A new mod has appeared that provides real-time physics of a real body. It gives the rest of the bodies movement by moving other people.
Real Time Body Physics is an experimental Sims 4 mod that attempts to add real-time body physics to simulations. It currently only targets the chest and buttocks, but other parts may be added in the future.
At this stage, the mod is very problematic. Sometimes the wrong vertices are selected and you see fingers or faces jumping.
The mod works through a fake DirectX 9 DLL, which behaves just like the real one, but adds a little extra code to the render loop.
Please read the attached «README.html» file before using this mod. It explains how to install, configure and manage the mod in the game.
On a 32-bit sims will not work.
