Custom ComfyUI helper nodes kept lean for tutorial use. Drop the folder into ComfyUI/custom_nodes and restart ComfyUI to load.
Flux tools
FluxSmartResize: Resize anIMAGEtensor to a Flux-safe resolution set (1M, 1.5M, 2M) with auto orientation selection and optional upscale control.FluxLatentImage: Create an emptyLATENTat a Flux-safe resolution, choosing set, orientation, and variant index; handy to feed into ksampler inputs for text-to-image.FluxPromptWithGuidance: One-stop prompt + guidance node; encodes text with CLIP and appliesFluxGuidanceso you can plug straight into the ksampler positive input.
- Copy this repo into your
ComfyUI/custom_nodesdirectory (or symlink it). - Restart ComfyUI. The nodes appear under
Arctic/Flux. - Use
FluxSmartResizeto pick and resize to a target-safe resolution before Flux conditioning;FluxLatentImageto seed your ksampler latent;FluxPromptWithGuidanceto combine prompt + guidance for ksampler inputs.
- Add new node classes to
arctic_nodes/nodes.py, register them inarctic_nodes/__init__.py. - Keep dependencies minimal; current nodes use only PyTorch (already bundled with ComfyUI) and the Python standard library.
- No external install step is required beyond placing the folder in
custom_nodes.
