I cant open survival morph menu. I can change morphs in survival with ,,next morph" and ,,previous morph" when in survival and when creative i can open creative morph menu but still no survival menu. Is there a way to fix it please? Also i have a question is this mod server compatibile? And if no are you planning to do it? And if it is who has acces to morph ability? Can i change it so for example only opped players can do it or something?

For the survival morph menu: What version of Metamorph and Minecraft? Did you check the Controls menu to make sure there is no keybind conflict (key appears red?)

What asanetargoss said, it's probably key bind conflict. 👆

Yes, this mod is multiplayer compatible, and, no, I'm not planning to add feature to allow specific players to morph.

No its not key bind conflict. It was when i first installed the mod but then i changed for ctrl+n and it worked in 1.10.2 and then i upgraded everything to 1.12.2 and it doesnt work doesnt matter which key is selected
