### [Blender 5.3 Gaussian Splats: Import, Crop and Export Tested](https://digitalgarden-alicia.hashnode.dev/blender-5-3-gaussian-splats-import-crop-and-export-tested?utm_source=hashnode&utm_medium=feed)

Blender 5.3 imported 4 splat formats and preserved a crop, but native exports lost data. A 12,000-splat desktop test checks the Three.js return path.

### [Three.js Exploded View: Explode a Real Multi-Part GLB (and What It Costs in Draw Calls)](https://digitalgarden-alicia.hashnode.dev/three-js-exploded-view-explode-a-real-multi-part-glb-and-what-it-costs-in-draw-calls?utm_source=hashnode&utm_medium=feed)

Build a Three.js exploded view from a Houdini GLB. Measured draw calls, first GPU completion and click-to-isolate costs for 10 to 200 parts.
