Thank you for Licon MSR multi reference WF. Anyone can combine it with LTX Director (WhatDreamsCost) nodes in WF?

Should be possible yes. They both can work on their own, but a combo might work even better, for consistency.
will do some workflows with the latest MSR lora asap. It's an interesting lora where you dont have to put everything into first frame
