Hi everyone!
So I finally achieved a long-time goal, a truly new slider!
You're probably familiar with how body sliders work in The Sims 4. Creators typically modify existing EA body parts and utilize unused drag directions to build custom sliders, like the old BTTB 7 Core Sliders – using Thigh and Lower Leg to adjust the penis. However, I’ve now successfully created a new body region specifically for the penis area, making it even easier to use and allowing compatibility with Body Sliders that utilize the Thigh and Lower Leg.
Core Slider V2 should now be compatible with most custom sliders you have installed, unless they're using a custom HotpotAtlas – which I haven’t seen anyone do yet.
It took me quite some time to finally figure this out, and it feels like I’ve unlocked new potential for future custom body sliders. I plan to share what I learned in a blog post and hopefully it will be helpful to the Sims modding community.
Currently, there's a slight size difference between the testicle meshes in Soft and Erect mesh, and adjustments can be slightly different. I will update this as soon as possible.
After Public Access, this slider will merge into and replace the BTTB 7 main file (C1).
I hope you enjoy it!

Merge "BTTB 7 Core Slider V2 Advance Penis+Testicles by BANK42n.package" and "BTTB 7 Core Slider V2 Advance Penis+Testicles HotSpotControlAtlas Override by BANK42n.package" into one file to improve organization and potentially fix Core Slider V2 not working for some players.
