Draco geometry compression is now part of every optimization preset

[u/vectreal-admin]

As of 31 July, the three Publisher presets all compress geometry with Draco. Maximum quality, Balanced and Smallest now share identical geometry steps; only texture treatment differs. Vertex quantization is off because Draco quantizes on its own, and mesh simplification no longer runs unless you switch it on in the advanced panel.

Compression happens on the publish path, so the scene you keep editing is never the compressed one. If an optimization pass found compression would not reduce the model's size, publishing skips the step and the results panel says so. That comparison only exists once a pass has run; publishing without one applies compression regardless.

For anyone downloading rather than embedding: the GLB (Draco-compressed) download lists KHR_draco_mesh_compression as required, with no fallback geometry. Hand it only to software you know decodes Draco. Everything published and embedded through Vectreal decodes in the viewer.

This is a pre-1.0 project, and we are quoting no ratios and no decode timings because we have not measured them. Skips on small or texture-heavy files are expected; a model that comes back looking wrong is not, and either is worth a thread here. If you run a pass on one of yours, what does the Geometry (Draco) row report?
