The Edit DNA PSD node
When to use it
Adds, replaces or removes PSD correctives on a DNA, as an ordered list of operations applied atomically - a PSD is a control computed as the weighted product of its own factor controls, the missing authoring counterpart to every PSD a Get/Create DNA node can only read.
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 / Replace Factors / Remove, a Factors table (control + weight rows, Add / Replace) and, for Replace / Remove, a PSD target and a Force Cascade tick. Untick an entry to keep it staged without running it.
- 3
Press Apply PSD
Every enabled entry runs in order against the result of every earlier one. The whole batch is atomic: the first refusal publishes nothing at all, not even the operations before it.
