LTX-2.3-Workflows

like 393

Love your workflows, but don't like having to browse to where my safetensors files are compared to yours, like "LTX23_audio_vae_bf16_KJ.safetensors" is really "LTX23_audio_vae_bf16.safetensors" to everyone else in the world, so rather than bother you with a trivial request to update your workflow, I just created a powershell script for to fix all of them and customize them to the models I want to use.

It's written for Windows users and replaces the paths to where yours are on your machine. It saves the old version to your recycle bin so you can always recover it if you don't like the change it made.

1. Update the rootpath to where your *.json files are
2. the $replacements has the search term on left and replacement on the right so you can add more
3. save this is fixPaths.ps1 and run it or paste into a powershell window and run.
