    I cant find this crap anywhere.

    I did install your monkey custom stuff.
    How do we fix this?

    Not OP but, it's supposed to be in ComfyUI-KJNodes, but no matter how many times I updated that node package I could not get it to work so I just took the code changes from these two file updates for "init.py" and "nodes/ltxv_nodes.py" and manually updated the files in my comfy install and it works.

    @TheAIDoctor Thank you so much. I changed those two files as well, and now the node loads up. I was racking my head over this stuff.

    TheAIDoctorJan 20, 2026

    @HellBoundSinner Glad it helped! Just keep in mind, that might prevent updates of the KJ nodes in the future because the git pull may detect the change in the file and you would either need to stash the changes or just delete and redownload the KJ nodes folder.

    @TheAIDoctor Awesome, glad I wasn't the only one.
    Usually when I see a good workflow but no one posts their own generations.

    The Original Poster should suspect that something is going on. ill give this a try. :P

    TheAIDoctorJan 20, 2026

    @Megasherru I actually haven't even tried this workflow yet, I just knew how to solve this one from the same issue on another workflow. I imagine there's quite a few LTX-2 workflows out there currently with this problem. I'm not sure if it's an issue with KJ-nodes, Comfy-ui Manager or Comfy itself
