IPAdapter Mad Assistant V1

IPAdapter Mad Assistant V1 is the same slider-to-string helper as the base node, with one difference that changes what it's for: the twelve layer Weight sliders run -1.0 to 1.0 instead of 0.0 to 1.0. You get the ability to go negative on any of the 0–11 layers.

Why would you want negative? Setting a layer to -1.0 doesn't just turn the reference image off on that layer - it pushes against it, actively subtracting the image embedding's contribution. The practical use is when a style transfer keeps dragging the composition or when one specific layer reads too hot and you want to suppress it rather than simply zero it. The community mostly lives in the 0..1 range; negative values are the "turn this off, and then some" move. If a generation is over-lifting structure, dropping an early layer into the negatives is often what actually fixes it.

Everything else is the base node. It builds the layer:weight comma string (output layer_weights, STRING), you convert Mad Scientist's layer_weights widget to an input and wire it up, and Random mode works the same way - except the random fill now draws from -1.0 to 1.0 instead of 0 to 1, so random runs can quietly zero-invert a layer. The seed input is declared but never used in the code, so random mode stays unreproducible.

Which one do you want?

Honest answer: the base node, 90% of the time. V1 earns its keep when you've identified a layer that's too present - composition fighting you, or one style band dominating. Keep your daily workflows on the 0..1 node and drop in V1 when you need the subtraction.

One README trap worth knowing: the pack's README credits V2 as the "-1 to 1" variant. It isn't - per the shipped code V1 is -1..1 and V2 goes to -2..2. If a workflow you downloaded mentions the "gentle negative" version by the wrong number, this is the one.

Install

Shared with the whole pack - it's the same single-file repo:

cd ComfyUI/custom_nodes
git clone https://github.com/11dogzi/ComfUI-EGAdapterMadAssistant

Restart ComfyUI, or search ComfUI-EGAdapterMadAssistant in ComfyUI Manager. No pip, no dependencies, no model downloads. You still need ComfyUI_IPAdapter_plus and its models for anything to render.

If the output does nothing, check that you converted Mad Scientist's layer_weights widget to an input before wiring it - that's the failure mode that looks exactly like a broken node.
