🆕 Added
Blender 4.2 is now fully supported — one archive for 4.2–5.0. Verified on 4.2, 4.5.11 LTS and 5.0.1.
Recalculate + Smooth — a checkbox added to the Light version, on the Very Aggressive modes, with an adjustable Crease Angle. Builds normals from the simplified geometry instead of carrying the source ones, which no longer match it at very low triangle counts (meshoptimizer, experimental).
🐞 Fixed
Shading of imported models. Their normals were sometimes read as flat shading with custom normals, which caused serious trouble when simplifying the model.
An empty LOD could be added silently. At a high Target Error, Prune can delete every disconnected part of a mesh. Such a level is no longer created, and the report says which ones were skipped.
The importance mask on a Very Aggressive Alternative level lost that level entirely. The mask reaches the Decimate pass through a temporary vertex group, and cleaning that group up afterwards raised an error which took the finished mesh with it.
⚡ Faster
~15% faster generation — Merge by Distance runs on the buffers, so the mesh is born welded.
