    lora_switch_3BOOLEANfalseEnable LoRA 3
    lora_name_3COMBONoneLoRA 3 file
    lora_weight_3FLOAT1.00-10–10LoRA 3 model weight
    sampling_methodCOMBONoneSampling method: SD3 (shift=3.0), AuraFlow (shift=1.73), Flux (max_shift=1.15), Stable Cascade (shift=2.0), LCM (distilled), ContinuousEDM/V (continuous sampling), LTXV (video)
    sampling_subtypeCOMBOepsSubtype for ContinuousEDM sampling
    shiftFLOAT3.000–100Universal shift parameter (SD3: 3.0, AuraFlow: 1.73, Flux max_shift: 1.15, Stable Cascade: 2.0)
    base_shiftFLOAT0.500–100Base shift for Flux/LTXV sampling (default: 0.5)
    sampling_widthINT102416–32768Width for Flux sampling shift calculation

    sigma_minFLOAT0.0020–1000Minimum sigma for ContinuousEDM/V sampling (EDM: 0.002, V: 0.03)
    blocks_to_swapINT50–100Number of transformer blocks to offload from GPU to CPU. Higher = more VRAM saved but slower inference. Suggested ~value (max total blocks): flux/chroma ~10 (max 57), sd3 ~8 (max 24-38), wan ~10 (max 30-40), hunyuan-video ~10 (max 60), ltxv ~6 (max 28), cosmos ~8 (max 28-36), zimage ~10 (max 30), qwenimage ~20 (max 60), mochi ~10 (max 48), hidream ~10 (max 48). Set to 0 to disable.
    offload_embeddingsBOOLEANfalseAlso offload embedding and projection layers for extra VRAM savings.
    ltx_text_encoderCOMBONoneOptional LTX2/LTXV gemma text encoder (from the text_encoders/clip folder, GGUF or safetensors). When set, it is combined with the loaded Standard Checkpoint / UNet file's baked text-projection to build a correct LTXAV CLIP, overriding the (empty) baked CLIP. Leave as None for normal baked-CLIP behavior.
