Utility nodes for ComfyUI.
Where to find the nodes
These nodes are local (in your custom_nodes folder). They do not appear in ComfyUI-Manager's install list.
To use them: right-click canvas → Add Node → Cornman-Utils, or search by node name.
Nodes
Resolution Picker
Picks a random width and height from a set of resolution pairs.
Each row has:
- Toggle (green ✓ / red ✕) — enable or disable that pair
- Width × Height — editable number inputs
- Delete (−) — remove the row (hidden when only one pair remains)
- + Add Resolution — add a new pair at the bottom
Seed controls which pair is chosen (same seed → same result).
Outputs: width (INT), height (INT) — connect to Empty Latent Image or similar.
