## 此节点包中的节点

### latent

- 🅛🅣🅧 LTXV Spatio Temporal Tiled VAE Decode

### Lightricks/audio

- 🅛🅣🅧 LTXV Audio Only Empty Video Latent

  Fixed minimal placeholder video latent for audio-only (text-to-audio) generation - a single 64x64 frame. LTX-2 needs a video latent at input index 0, but with LTXV Audio Only Model it is never attended to, so the dimensions are fixed (and hidden) to avoid confusion. Join it with the audio latent via LTXVConcatAVLatent.
- 🅛🅣🅧 LTXV Audio Only Model

  Run the LTX-2 audio/video model in audio-only mode for text-to-audio. Skips the video stream and disables the audio<->video cross-attention, so the generated audio does not depend on the video latent. The sampler still needs a minimal dummy video latent (EmptyLTXVLatentVideo at 64x64 length 1, joined with LTXVConcatAVLatent); it is never attended to. Remove or bypass this node to restore normal joint audio+video generation.

### lightricks/LTXV

- 🅛🅣🅧 Gemma 3 Model Loader
- 🅛🅣🅧 Guider Parameters
- 🅛🅣🅧 LTXV Apply STG

  Defines the blocks to apply the STG to.
- 🅛🅣🅧 STG Advanced Presets

### ltxtricks

- LTX Attention Bank
- LTX Attn Block Override
- LTX Flow Edit Sampler

### ltxtricks/attn

- LTX Attention Override

### LTXV/loaders

- 🅛🅣🅧 Low VRAM Audio VAE Loader

  Loads an LTXV Audio VAE checkpoint with dependency support. Connect 'dependencies' to a previous loader's output to ensure sequential loading and reduce peak VRAM usage.
- 🅛🅣🅧 Low VRAM Checkpoint Loader

  Loads a diffusion model checkpoint with dependency support. Connect 'dependencies' to a previous loader's output to ensure sequential loading and reduce peak VRAM usage.

### math/conversion

- 🅛🅣🅧 Float To Int

### prompt

- 🅛🅣🅧 LTXV Multi Prompt Provider
- 🅛🅣🅧 Multi Prompt Provider

### sampling

- 🅛🅣🅧 LTXV Base Sampler
- 🅛🅣🅧 LTXV In Context Sampler
- 🅛🅣🅧 LTXV Looping Sampler
