title: "Directional Sprites stills: render a 3D model as it is (no animation) into one large image per direction, in a style, on a transparent background. Pass the GLB in `model` (URL or base64), the `directions` (up to 8, rendered together so they line up) and the style (listDirectionalSpriteStyles). Each still is a sprite image you can animate with animateSprite or edit with editImage. The job result is one image per direction, in the order asked. Credits are held for every direction when the job is accepted and charged for the images that come back; a failed or cancelled job is refunded. Pass an optional request_id to tag the images for later retrieval via listGenerations (type image). Requires an API key (user scope). The call returns 202 with a job id - poll getApiJob (pass wait 30 to long-poll) honouring poll_after_ms, until status is succeeded; its result field is exactly the response documented for this operation. Synchronous responses are deprecated but still supported: pass `async: false` to block until the result is ready and receive it as the response body. Synchronous calls run on the same queue: the response carries an X-Ludo-Job-Id header, and a job still running after 15 minutes comes back as 202 with the job instead of an error. Each account may have up to 50 generations queued or running at once via the API; a request beyond that returns 429 (code PENDING_JOBS_LIMIT)."

`POST /assets/sprite/directional-stills`

## Request

- Base URL: `https://api.ludo.ai/api`
- URL: `https://api.ludo.ai/api/assets/sprite/directional-stills`
- Auth: API key in header `Authorization`

## Request body

- DirectionalStillsPayload: Payload for rendering a 3D model as one still image per direction
  - `model` string, required: The 3D model, as a URL or base64-encoded GLB file (not an AI model name). Rendered as it is, in its rest pose. Up to 30MB; a larger file is rejected with HTTP 400.
  - `perspective` 'horizon' | 'low' | 'isometric' | 'high' | 'top': Camera height, from the side (horizon) to straight down (top).
  - `directions` string[]: Where the camera stands around a character facing S, each direction at most once. One image per direction, in this order, rendered together so they line up.
  - `style_id` string: A style id from listDirectionalSpriteStyles.
  - `style_version` integer: Version of the style; omit for its current one.
  - `style_params` object: The style's settings to change, by name, each one of its listed option values (true/false for a bool setting, or any colour for a color one). Omit a setting to keep its default.
  - `request_id` string: Optional client-provided identifier, unique per request. Re-sending the same request_id returns the existing job instead of generating again. Also usable as the request_id filter of listGenerations.
  - `async` boolean: Defaults to true: the call returns 202 immediately with a job id to poll with getApiJob. Set false for a synchronous response (deprecated but supported): the call then blocks until the result is ready.

## Response `200`

Success

- DirectionalStillsResult
  - `images` DirectionalStill[]: One image per direction, in the order asked.
    - `direction` string: The direction this image is seen from.
    - `url` string
    - `width` integer
    - `height` integer
    - `render_3d` DirectionalSpriteRender
      - `style_id` string
      - `style_version` integer
      - `style_params` object: The style's settings as rendered, by name.
      - `perspective` string
      - `direction` string
      - `animation_name` string
      - `fps` number, float
      - `keep_horizontal_travel` boolean
      - `keep_vertical_travel` boolean

## Other responses

- `202`: Accepted - the generation was queued; poll GET /assets/jobs/{id}. A synchronous (async: false) call still running after 15 minutes also receives this.
- `400`: Error
