Load ConDelta

ApplyConDelta loads a saved delta and adds it to a conditioning in one step - convenient, but it also means you're locked into that node's specific add-and-strength behavior. LoadConditioningDelta does only the first half: it loads a saved ConDelta from disk and hands it back as a plain CONDITIONING output, with no addition, no strength, nothing else attached. What you do with it after that is entirely up to you.

Why you'd reach for it

Once you're past the "just apply the delta" stage, you often want more control than ApplyConDelta gives you - clamp it first with ClampConDelta or HardClampConDelta, scale it with ConditioningScale, average it with another delta via ConditioningAverageMultiple, or feed it into ConditioningAddConDeltaAutoScale for the normalized-strength version of applying it. All of those nodes want a plain CONDITIONING as input, not a file path - this node is the bridge between your saved deltas and the rest of the pack's live-conditioning toolkit.

How it works

You pick a file from the condelta dropdown, and the node loads it and outputs it as-is, unmodified.

The inputs and outputs that matter

• condelta - a dropdown populated from your ComfyUI/models/ConDelta folder. Same tooltip quirk as ApplyConDelta and ApplyConDeltaAutoScale - it says "The name of the LoRA," which is a leftover from wherever the author copied the file-picker code. It's not loading a LoRA; it's loading a ConDelta file.

Output is a single CONDITIONING - the raw, unmodified delta.

How to install it

Via ComfyUI Manager: search "ComfyUI-ConDelta", install, restart. Manually:

cd ComfyUI/custom_nodes
git clone https://github.com/envy-ai/ComfyUI-ConDelta

Then set up the shared model folder that all the file-based nodes in this pack need:

1. Create a folder named ConDelta (case sensitive) inside ComfyUI/models.
2. Copy the files from custom_nodes/ComfyUI-ConDelta/sample_models into it, or drop your own saved deltas there via SaveConditioningDelta.
3. Restart ComfyUI.

Common issues & troubleshooting

Empty dropdown means the folder isn't set up. If condelta shows no options, ComfyUI/models/ConDelta either doesn't exist or is empty - the same issue you'd hit with ApplyConDelta or ApplyConDeltaAutoScale, since all three read from the same folder.

This node alone does nothing visible. Unlike ApplyConDelta, loading a delta here doesn't apply it to anything - you still need to route the output into an add node (ConditioningAddConDelta or its AutoScale sibling) before it affects a generation. If you just want the one-step version, use ApplyConDelta instead.

Deltas are tied to the model family they were built from, same as everywhere else in this pack - a delta loaded here still needs to end up applied to a conditioning from a compatible architecture, or the result won't mean much.
