Kuaishou · Kling O3 × Sketch to render
Turn hand sketches into photoreal architectural renders with Kling O3 in RenderChat. Upload your hand sketch, describe what you want, and refine the render in chat.


Drag to compare the hand sketch with the Kling O3 render. Input is an AI-generated example.
Before you start
A sketch carries the idea long before there is a model. Photograph it, tell RenderChat what the lines mean — glass, timber, trees, the time of day — and get a rendered version you can show, discuss and redraw over.
Scan the sketch or photograph it straight on in even light, then crop to the drawing.
If the pencil is light, raise the contrast so the important lines read clearly.
In your brief, say what the ambiguous strokes are: which surfaces are glass, which shapes are trees, where the entrance is.
How it works
by Kuaishou
Capture it flat, strengthen faint lines and explain the lines. The checklist above has the details.
The start button on this page opens a new chat with Kling O3 Omni Image selected. You can also pick it from the model menu in the composer.
Attach the image and say what must stay, then the materials, light, setting and people. Start from an example brief below.
Ask for changes in follow-up messages. Each Kling O3 request is sent fresh from your latest image, so repeat the constraints that matter.
Download the image at the resolution you chose (1K).
Example briefs
Copy a brief, paste it into RenderChat with your hand sketch, and change the materials and mood to match your project.
Turn this hand sketch into a photoreal render. Follow the perspective and proportions of the drawing. White brick walls, large timber-framed windows, a pitched zinc roof, a gravel path and wild grasses, soft morning light.
Render this sketch as a soft, painterly architectural visualization. Keep the linework visible, add watercolor washes for materials and sky, warm afternoon light.
