16 types of shape keys]
Just by moving the slider, you can easily create an uphill or downhill slope or a curve of the road. Since multiple shape keys can also be combined, it is possible to respond to various terrain variations according to the scene, such as "bends" and "undulating slopes" that are troublesome to take perspective.
[Silhouette that is easy to use even if you are close]
When used in close-up frames at the feet, the polygons are appropriately divided and smoothed so that the outer contour line does not become stuttered. You can use it without discomfort even when you close up your shoes.
【Commitment to lightness of operation】
While having as many as 16 types of shape keys, the data capacity was reduced by utilizing the normal map for fine irregularities on the surface. It has been adjusted so that even if it is placed on the canvas, the movement will not be heavy.
【Natural and realistic rock texture (Type A)】
It expresses a realistic surface with fine cracks and craggy rock surfaces spreading randomly. It is an easy-to-use design that can be used in a wide range of "rocks and rocks" scenes such as steep mountain roads, precipitous cliffs, and cave floors.
■ One-point advice when using
- Adjusting ambient light
If you keep the default ambient light settings of the CLIP STUDIO PAINT, bright areas may be a little blown out. Please adjust the intensity of the ambient light according to the atmosphere of the scene and your preference.
- Fisheye perspective reproduction technique
If you want to create an extremely distorted space such as a wide angle or fish-eye lens, try combining the shape keys "Slope" and "Bump". Dirt roads with a special perspective that are difficult to draw by hand can be easily expressed simply by adjusting the slider (GIF 1st).

■ 概要
ファンタジー世界の岩場や洞窟の表現などに使いやすい、岩の質感の3Dモデル素材です。背景作画の時短やクオリティアップに役立てていただければと思います。
■ 特徴 【16種類のシェイプキーで地形を調整可能】
スライダーを動かすだけで、上り坂・下り坂（Slope）や、道のカーブ（Curve）などを簡単に作ることができます。複数のシェイプキーを組み合わせることもできるため、パースを取るのが面倒な「曲がり角」や「うねりのある坂道」など、シーンに合わせた様々な地形のバリエーションに対応可能です。
【寄りでも使いやすいシルエット】
足元の接写コマなどで使用した際に、外側の輪郭線がカクカクしてしまわないよう、ポリゴンを適切に割って滑らかにしています。靴元のアップなどでも違和感なくお使いいただけます。
【動作の軽さへのこだわり】
16種類ものシェイプキーを持たせつつも、表面の細かな凹凸はノーマルマップを活用してデータ容量を抑えました。キャンバス上に配置しても動作が重くなりづらいよう調整しています。
【自然でリアルな岩の質感（Type A）】
細かなひび割れや、ゴツゴツした岩肌がランダムに広がるリアルな表面を表現しています。険しい山道や断崖絶壁、洞窟の床面など、様々な「岩・岩場」のシーンに幅広く対応できる使い勝手の良いデザインです。
■ ご利用時のワンポイントアドバイス
- 環境光の調整について
CLIP STUDIO PAINTのデフォルトの環境光設定のままだと、明るい部分が少し白飛びしやすい場合があります。シーンの雰囲気やお好みに合わせて、環境光の強度を調整してご使用ください。
- 魚眼風パースの再現テクニック
広角や魚眼レンズのような極端に歪んだ空間を作りたい時は、シェイプキーの「Slope（傾斜）」と「Bump（隆起）」を組み合わせてみてください。手描きでは難しい特殊なパースの未舗装路も、スライダーの調整だけで簡単に表現可能です（GIF1枚目）。
