Noob question about physics

[valencia]

If you go to outfit studio and look at the bones tab for any HDT-PE based outfit, you can see that there are Calf and Thigh bones enabled just like how bones related to Breast or Butt. However in-game, you can only see breast and butt jiggles and not calves and thighs.

 

I personally use SMP but I was wondering why would there be thigh and calf bones in HDT-PE that are enabled but have 0 effects in-game? and is there a way to sort of enable them and make them jiggle similar to how the breast and butts jiggle in HDT-PE outfits? I do have the havok modifier thing but have never used it. Thanks in advance.

The effect for jiggling/moving is coming by a file, which is telling the part to become moving. If you now have inside of this file no infor for those parts of the body, this parts simply do not move. It´s possible to let run HDT-PE aside of SMP, but it´s important that your tasks of physics-files are not mixing same regions to not waste recourses or get bad effects.

If clothing shall be moving, the naked body has to show the effect as well. Upper-leg moving and butt- moving is supported by SMP but I am not sure if upper legs are also triggered by HDT-PE without customizing those. The butt-yes. At the moment I am working at a SMP-body, which uses SMP for everything and soon I will try to drive that body also with HDT-PE for a comparison. The BONES are holding the skin/mesh and have info about the angulary bending of the skeleton. Important restrictions of angulary maximum-bending so to offer a "realistic ragdoll" effect-simulation. The mesh has to follow those bending-angles and that ´s achieved by the weightpainting. HDT-effects simmulate a gravitation-effect on the dedicated parts if the mesh is moving. If clothing becomes weighted, also the clothing is moving same way with the body-mesh.
