Batch Blendshapes

Batch operations process multiple blendShape nodes in a single pass without per-node setup.

Open both dialogs from the File menu in the main window.

Batch Export

Batch Export Blendshapes scans the scene for blendShape nodes and exports each checked node to a .deltas file in a single output directory.

Element	Description
Directory	Output folder for all exported .deltas files. Click Browse to select.
Node list	All blendShape nodes found in the scene. Each row shows the node name, a per-node Threshold spinner, and the derived output filename. Check or uncheck rows to include or exclude them.
Threshold	Per-node minimum delta magnitude. Deltas below this value are excluded from that node’s export.
All / None	Check or uncheck all rows at once.
Export Files	Exports all checked nodes to the selected directory.

Batch Import

Batch Import Blendshapes scans a directory for .deltas files, matches each to a scene mesh by filename, then imports all matches in a single pass.

Element	Description
Directory	Folder to scan for .deltas files. Click Browse to select, then Scan to populate the list.
Entry list	One row per matched .deltas file. Each row shows the target mesh, the blendShape node it will import into, the Interpolation Method with its compatibility indicator, an Apply Constraints toggle, and an All Targets button.
Interpolation Method	Per-entry method selector. The status icon confirms whether the method is compatible with the mesh’s vertex count.
Apply Constraints	Per-entry toggle. When enabled, stored correspondence constraint groups on the target blendShape node are applied after import. Only active for Index and Gradient methods.
All Targets	Shows all target names in the matched .deltas file for that entry.
Overwrite Existing Blendshapes	When enabled, any existing blendShape node on the target mesh is cleared before importing. Animation connections are preserved and restored after import.
Auto-Name Combination Nodes	Renames combination shape nodes to {Driver1}_{Driver2}_CS after import.
Import Files	Runs the import for all entries in the list.
