(deforum) Logical OR

Two Boolean inputs, one Boolean output, true if either input is true. That's DeforumOrNode in one line - the smallest "either of these" gate in the Deforum logic toolkit.

It exists because animation graphs grow branches fast. "Apply this effect if we're past frame 150 or if the audio level is high." "Use the video's motion if hybrid is on or if the seed is even." Comparators hand you single conditions; this node stitches two of them together so one true result is enough to trigger a switch.

Inputs and output

• condition_1 and condition_2 - two BOOLEAN inputs, from any source.
• BOOLEAN - true when either (or both) inputs are true.

Standard truth table, no surprises. Wire it into a switch, an Image Switcher, or another logic node and the graph starts behaving like a program instead of a straight line.

Pairing it with the pack

It's the natural companion to the other logic nodes: Logical NOT inverts a branch, FLOAT Comparator and the INT comparator produce the raw conditions, and OR combines them. A typical chain looks like Comparator → OR → switch, and once you're comfortable with that shape you'll find yourself building multi-condition behavior that would otherwise require duplicating whole subgraphs.

Installation

Ships with Deforum Nodes:

cd ComfyUI/custom_nodes
git clone https://github.com/XmYx/deforum-comfy-nodes.git

Restart ComfyUI, or grab "Deforum Nodes" by XmYx from ComfyUI Manager. Pure logic - no models, no backend dependencies beyond the pack itself, works even mid-install.

Gotchas

Honestly, there's almost nothing to get wrong. One habit worth forming: keep the two conditions obvious in your own head - condition_1 and condition_2 are just labeled A and B, and when you revisit a workflow in a month, a switch_prompt_after_120, is_hybrid_active style chain reads far better than anonymous wires. The node won't do it for you.

If you never need it, fine - but the moment you find yourself thinking "this should happen if X or Y," this is the node.
