When I press the villager option it doesn't show my skin. I use Minecraft Launcher.

i have the same fkng problem man how we can fix that i want to play with my own skins

Does it happen without any other mods?

Well, forgot to mention that this happens to me when I'm playing on a cracked server, like Aternos, and I can't see anyone's else skin. This may have nothing to do with the mod and occurs due to the type of the server.
