- Added the “LTXEulerAncestralRFScheduler” scheduler, aligned with [sample_euler_ancestral_RF](7d6103325e/comfy/k_diffusion/sampling.py (L234))
- Updated the LTXI2VLongMultiPromptPipeline.from_pretrained() method:
- Now uses LTXEulerAncestralRFScheduler by default, for better compatibility with the ComfyUI LTXV workflow.
- Changed the default value of cond_strength from 1.0 to 0.5, aligning with ComfyUI’s default.
- Optimized cross-window overlap blending: moved the latent-space guidance injection to before the UNet and after each step, aligned with[KSamplerX0Inpaint]([ComfyUI/comfy/samplers.py at master · comfyanonymous/ComfyUI](https://github.com/comfyanonymous/ComfyUI/blob/master/comfy/samplers.py#L391))
- Adjusted the default value of skip_steps_sigma_threshold to 1.
