I noticed in the DMX monitor there was no output of DMX data from the fixture.

I wasn't aware of any Universe/Channel conflicts but eventually realized there were, especially when testing with Real and virtual fixtures in a render application like Unreal.

Is there a way to identify conflicts or export these into another data format so you can identify these?

You want to detect if two fixtures are writing to the same DMX channels ? So this is not related to MadMapper 5.7.0 specifically right ?
There is no such option at the moment.
