I imagine this has been asked and answered somewhere before... but I've been looking for a while and can't find it.
Can someone provide me an explanation of the process of porting BFA models (player, NPC, creatures, etc.) to Cataclysm 4.3.4? What tools would I need to use? What would the process be? Etc. etc. I can't find exactly what I'm looking for anywhere. And I'm wondering about both just the M2 file, as well as the M2 files WITH the .skel file. I've tried going from BFA or Legion down to WOTLK, and back up to Cataclysm, but with no luck. The client crashes every time I add the "converted" model.
