LTX-2 - Model loading change (from late februar 2026)

See more here: https://huggingface.co/Kijai/LTXV2_comfy

Update: ComfyUI made a temporary "fix" so that the old workflows still work for now. In process of updating my workflows to reflect coming changes

The workflows are based on the extracted models from https://huggingface.co/Kijai/LTXV2_comfy The extracted models might run easier on your computer (as separate files), as well as GGUF support etc. (but you can easily swap out the model loader for the ComfyUI default model loader if you want to load the checkpoint with "all in one" vae built-in etc)
