Boolean Switches not working
I am not sure why, but on some of the workflows, the boolean switches do not work. For example, I am working on the FFLF with transition lora workflow and there is the custom audio and the prompt enhancer boolean switches. When I switch them to false, nothing happens and when I run the workflow, it tries to process the nodes that should be switched off and the workflow doesn't go because I am missing the audio file that it wants. Most of the workflows with boolean switches work just fine, but a few of the workflows don't.
will check if anything has changed with comfy. Those switches were beta, but should still work same way.
Will take a look ;-)
I couldn't either and then I discovered the Set-Get nodes behind the switch became disconnected somewhere along the line. I made tons of updates to the WF on my own and probably messed them up. I went back and looked at the original and copied the connection back to my newer WF and it's working again. It also reminded me why LTX NEEDS the I2V. It REALLY stinks at T2V. Starting from an image keeps my swear jar from overflowing. Thanks for such a great WF! Your foundation has really taught me a lot.
