x402
Rengi Forge GLB LOD Chain Generator is a paid API for AI agents from rengi.dev, paid per call via x402, $0.2/call, status unknown (last checked 2026-10-22).
Generates a multi-level LOD chain from a GLB file with locked UV borders, producing one optimized GLB per level, a side-by-side render, and Unity LODGroup transition heights

How this service works
GLB optimizer: Generate a LOD chain from a GLB (default 100/50/25/10% of triangles) with locked borders so UV seams and silhouettes hold; one GLB per level, a side-by-side render and Unity LODGroup transition heights. Full schema: https://rengi.dev/v1/glb-optimizer/schema
Output
Returns one optimized GLB file per LOD level (matching the requested ratios), a side-by-side render image comparing all levels, and Unity LODGroup transition height values ready to paste into a Unity project. Each GLB has its open edges and UV seams preserved due to border locking.
Example use cases
Unity game character LOD setup
“I have a character GLB at https://cdn.mygame.com/hero.glb — generate a full LOD chain at 100/50/25/10% triangles with locked borders so the UV seams don't shift, and give me the Unity LODGroup transition heights so I can drop it straight into my scene.”
Web3D asset polygon budget reduction
“Can you take this GLB from https://assets.studio.io/prop_tree.glb and create LOD levels at 100%, 50%, and 25% triangle counts with border locking on? I need individual GLB files for each level for our WebGL renderer.”
Custom LOD ratios for mobile game
“Optimize this GLB model at https://storage.mobiledev.com/vehicle.glb into a 4-level LOD chain using ratios of 100%, 40%, 15%, and 5% to hit our mobile polygon budgets — keep the borders locked and give me a side-by-side render so I can sanity check the quality.”

Endpoint
POSThttps://rengi.dev/v1/glb-optimizer/lod?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need game-ready LOD levels from a GLB with UV seam and silhouette integrity preserved — particularly for Unity workflows where LODGroup transition heights are needed out of the box. Prefer this over generic mesh-decimation tools when UV correctness and border locking are critical, or when you need all LOD levels generated in a single API call rather than running separate decimation passes manually.
Side effects
- Invalid or unreachable GLB URL returns an error with the HTTP status of the fetch failure
- GLB file is malformed or not a valid glTF binary — returns parse error
- Ratios array has fewer than 2 or more than 6 entries — schema validation error
- Ratio values outside 0.01–1.0 range — validation rejection
- Model has no triangles or is a point cloud — decimation cannot proceed
- File too large for processing within timeout — timeout or size limit error
