BD Blender Quad Decimate
Reduce a quad mesh using Blender's Un-Subdivide modifier. Preserves quad topology — no triangulation. Each iteration divides face count by ~4. Saves a quad OBJ for rigging/animation workflows.

Inputs (6)
| Name | Type | Default | Description |
|---|---|---|---|
| mesh | TRIMESH | — | |
| iterations | INT | 21–6 | Un-subdivide iterations. Each ~4x reduction: 1=/4, 2=/16, 3=/64, 4=/256 |
| fill_holesopt | BOOLEAN | true | Fill open boundary edges before processing |
| pre_quad_remeshopt | BOOLEAN | false | Apply Blender QUAD remesh first. Enable when input is a triangle mesh — Un-Subdivide requires quad topology. |
| octree_depthopt | INT | 73–12 | Quad remesh resolution if pre_quad_remesh=True (higher = more quads) |
| timeoutopt | INT | 30060–1800 | Max Blender processing time in seconds |
