When i go to equip a different look i get the sound but no change is made to my character anyone else having this problem? ive tried turning off addons and checking if anything is not transmogable
In which version of the game are you having this issue?
Have you tried transmogging piece by piece instead of all at once?
Are you trying to transmog over a piece of gear that is not the same type (i.e., trying to mog leather over cloth for example)?
TWW, im in all plate i have tried Tmog piece by piece
It could be that there is a piece that is glitching with an old appearance. Placing a piece of gear into Void Storage will strip it of all appearances it has. If an item is not unique, it can be placed into Void Storage. That might be an option for you to try.
In addition, have you tried a different transmog NPC OR a different location? I experienced some issues with the Transmog NPC on my Yak last night on a new character to TWW. I had to leave Dornogal to even get the NPC to show up and work correctly.
