Watch a visual novel cast made in Ludo

Ivy, Rowan and Professor Hale from one recipe in the Watercolor style, every expression with Edit with Mask and a new outfit with Edit Image, then a greenhouse background, a dialogue box and a name plate put together in a Ren'Py scene.

Transcript: How to Make Visual Novel Sprites with AI (Consistent Cast, Every Expression, Ren'Py Scene)

Rowan: Late again, Ivy.

Ivy: I was out picking lavender. For you, actually!

Rowan: For... for me?

Every image in this visual novel scene, the cast, every face, the background and even the dialogue box, came out of ludo.ai.

Here's how to make your own, start to finish.

Open the Image Generator, keep Generation Mode on Generate New, and pick the Sprite type, so she comes back cut out on a transparent background.

In Filters, set Art Style to Watercolor, a soft painted look that suits a visual novel, and Aspect Ratio to Portrait 9:16, so there's room for the whole figure.

The prompt is a recipe: her name and who she is, hair and eyes, the outfit, one prop, and standing and facing the viewer, full body.

Generate, and pick the take you'd happily look at for a whole game.

Ours came out like this.

Ivy: Obviously, this one.

For the rest of the cast, keep every setting and the same recipe, and only change the person.

Giving them the same academy cloak helps them read as one cast.

Rowan: It looks better on me.

Now the expressions.

Open Generation Mode, the menu that also holds Edit Image and Upscale Image, and pick Edit with Mask.

Choose her sprite, press Draw Mask and paint over her face, then describe the new one: angry, frowning, cheeks puffed in a pout.

The mask limits the edit to the painted area, so her hair, outfit and pose stay where they were, and the sprite doesn't jump when her mood changes.

One description per mood: happy, angry, sad, surprised, flustered and smug, then a few more for Rowan and Professor Hale.

Hale: I do not do flustered.

For clothes, switch to Edit Image and write it out: change only her outfit to a summer festival yukata, and keep her face, hair and pose.

We did the same for a pose, hands on hips for her confident moments.

Backgrounds come from the Static Background type, in the same Watercolor style at Landscape 16:9: an empty greenhouse, painted edge to edge, so the cast can stand in it.

Even the dialogue box and the name plate are Ludo images, from the UI Element type at a wide aspect ratio, already on transparent backgrounds.

For a crisp full-screen scene, Upscale Image raises the resolution.

Download each one, it saves as a PNG, and put the sprites in your Ren'Py project's images folder, named by character and mood, like ivy angry.

A script line that says show ivy angry swaps her face on that line, and the box and the plate go in the gui folder, with a few style lines from the pinned comment.

Here's the scene in Ren'Py.

Hale: Both of you. Inside. Now.

Ivy: Professor Hale?!

Rowan: I'm not!

常見問題


  • 共 32 種風格,包括 8-bit 與 16-bit 像素藝術、卡通、動漫/漫畫、Q版、手繪、水彩、扁平設計、低多邊形、體素與黏土動畫風。


  • 可以。用一張風格參考圖生成,新角色就會沿用它的配色、線條粗細與比例。


  • 會,角色會匯出為透明 PNG,內建去背功能,可直接放進你的遊戲引擎。


  • 可以。用動作提示詞、手繪關鍵影格、參考影片或 641 種預設動作中的任一種,為任何角色製作最長 5 秒、最多 64 影格的動畫,Hydra 動畫還會附上相符的音效。你也可以上傳自己的角色圖片來製作動畫。


  • 可以。Change Pose 能把角色改成新姿勢,它的 Change View 模式能把角色轉到 8 種鏡頭角度中的任一種;New Direction 則會把完成的動畫朝新方向重新算圖,動作與節奏維持不變。如果角色各方向必須完全對齊,Directional Sprites 能從同一個綁好骨架的 3D 模型算出最多 8 個方向,提供 15 種風格,可以從文字描述或你自己的角色圖片開始。


  • 歸你所有。你用 Ludo 生成的角色屬於你,可以隨意使用,包括用在商業遊戲中。
