What's the difference between an asset sheet and a key frame?

An asset sheet (often orthographic, neutral lighting, plain background) is built for a 3D artist to model from, so clarity beats drama. A key frame is a cinematic, atmospheric illustration meant to sell a mood to a director. Pick the perspective and lighting to match which one you need.

How do I get consistent designs across multiple images?

Lock the wording for genre, style and subject and only vary the angle or lighting between runs. Reusing the same seed (where the model supports it) and referencing a previous image keep proportions and the design language consistent.

Should I include a turnaround or callouts?

For production hand-off, ask for an orthographic turnaround (front, side, three-quarter) on a neutral background. The builder includes this when you choose the asset-sheet perspective, which is what a modeller needs to work from.

Is anything I type uploaded?

No. The builder assembles text in your browser only. Nothing you enter is sent to a server, stored or logged.

Concept Art Prompt Builder

Concept art prompt builder

Concept art has a job to do: communicate a design clearly enough for a director to approve it or a 3D artist to build it. This builder turns a subject, genre, style, perspective and lighting mood into a production-style prompt for Midjourney, Stable Diffusion or any image model — whether you need a clean asset sheet or a cinematic key frame.

How it works

The builder maps each subject type to the framing professionals use. Vehicles get clean silhouettes and mechanical detail callouts; creatures get anatomy, silhouette read and texture; environments get scale, atmosphere and a sense of place; weapons get material breakdown and ergonomic detail. The perspective choice then decides the deliverable: an orthographic turnaround on a neutral background for modelling, or a cinematic three-quarter key frame for mood. Genre, style and lighting layer the world and the emotion on top.

Tips and notes

Asset sheet vs. key frame: choose orthographic + neutral lighting when a 3D artist will model from it; choose cinematic + dramatic lighting when you’re selling a mood.
Stay consistent across a set. Keep the genre/style/subject wording fixed and vary only angle or lighting; reuse the seed where you can.
Describe materials, not just shapes. “Brushed titanium and worn leather” gives a modeller far more to work with than “metal.”
Iterate in passes. Block the silhouette first, then re-roll with added detail words once the overall read is right.
