So, I recently used the ReplayMod to record a video for my YouTube channel, but when I disguised myself using the iDisguise plugin, it did not show up in the replay. Is this due to me being the one disguised and recording? Can someone please help?
Yes, the ReplayMod can only know your view of the world and if you press F5 or look in your inventory, then you'll see that you're not actually disguised for yourself.
