Notes from real runs
Measured write-ups and working guides. Each one names the settings and the compromises, because an article that reports only the good half is an advert.

How to Convert OBJ to STL Without Breaking Your 3D Model
Converting an OBJ to STL is the easy part. What the STL loses, why conversion never repairs geometry, and what to check before the file reaches a slicer.

Why your GLB is still huge after simplifying
A measured run that cut a model's triangle count by 83% and its file size by 4.7%. The gap between those two numbers is the whole point, and it decides what to optimize next.

MeshCrunch MCP prompts: inspect, price, then optimize
Copyable prompts for driving MeshCrunch from an MCP client: reading your asset library, pricing an operation, simplifying, generating LOD chains and converting formats.

What's wrong with this 3D asset?
We ran MeshCrunch's browser-side inspection over a 92.3 MB AI-generated pug, before and after optimizing it: what it found, what it declined to measure, and what the exported report says.

Cutting a two-million-triangle model down for the web
One AI-generated pug, 92.3 MB and 1,993,980 triangles, taken through auto simplification and a LOD chain. Every number is from a real run.

When to rebuild a surface instead of simplifying it
A watertight rebuild took the same 92.3 MB pug to 19,764 triangles and 387.2 KB. What that buys, what it discards, and when it is the right trade.
