Collada → GLB

Collada (DAE) to GLB, flattened and optimized

Zlim converts Collada (.dae) — the verbose XML interchange format exported by Blender, SketchUp, and Unity — into a single optimized GLB, typically 70–80% smaller, with the scene graph flattened and geometry Draco-compressed.

Why convert Collada to GLB?

Collada is an open XML format, which makes it portable but slow: files are large, slow to parse, and often carry deeply nested scene graphs and duplicated geometry from the exporting tool.

GLB is a binary container that parses fast and ships as one file — the format real-time runtimes actually want.

What Zlim optimizes

Zlim flattens redundant scene-graph nodes, instances or de-duplicates repeated geometry, quantizes and Draco-compresses meshes, and transcodes textures to KTX2. Merging compatible meshes also lowers the draw-call count that a naive DAE export tends to inflate.

bash

zlim optimize scene.dae -o scene.glb -p balanced   # → scene.glb (≈75% smaller)

FAQ

My DAE came from SketchUp / Blender — is that supported?

Yes. Zlim targets the common Collada profiles those tools emit and normalizes them into a clean GLB.

Are materials and textures preserved?

Yes — materials map to glTF PBR where possible, and referenced textures are bundled into the GLB and transcoded to KTX2.
