LoRA Loader

Applies a whole stack of LoRAs to a model (and optionally CLIP) from one compact node. Each row is one LoRA: an on/off pill, a searchable picker, and strengths you can drag like a slider. Trigger words from every enabled row come out of one socket, ready to wire into a prompt.

Rows

• grip (the dotted handle): Drag up or down to reorder the stack. LoRAs apply in row order, so the order is part of the recipe; the move commits when you drop, and a cancelled drag changes nothing.
• toggle: Enable or disable the row without losing its settings.
• name: A plain click opens the picker — type to search, Arrow Up/Down to highlight, Enter to select, Escape to close; the list is refreshed from models/loras every time it opens. Dragging left/right on the name instead scrubs the model strength, and the bar behind the text rides along. Rows show just the file name by default; the full path lives in the tooltip and the picker keeps its folder groups.
• strength: Drag left/right on the number to scrub it, click to type an exact value, use the chevron arrows, or the arrow keys. Hold Shift while scrubbing or stepping for fine 0.01 moves. Range is -10 to 10.
• i: Info card with the preview image, base model, file size and modified date, and trigger words for that LoRA.

Right-click a row to move, duplicate, or remove it. One strength drives both model and CLIP by default; the gear menu's Separate model / CLIP strength switch shows a second box per row. The switch is per-node — new nodes always start unified — and an absorb that imports a row with unequal model/CLIP strengths flips it on automatically so the difference stays visible.

Strength bars

Every named row paints a center-zero bar behind its name: teal grows right of center for positive model strength, muted red grows left for negative, a 1px tick marks zero and a brighter 2px cap marks the value's edge. One shared scale across the stack: the field edges represent the largest absolute strength among the enabled rows, floored at 1.0 — so an everyday stack of 0.5s reads absolutely as half-bars, one row at 2.0 rescales every bar rather than clipping, and switching that row off hands the scale back to the strongest row still in play (the dimmed row's own bar clamps at the edge meanwhile). The scale in play is named in each row's tooltip. Gear menu → "Strength bars" turns them off; "Scrub strength on the name" turns the name-drag off.

The control bar

The bar rides the empty middle of the output-slot band, so the node spends its height on rows, not chrome. Left to right:

• ▤ templates — save the current stack under a name, or apply/delete a saved one. Templates are shared across workflows.
• master pill — cycles mixed → all on → all off → back to the mixed setup it destroyed. Every hand-made row toggle refreshes that memory, so an accidental master click is always one more click from home.
• summary — how many rows are on.
• ↻ reconnect — re-checks every row against a fresh models/loras list and repairs what it can: a row whose file moved folders (or came back after being missing) is rewritten to the resolved path. ComfyUI's own R refresh runs the same pass quietly.
• ⚙ gear — settings, and the Absorb chain LoRAs action below.

+ LoRA sits inside the stack container, pinned to its bottom edge.

Absorb the loader chain

Gear menu → Absorb chain LoRAs. Walks the model chain on BOTH sides of this node — upstream through the model input, downstream from the model output — and for every loader it recognizes (LoraLoader, LoraLoaderModelOnly, Power Lora Loader (rgthree), PixaromaLoraLoader, another AusBoss LoRA Loader; Reroutes are walked through) lifts its rows into this stack — appended below your existing rows, upstream loaders first in chain order, then downstream — and sets the original nodes to bypass. The graph keeps computing exactly what it did, from one node (LoRA patches accumulate, so row order does not change the math).

Details that keep the absorb faithful:

• names are resolved against this install's models/loras — exact match first, then a unique basename match ignoring folders and extension (for workflows saved on another machine's layout); unresolved names import verbatim and the rows tint red
• LoraLoaderModelOnly rows import with CLIP strength 0
• a LoRA already in the stack is skipped, not doubled; the dedupe spans both directions
• already-bypassed or muted loaders contribute nothing but do not stop the walk; a fan-out (the model output feeding more than one node) stops the downstream walk, because bypassing a loader there would change what the other branches compute
• a toast summarizes what was imported, bypassed, remapped, and skipped

Moved and missing files

Rows are checked against the install's LoRA list. A row whose file moved folders gets a dashed border and a tooltip naming the file the run will use; a row with no match anywhere tints red; an ambiguous basename tints red with advice to re-pick. Thumbnails, the info card, and range lookups all use the resolved name, so a moved file keeps its previews and Civitai data.

The run side matches: a stale saved path resolves by name at load time (exact → unique case-insensitive path → unique basename, with a one-line console note when it remaps). A LoRA that is genuinely missing stops the run before anything is sampled, and the error names the file — a picture that rendered without its LoRA is worse than no picture, above all for a script or an agent that would happily judge it. The error also says where the switch is.

Gear menu → Stop on missing LoRA (on by default) turns that off for this node: a missing row then warns once in the console and is skipped while the rest of the stack applies, which suits a person at the canvas who wants to see the rest of the picture. In API graphs the same switch is the on_missing input ("error", the default, or "skip"); graphs saved before the input existed get the default.

Preview thumbnails

Hovering a row's name — or any entry in the picker — floats a small preview beside the cursor when a sidecar image sits next to the LoRA file (same basename: .preview.png / .preview.jpg / .preview.jpeg / .preview.webp, or the bare .png / .jpg / .jpeg / .webp). No sidecar, no thumbnail — nothing appears and nothing shifts. The gear menu's Preview thumbnails switch turns the behavior off.

Trigger words

The info card gathers words from three places: the LoRA file's own metadata, Civitai (one click to fetch, saved beside the LoRA as the standard <model>.civitai.info sidecar), and words you add yourself (remembered per LoRA across workflows). Click a word to toggle it into the row; enabled rows' selected words are joined into the triggers output, deduplicated, in row order.

Outputs

• model: The model with every enabled LoRA applied in row order.
• clip: The CLIP with every enabled LoRA applied (unchanged when no CLIP is connected).
• triggers: Comma-joined selected trigger words from enabled rows.

Rows with a strength of 0 (both model and CLIP) are skipped at load time but still contribute their trigger words, so you can park a LoRA at zero while comparing.
