I have really like this mod but it really sucks when you hold it, its a cube, and when its in your inventory its a cube, would it be possible to make the ugly cubes go away?

That shouldn't be happening
Could you provide a log?

hey, yea i can, btw this is the 1.20.1 version of the mavm mod

this error occurs when holding the axolotls in buckets, btw not only the lucia axolotl

But you're reporting the issue on the MAVAPI repository... Anyways the bucket textures are handled in the API so it's whatever
Please send the log as i need it to debug what's going on since you didn't even specify what modloader you're using.

sorry, I thought that this issue was related to MAVM as it says axolotl name (MAVM) completely my mistake, apologies

Apparently you have a mod that loads fabric mods on forge. That breaks the load of the custom axolotl textures and there is no other solution than remove that mod if you want to fix that, i'm sorry.

ah alright I figured that would be the cause, thanks for helping me, sorry again for uploading the issue here
