P.S. * Added a tip item about LT conversion that can be seen by scrolling to the bottom (for those who wanted to use it in monochrome but are worried about extra lines)
If you change the contour width line, the impression will change quite a bit. The photo below is outline width 10.
If you set it to Not affected by the light source, it will look clean like the following.
There is only one half-daifuku in the cross-section, but if you duplicate it, rotate it, and rearrange it, you can do something like this.

Textures are hand-drawn in CLIP STUDIO
Matcha Daifuku with realistic cross-section! Low-poly hand-drawn texture for smooth performance in Clip Studio. Perfect for manga food illustrations! By turning off 'Receive light source influence', the model gets a clean and flat appearance like in the thumbnail sample!
P.S. * Tips for monochrome conversion using LT conversion
It is recommended to turn off the light source setting before extracting etc. (it is easier to come out cleanly).
That way, it will be easy to come out cleanly even with LT conversion, etc. If you don't want to pick up the black line to the ingredient part, I think that gradation should be turned off and set to tone center ◇ The following explanation
■ Since this material is a round sphere + handwritten texture, extra lines may be picked up depending on the light source settings during LT conversion. So when converting LT, turn off ◆ extract after posterization ← setting ◆ After turning off the texture extract line ← setting You can output beautifully by adjusting the tone intensity as you like.

追記※下までスクロールしていただけば見れるLT変換についてのコツの項目を追加しました(モノクロで使いたかったけれど余計な線がでてお悩みの方用)
輪郭幅線を変えると印象が結構かわります 下の写真は輪郭線幅10です
光源の影響を受けない に設定にしたら以下のようなようなスッキリした見た目になります
断面の半分大福は一つだけですが 複製して回転 配置しなおすと こういうこともできます

追記※LT変換を使ってモノクロ化する場合のコツ
光源の設定をOFFにしてから 抽出等を行うことをお勧めします(そちらのほうがきれいに出やすく簡単です)
そうすればLT変換等でもきれいに出やすいです 具の部分まで黒の線を拾うのが嫌な場合は階調化はベタの項目をOFFにされてトーン中心に設定されるといいと思います◇以下解説
■この素材は丸い球体+手書きテクスチャなので、LT変換時に光源の設定によっては余計な線を拾ってしまう場合があります なのでLT変換時に◆階調化してから抽出←設定をオフ ◆テクスチャのライン抽出←設定をオフにしたのち お好みでトーンの濃さを調整すればきれいに出力はできます
