The Edit DNA Blendshape Channel node
When to use it
Adds, renames, edits LOD membership, wires an expression to, removes outright, or drops one target row of a blend shape channel, as an ordered list of operations applied atomically - the identity/wiring/removal authoring counterpart to Set DNA Blendshape, which only ever creates the inert channel from a sculpted mesh and writes its targets.
How to use it
- 1
Wire a DNA in
- 2
Build an ordered list of operations in the Operations panel below the properties
Each entry picks Add / Rename / Set Lods / Wire Expression / Remove Channel / Remove Target, a target (Channel Name, or Mesh Name + Target Index for Remove Target), and whichever of New Name / the LOD checkboxes / Control Name apply to it. Untick an entry to keep it staged without running it.
- 3
Press Apply Blendshape Channel
Every enabled entry runs in order against the result of every earlier one - rename a channel then wire it in the very next entry and the wire finds it under the new name. The whole batch is atomic: the first refusal publishes nothing at all, not even the operations before it.
