Tail Addon [v1.3]

If you're talking about the default 2D tail, there's a folder that contains everything you'll need. But if you've already read the instructions, then all you would need to do is to re-texture your skin to match with the example skin.

If you're talking about the 3D tail, there is also a instructions file you would need to read. To put simply, there's a extras folder in the Tail Addon folder; You would need to copy and paste the 'models' folder in the extras folder to the Tail Addon. If your phone/PC tells you 'something with that name exists already', tell it to continue. Then, you would then need to take the .bbmodel to a program called BlockBench, importing both your skin and the sample_skin2 file in the guides folder in the Tail Addon folder. Copy the sample_skin2's pixels as closely as you can. Once you finish, just save your skin, launch Minecraft and equip your skin.

And, you're done. Hopefully this helps! :D

Apology for responding late, I meant to get to this sooner.

Which tail version are you using? Both of them use your skin as their textures, just been placed where else. Kind of like Action & Stuff's blinking animation.

If you look for a folder called "guide", there'll be a texture called "sample_skin.png"; You would use that skin in any image editor such as Medibang Paint Pro, Blockbench, Krita, etc.

Now, relating to the bug, can you tell me what exactly experiencing?

Cause, I think I know what the problem is but wanting to double check on exactly what you mean.
