About scenario-skyboxes

scenario-skyboxes is a Scenario skill for generating seamless 360 panoramas with dedicated skybox models and upscaling them without breaking the wrap. It is for creators building environment backdrops, with guidance on model discovery, iteration, and export.

Key features

  1. 01Discover skybox models
  2. 02Inspect model parameter schemas
  3. 03Generate and iterate on 360 panoramas
  4. 04Upscale while preserving the seam
  5. 05Preview and export assets

Use cases

  1. 01Create panoramic game environments
  2. 02Guide skybox composition with reference images
  3. 03Upscale a skybox and check its seam

MCP support

It uses Scenario MCP tools to search models, inspect parameter schemas, run generation jobs, and display or download resulting assets.

Install

Copy the command and run it in a terminal.

$npx skills add https://github.com/scenario-labs/skills --skill scenario-skyboxes

From the project README

Scenario Skyboxes and 360 Panoramas

Overview

Scenario hosts dedicated skybox models that produce seamless equirectangular 360 panoramas, plus a seam-preserving skybox upscaler. Always generate with a skybox-specific model rather than a generic image model: these enforce the seam continuity and pole geometry that ordinary text-to-image output lacks.

Connection and the core generation loop: see the scenario skill in this repo. If a sibling skill named here is missing from your available skills, ask the user to install it (npx skills add scenario-labs/skills --skill <name>); unattended, proceed from tool schemas and flag the gap.

Quick reference

Model IDs and the parameter facts below were live search hits at authoring time. Re-discover them each time: availability differs per team and evolves.

  • model_scenario-skybox-flux: text to 360 panorama, a style preset enum (count drifts; read it from the schema), automatic seam and pole correction, optional reference image with a strength slider.
  • model_scenario-skybox-gpt: text to 360 panorama guided by up to 10 reference images, quality presets, width and height up to 3840 px.
  • model_hunyuan-world-image-to-skybox: one photo of a place to a seamless 360 skybox.
  • model_sc-upscale-flux-skybox: 2x to 8x skybox upscale that preserves the seamless wrap.

Worked example: generate, iterate, export

Example: a stylized forest skybox for a game scene.

  1. search with target="models", query="skybox", public=true. Pick a text-to-skybox model, for example model_scenario-skybox-flux.
  2. model_schema_get for that model. Expect fields like prompt, style, negativePrompt, image, strength, numOutputs, geometryEnforcement, seed. negativePrompt is inert unless negativePromptStrength is above 0.
  3. model_run with parameters={"prompt": "ancient pine forest at dawn, mist between trunks, god rays", "style": "cinematic", "numOutputs": 2}. Take style preset names from the schema response. dry_run=true first prices the run; launch with wait=false.
  4. jobs_wait with job_ids=[the returned job_id]. Its ~180s timeout is not an error: re-call with the returned pending_job_ids as job_ids, never a second model_run. Then asset_display each output.
  5. Iterate on mood: copy the seed from the best result and change only style (cinematic, oil-painting, cyberpunk, and more). To keep composition while shifting look, pass the favorite as image with low strength (0.2 to 0.4). To steer mood from concept art instead, switch to model_scenario-skybox-gpt and pass referenceImages.
  6. Export: run model_sc-upscale-flux-skybox with image=asset_id and the smallest upscaleFactor that reaches target (the upscale can cost several times the generation, and its dry_run can only run once the input asset exists, so the chain cannot be priced up front). baseModel defaults to FLUX.1-dev (stylized); a Krea-based realism option exists, and strength defaults to 0.6, which invents detail: lower it when the goal is the same panorama at higher resolution. Read the exact allowed values from model_schema_get before switching. Then asset_download the final asset.
  7. Verify the seam at no cost: compare the saved PNG's leftmost and rightmost pixel columns; on a seamless panorama they differ by near zero while columns a quarter-turn apart differ by an order of magnitude more.

Engine format notes: Skybox Flux outputs equirectangular panoramas; keep the default sizing (1536x768 at authoring time) and read the real dimensions off the returned asset rather than assuming them. Skybox GPT's catalog lists equirectangular 2:1 plus cubemap strip 6:1 and cubemap cross 4:3 layouts, but its schema exposes only width and height, so confirm the layout contract with model_schema_get before relying on a cubemap layout. Beyond flat backdrops, the same search surfaces model_hunyuan-world-skybox-to-splat, and a separate search (query="world") finds the Marble world models; both turn a finished panorama into a navigable 3D Gaussian splat scene, the pipeline the scenario-3d-worlds skill teaches end to end.

Common mistakes

  • Prompting a generic image model for a "360 panorama": edges will not wrap and poles smear. Use a dedicated skybox model.
  • Upscaling with a generic upscaler: it breaks continuity at the wrap seam. Use the skybox upscaler.
  • Hardcoding model IDs in scripts or docs: re-discover with search; the catalog changes.
  • Fighting seam or pole distortion through prompt wording on Skybox Flux: raise geometryEnforcement above 0 instead, and only when distortion is actually visible.
  • Requesting a non 2:1 width to height ratio on Skybox GPT while expecting equirectangular output: keep 2:1 (for example 2048x1024) for correct 360 viewing.
  • Skipping model_schema_get: skybox models carry model-specific fields (style, geometryEnforcement, quality) that generic assumptions miss.
