Transgender Trait  

This is a very simple trait which disallows/allows access to the breast slider for transgender Sims, while still retaining the female/male assigned sex. It is intended to more genuinely represent chest reconstruction and is available for Teens through Elder.

How the Trait Works

• Create a Sim and select the Transgender trait, found in the Lifestyle category. It is not recommended you physically customize the Sim at this time, as restricted access/access to the sliders requires the trait to be recognized in-game first. If you already have an existing Sim and are adding the trait to them, they will still need to follow the next steps
• Move in the Sim(s) and/or enter the game
• Direct the Sim to sleep
• When the Sim awakens, open the cheat window (CTRL + SHIFT + C), enable the cheats console (testingcheats true) enter the cheat which allows full editing to the Sims in CAS (cas.fulleditmode)
• Enter Create-A-Sim and customize the Sim

Sims who were assigned female now no longer have access to the breast slider, regardless of the masculine or feminine frame. Sims who were assigned male now do have access to the breast slider, regardless of the masculine or feminine frame.

Known Issues
Sims who were assigned female will not be able to go topless; the basic bra/underwear still appears. They will appear topless in the shower or if the "Change into Nude" outfit change is chosen, although it does not perfectly mimic an assigned male Sim's chest. Similarly, in CAS, when selecting tattoos, the basic bra/underwear still shows
Sims who were assigned male will not be able to go topless. However, in CAS, when selecting tattoos, there is no bra/underwear although it does not perfectly mimic an assigned female Sim's chest
Because this is a CAS trait, it can appear on randomly generated townies, which can result in inconsistent gender expression as far as clothes, hair, facial hair, etc. I didn’t feel it would be appropriate to make this a reward trait (either purchasable or via aspiration) and I do not have the scripting knowledge to code something that would restrict the trait from being available to said randomly generated characters. I appreciate your understanding and can only hope someone with more coding knowledge than myself can create something that does what this trait does - but better - some day soon
