Does anyone know a console command which will allow me to alter my character's weight?
When I was creating my character, he looked pretty good at that time, but latter, when I ended up undressed because of lycanthropy (and not because I'm perverted, no matter what you heard about me), I've noticed that I was actually one skinny son of a [censored] (hehe, it's funny because a [censored] is a female dog and wolves are related to dogs and I'm a werewolf, hur-hur, herp, derp, durrr).
So, can anyone http://www.youtube.com/watch?v=3t8MeE8Ik4Y me with this?

Put on some clothes again? As it seems that it wasn't noticeable when you were wearing clothes.

press ? (consol button) in game and then adjust stuff, don't adjust what race you are though

But now that he has noticed it, it will probably be the most noticeable thing about his character, and will bother him until it's fixed.

"showracemenu - Bring up character customization menu.
NOTE: Your health Magicka, Stamina, and Health levels will be spread evenly on using this depending on your character's level. It will remove any point distributions that were custom.
NOTE2: Make sure you are in the third person view before editing your character, otherwise you will be invisible, and unable to see the changes made on your character
NOTE3: can be Used as Vampire to fix Odd Skin/Facecolor Matchings and will not Spread your Stamina/Magica/Health Levels while you use it as Vampire, if you changed something while be Vampire and Cure yourself with lycanthropy the light Skin will stay...but also here you can use Showracemenu and alter it back to normal again without merging Stam/Magic/Health (can only confirm this as Argonian)
NOTE4: will NOT modify your attributes/skills/points/etc. unless you change the race, six, or select a preset from the list. Modifying purely cosmetic things like skin color/warpaint/hair/face shape/etc. will leave your points unchanged. TIP: if the character moves it's hands in front like they were tied, it's a clear indication that the skills will be messed up; if the hands remain parallel to the body it's fine.
NOTE5: A way to fix the modified attributes error is to simply re-equip your gear. It may not be the best fix but it is better than nothing.
NOTE6: will remove racial resistances when used until you re-load from the main menu.
NOTE7: If you are a vampire, using showracemenu to change your race will cause you to be unable to feed; however, you will still progress through the stages of vampirism."

To fix the Health/Stam/Magicka distribution, use:
"player.setav - This also works attributes such as health, stamina, magicka, meleedamage, and carryweight. Note that certain attributes (such as carryweight) may revert to their original values upon loading a game."

open console and input: showracemenu

Thanks for the help, people!
I'll mess around with that until I get it right.
