ComfyUI: LTX-2 Full Model workflow and LoRA integration

Demo summary

The demonstrator shows the full model checkpoint workflow, including connecting a distilled LoRA for speed and adjusting sampler steps and CFG values for better prompt adherence.

Step-by-step

  1. Load the full model checkpoint and the specific VAE
  2. Connect the distilled LoRA to the second upscaling stage
  3. Set the LoRA strength to 0.6
  4. Select the LTXVuler instead of sigma values
  5. Increase the first stage steps to 20
  6. Set the CFG value to 4
  7. Select the res 2S sampler

Options

  • Adjust steps between 15 and 40
  • Set CFG value between 3 and 6
  • Experiment with different samplers for varied results

Watch out for

  • High CFG values can introduce unwanted textures and contrast to the output

Tips

  • Use a distilled LoRA to speed up generation time
  • Set LoRA strength to 0.6 for the best balance of speed and quality
  • Use a CFG of 4 for good prompt adherence and refined details
  • Higher CFG values result in better prompt adherence

Highlights

0.6, which we found is a sweet spot in terms of speed and quality
