Homebrew HDT version of DarkConsole's Mana Tanks - Need Help

[TeamJimmyJohns]

Hi! Quick backstory - I've been a lurker on a throw-away account with a 10-minute-mail for a bit now, but I decided to both make a real account and get into editing some mods. One of my favorite mods on this website is DarkConsole's Mana Tanks mod, and as a bit of a self-tutorial to get into modding, I've been bashing away at making his mod compatible with HDT physics. After learning about .PEX and .PSC formats, Papyrus Compiler, Outfit Studio and some of how bones work from XPMSE, I've *almost* gotten the mod to work properly. However, I run into the issue below, that I'm not quite sure how to solve:

 

 

 

As you can see, the nipples begin to curve up as if they're being pulled by something, and the physics totally break and can freeze the game if it goes for too long. Currently, it only seems like it happens when the breasts change size quickly or frequently - most notably when dual-casting spells or setting Mana Tanks' refresh rate to a too-small interval during recovery. Casting cheap basic spells one at a time typically doesn't break the physics like shown above, and it's easily fixable by resetting the HDT physics by toggling CBPC/SMP modes (From 3BBB on Nexus). For my personal intents and purposes (using the "link size to stat maximum" and having them grow over time as I put levels in Mana/HP/Stamina I.E. not changing size in real-time), this setup currently works fine, but I'd love to be able to nail this down if I ever get permission from DarkConsole to release this. Does anyone know why this happens, or what I might be able to do about it?

 

Additionally, for anyone more versed in HDT XML's than myself, is there any way that the weight/gravity of the breasts could be altered in real-time, so that the breasts could be "heavier" when large and more bouncy/light when small? That would be a neat feature, but I'm not sure if there's currently a good way to do that on the fly.

 

Thanks!
