ComfyUI-PowerLTXLoraLoaderExtra is a custom node for ComfyUI that gives users precise control over multiple LoRAs in LTX2 video generation workflows. The tool provides layer-specific strength adjustments for different aspects of video and audio generation.

Developer Phazei created this node to address limitations in the standard LoRA loader, which lacks fine-grained controls for LTX2's multi-modal architecture. Users working with both video and audio components in their AI projects can now adjust each layer independently.

Layer-specific LoRA control

  • Separate strength sliders for Video, Audio, Video-to-Audio, Audio-to-Video, and Other layers.
  • Load multiple LoRAs simultaneously with individual enable/disable toggles.
  • Drag-and-drop reordering and click-to-edit value adjustments.
  • JSON output port for integration with other nodes in ComfyUI workflows.
  • Raw config editor for copying and pasting entire LoRA setups as JSON.

Video creators working with LTX2's multi-modal architecture will find this tool useful for fine-tuning how LoRAs affect different aspects of their output. The ability to adjust video and audio layers independently means users can apply style changes to visuals without affecting sound, or modify audio characteristics without altering video content.

Built for Multi-Modal Workflows

The node is based on the Power Lora Loader concept but extends it with features specific to LTX2's architecture. Phazei explains the motivation:

'If you're working with LTX2 video generation and using LoRAs, the standard loader doesn't give you enough control.'

The tool also supports sidecar .json metadata files that load automatically when placed alongside LoRA weight files.

Users can install the node through ComfyUI's node manager or by cloning the repository into the custom_nodes directory. The interface includes visual feedback for drag-to-reorder operations and preserves configurations even when LoRAs are toggled off.
