SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Sourcing real 3D meshes for cinematic worlds is slow and error-prone: text-to-3D providers vary in cost and quality, generated GLBs arrive with inconsistent scale and orientation, and thumbnails hide broken geometry. This Skill routes each asset need to the right provider, enforces cost discipline, and mandates Blender-based QA before assets enter a production world.

Core Features & Use Cases

  • Provider Routing: Maps asset roles to the right tool—CC0 Kenney catalogs for repeated scatter, Atlas Tripo H3.1 for text-to-3D, fal Hunyuan 3D for image-to-3D, SAM 3D Objects for multi-object reconstruction, and Blender for terrain and final assembly.
  • Cost & Provenance Discipline: Requires stating provider, model, unit cost, and output count before paid calls, and records prompts, seeds, and costs in an asset provenance manifest.
  • Mandatory Mesh QA: Inspects imported GLBs in Blender for holes, scale, ground contact, UV seams, and PBR response, with normalization to declared target heights and exclusion zones for scatter.
  • Use Case: A production needs a hero windmill plus hundreds of trees for a region. Generate the windmill via Atlas text-to-3D, pull trees from the CC0 catalog, validate both in Blender, then assemble with terrain-following scatter that respects settlement exclusion zones.

Quick Start

Use the 3d-asset-generation skill to generate a textured hero prop from a text prompt, validate the mesh in Blender, and assemble it into the world scene with provenance recorded.

FAQPage Schema
How do I generate 3D assets from text prompts for a video world?

Use Atlas Cloud's Tripo H3.1 text-to-3D model with a prompt describing one isolated object: name its silhouette, materials, art style, scale, and orientation while excluding ground planes and backdrops. Generate one sample before running a batch.

What tool should I use for image-to-3D conversion?

Use fal.ai's Hunyuan 3D v3.1 Rapid for image-to-3D when you have a concept image, since it conditions better on silhouette and style. Use a simple background and make the object occupy more than half the frame.

When should I use an asset catalog instead of AI 3D generation?

Use the CC0 Kenney catalog for repeated vegetation, rocks, and generic props because it is free, stylistically coherent, and instancing-friendly. Reserve paid text-to-3D generation for unique hero objects.

Why do generated GLB meshes look wrong after import into Blender?

Provider and catalog GLBs rarely share units, origins, or up-axis assumptions. The assembly spec declares a target_height; the renderer measures the imported bounding box, normalizes to that target, and offsets the floor to the sampled terrain height.

How much does text-to-3D generation cost with Atlas and fal.ai?

As of 2026-08-13, Atlas Tripo H3.1 costs $0.22 untextured up to $0.44 with HD textures, fal Hunyuan 3D Rapid costs $0.225 per generation, and SAM 3D Objects costs $0.02 per reconstruction. Confirm provider pages before batches since pricing changes.

Can a text-to-3D model generate an entire cinematic world in one mesh?

No. Generate hero objects individually, use licensed catalogs for high-volume scatter, and assemble everything in Blender from a semantic specification. Scene-level terrain, lighting, and cameras belong to the Blender world renderer.
