# Gallery starters

Public Model 4 scenes from the Skybox AI Gallery (opens new window). Each row is a starter you can open in the app, plus the equirectangular JPG to send as a remix source. Use them to test Remix in an application without generating a source first.

Opening a starter page or a JPG does not spend credits. A remix request does.

# Remix a starter

POST https://backend.blockadelabs.com/api/v1/skybox with header x-api-key. Paste any row’s API image into control_image.

This request remixes Eucalyptus bushfire haze in Open World (Model 4), Balance quality, on the Softlines path (Retain structure in the web app). The layout of the starter stays. The style and the prompt change the light and mood.

{
  "skybox_style_id": 155,
  "prompt": "The same woodland at foggy dawn, orange sun gone, cool mist between the trees.",
  "negative_text": "people",
  "control_image": "https://images.blockadelabs.com/skybox-starters/158_3ab4125d980b3a20f922699b0d30b812_file.jpg",
  "control_model": "remix",
  "soft_lines": true,
  "variant_id": 1
}

155 is Open World. variant_id 1 is Balance (3 credits). control_model must be "remix". soft_lines: true is Softlines. soft_lines: false is Depth. Swap control_image for any other API image below. Deep space nebula is the exception on style: use skybox_style_id 224.

Model 4 styles require a Standard or Business plan. Write the prompt as one or two sentences. Put unwanted subjects in negative_text. Prompting · Model 4 · Remix settings.

init_strength is the Model 3 color dial. A Model 4 remix of a starter uses control_image, as in the request above.

The viewer loads the eucalyptus JPG from that request. Drag to look around. It does not call the API. Open the viewer.

# Sample packs

Game, Visualization, and Studio packs are not available yet. Each pack will be a PNG preview and an EXR per scene. The packs do not include a depth file. Until the packs ship, use the JPG links in the library for an API remix test.

# Library

Each row includes:

  • Viewer — the title opens the starter in Skybox AI
  • Prompt — the text under the title
  • API image — equirectangular JPG for control_image

Two High desert plateau scenes differ: mesa edge and open plateau. Two Canyon red rock noon scenes differ: layered cliffs and rim. Two Vineyard hills haze scenes share a title and are separate images.

The prompt under the title matches the image. On Monsoon rice terraces, Greenhouse botanical, and Wasteland junk town, the prompt returned with the skybox does not match the picture. Those three rows use the catalog prompt.

The live set is in Gallery (opens new window). EXR files will be in the sample packs when those packs are available.
