In case you're wondering, this is the mod Weirdo is talking about, if you wanna try it out before U47:

Yeah skin changing wouldn't work unless they were already coded into the mod, which isn't going to be done.

 Couldn't it be done to change into the Doctor skins from in the skin pack?

 It could, but since they are implementing an already existing code it would require some time, and u47 should come out soon according to the team's twitter

 Thanks for the clarification on that, Sub. :)

so um with the new regen do u change ur face

and stuff?

 If you read up it says "Yeah skin changing wouldn't work unless they were already coded into the mod, which isn't going to be done." so that means no, you can't change skin which includes face

 But they could possibly have the skin change to their skin pack skins of the Doctor's regenerations though.

I think this idea is amazing! But I have some new ways it could be achieved.

The server (DMU Public)as you know is keepinventory, what they could do is add this feature but make it so when you use up all your 12 regenerations or die before you regenerate you die normally and drop your stuff. But when you die and drop your stuff you are just born with a new regeneration cycle. And, you can regenerate at any time by pressing r but it takes 3 seconds to start and during that 3 second window you can still die but after that 3 seconds you can’t be hurt. 

Regarding the skin change you could just have it so you choose not to change from a pop up menu or you get a random skin from a bank of loads of skins.

let me know what you think
