🔥(adv) FlowBuilder

🔥(adv) FlowBuilder is the same advanced flow-control node as FlowBuilder (adv) - same class, same queue panel, same batch-looping behavior - just under the display name 🔥(adv) FlowBuilder in the node menu. If you're staring at the pack's node list wondering why there are two "advanced" FlowBuilders, that's the answer: komojini registered the same class under two names with different labels, and the "(advanced)" one gets the flame-prefixed title. Don't install anything extra; they're one node wearing two hats.

So everything from the FlowBuilder (adv) article applies here. You place it before an output node - PreviewImage, SaveImage, VideoCombine - and its Queue button runs only the subgraph that feeds that output, muting everything unrelated for the duration and restoring it afterward. On top of that, the advanced panel adds three controls the plain FlowBuilder lacks:

• batch_size (INT, default 1) - run the flow this many times in sequence, each pass executing only the relevant subgraph.
• Auto Queue toggle - loop the flow continuously until you stop it. Handy for "watch this stage iterate," dangerous if you walk away.
• Disable Unrelated Nodes toggle - the master switch for the whole mute-unrelated-nodes trick. On by default; flip it off and the node just becomes a queue button that runs everything.

Plus a small status readout so you can see "2/5 Running..." rather than staring at an empty canvas.

The input/output story is minimal. Required value (*) - wire it to what your output node needs - plus optional batch_size (INT). One * output that passes value through. There is no sampling, no model work; this is control-flow plumbing. The interesting behavior is all in the UI layer.

When you'd actually use this over the plain FlowBuilder. The plain one is fine for "I changed the tail, rerun just the tail." The advanced panel earns its keep when a single stage needs to run repeatedly - generating several candidate frames or variations from one subgraph before you pick a winner, then moving on. That's the step-by-step generation philosophy the pack's README leads with ("generate images or videos step by step"), just with a repeat button bolted on.

Install. Same one-pack story:

ComfyUI Manager → search "komojini-comfyui-nodes" → Install → restart

or cd ComfyUI/custom_nodes && git clone https://github.com/komojini/komojini-comfyui-nodes. No model downloads; nothing beyond the pack's pytube/opencv requirements. The standing caveat: this is a Feb-2024 pack, and the mute/restore JS this node leans on is precisely the kind of code ComfyUI's 2025 Nodes 2.0 frontend has already broken in better-maintained packs. Verify the toggles on a scratch workflow before trusting them with a long job - and if you only need a single run, the plain FlowBuilder has fewer ways to surprise you.
