ComfyUI'de Load LoRA düğümü

Load LoRA (LoraLoader) applies a LoRA file to the MODEL and CLIP with separate strengths, so a style, character or concept can be added to any checkpoint without merging.

Load LoRA ne yapar

A LoRA is a small patch trained on top of a base model. Load LoRA takes the MODEL and CLIP coming from a checkpoint loader, applies the patch, and outputs new MODEL and CLIP objects. Everything downstream (prompts, sampler) then uses the patched versions. Several Load LoRA nodes can be chained to stack LoRAs.

strength_model scales how much the LoRA changes the diffusion network, strength_clip how much it changes the text encoder. Most LoRAs are made for 0.6 to 1.0 on both. Negative strengths push the model away from the concept. LoraLoaderModelOnly is the same node without the CLIP side, which is all most Flux and video LoRAs need.

Load LoRA nasıl kullanılır

Put the LoRA file in ComfyUI/models/loras.
Insert Load LoRA between the checkpoint loader and the sampler: model and clip in, MODEL and CLIP out.
Connect the CLIP output to the CLIP Text Encode nodes, not the original checkpoint CLIP.
Pick lora_name and set both strengths, starting at 0.8.
Add the trigger words from the LoRA page to the positive prompt.

Ayarlar ve ipuçları

The LoRA must match the base family: an SDXL LoRA does nothing useful on SD 1.5 and a Flux LoRA fails on SDXL.
When stacking LoRAs, lower each strength so the total stays near 1.0 to 1.5; stacks at full strength burn the image.
A LoRA that only changes the model (no text encoder layers) prints "lora key not loaded" for CLIP keys; that is harmless.
For a quick A/B, set strength_model to 0 instead of unplugging the node; the graph stays wired.
Use a LoRA stacker node from a custom pack (rgthree Power Lora Loader, Efficiency LoRA Stacker) when you regularly use more than three.

Load LoRA sorun giderme

lora key not loaded: lora_unet_... (dozens of lines)

Neden olur

The LoRA was trained for a different architecture than the model it is applied to, so none of its layer names match.

Nasıl düzeltilir

Check the LoRA page for its base model (SD 1.5, SDXL, Pony, Illustrious, Flux) and pair it with a checkpoint of that family. A handful of unmatched keys is normal; hundreds mean the wrong family.

The LoRA has no visible effect

Neden olur

The CLIP Text Encode nodes are still wired to the checkpoint CLIP instead of the LoRA output, the trigger word is missing, or strength is 0.

Nasıl düzeltilir

Rewire both prompt nodes to the CLIP that leaves Load LoRA, add the trigger words, and raise strength_model to 1.0 to confirm it works before tuning down.

Images are oversaturated, deep-fried or full of artifacts

Neden olur

Combined LoRA strength is too high, often because several LoRAs run at 1.0 together or an overtrained LoRA needs less than 1.

Nasıl düzeltilir

Lower strength_model to 0.5-0.7 per LoRA and keep the stack total around 1.2 or less. Raise cfg slightly if detail disappears.

Error: Expected size for first two dimensions of batch2 tensor to be... (shape mismatch)

Neden olur

A LoRA of the wrong rank or family is being applied to CLIP, typically an SDXL LoRA with strength_clip above 0 on a Flux CLIP.

Nasıl düzeltilir

Use LoraLoaderModelOnly for Flux and video LoRAs, or set strength_clip to 0.

Load LoRA hakkında sorular

Can I load several LoRAs?

Yes. Chain Load LoRA nodes: the MODEL and CLIP outputs of one go into the next. Order rarely matters; strengths do.

Should strength_model and strength_clip be the same?

Usually. Lower strength_clip when the LoRA hijacks the prompt too strongly, lower strength_model when the style is too heavy.

Do LyCORIS / LoCon / DoRA files work here?

Most do, in the same node. Very old formats may need the LyCORIS custom node pack.

İlgili düğümler

Load Checkpoint

ComfyUI core

Load Checkpoint (CheckpointLoaderSimple) opens a .safetensors or .ckpt model file and hands out the three parts every workflow needs: the diffusion MODEL, the CLIP text encoder and the VAE.

CLIP Text Encode (Prompt)

ComfyUI core

CLIP Text Encode turns a text prompt into CONDITIONING using the model text encoder. One node holds the positive prompt, a second one the negative prompt.

KSampler

ComfyUI core

KSampler runs the denoising loop: it takes the model, prompts and a latent and produces the finished latent image, controlled by seed, steps, cfg, sampler, scheduler and denoise.

Load Diffusion Model

ComfyUI core

Load Diffusion Model (UNETLoader) loads a bare denoising network such as Flux, SD3.5, Wan or HunyuanVideo from models/diffusion_models, with a weight_dtype option for fp8 to save VRAM.
