I need to quickly and easily do some bug testing with THS while in vampire and werewolf forms. Anyone here know if its possible to fully transform into a vampire or werewolf quickly and easily such as a simple console command?

You can use setrace setplayerrace

Get a list of races with help race 0

Edit: sorry, vague command--player.setrace or setplayerrace would both work.

Thanks for the help Dreamking but the solution to this was actually quite simple. All you need to do is addspell to get the base functionality in place then change the globalvariables such as playeriswerewolf and you can become a vampire or werewolf really quickly and easily.
