[WIP] Breast Physics + Brigitte Test Animation
🕑 Added 2025-03-01 23:25:59 +0000 UTCHey all, here's a quick WIP update on some of the things I've been working on!
I took another deep dive into expansion breast physics, and lemme tell you it's a bit of a pain compared to normal breast physics. The main issue that I'm running into is that in order to get properly deforming physics, I need to use a proxy mesh to simulate on first, and then apply the same simulation to the actual body mesh. On a static model, this is pretty straightforward and you can sculpt the proxy mesh to fit really nicely with the body geometry. However, when you start expanding, the proxy mesh and body mesh start to separate, and it's tough to tune them such that the simulation looks like its affecting the proper geometry.
Long story short, the final size isn't an issue, but growing to match that final size can be a bit tedious, especially with a character and/or clothing affecting the growth. I'm still trying out different techniques, and I think I'm close to the 'good enough' mark for animations, and I'm currently putting together a short Brigitte BE animation to test out how the physics act and figure out what I can and can't do with the current setup.
The animation itself is blocked out and I've tuned the body animations, so the next steps will be adding in the breast physics and getting the colliders to act accordingly. In addition to this I've been working on porting over other models to use the updated rig, and I'm looking forward to making more animations using the new rig and proper physics. Thanks for the support, and I'll see you guys soon!

It’s been more than 6 months since your last post, is everything alright?

looks good! i've dealt with these problems as well, they are tricky indeed. If you need a hand with audio i'll happily do it as well!

Oh yeah breast expansion or any physics that have to get “Bigger” usually comes with a Pandora’s box of issue. We truly appreciate your dedication and wish you luck on furthering your craft!
