Tips
select model -> Settings -> Troubleshooting -> Apply Body Rotation To Center=ON
If that doesn't work, you can also try the following.
DanceXR has a problem with some CG models twisting their waists.
If you convert from VRM to PMX using VRmToPmxExporterSetup or Vroid2Pmx, DanceXR has a 100% chance of causing the CG model's waist to twist.
MMD probably doesn't have this problem.
The problem is noticeable when the motion is one rotation.
For example, the problem is noticeable with PiNK CAT's motion.

You need to modify the model using PmxEditor.
Method 1: Delete the 腰(waist) bone with PmxEditor.
Method 2: There is a way to correct it using the PmxEditor plug-in [ツール]MMD変換したVRM(Vroid)を使いやすく最適化([Tool] Optimize MMD converted VRM (Vroid)」 for ease of use).
This plugin is only available in Japanese.
If you delete the 腰(waist) bone with PmxEditor, the problem can be corrected with a probability of over 90%.
Although it is rare, depending on the model, it may be necessary to rewrite the parent number of the bone after deleting the 腰(waist) bone.
If deleting the 腰(waist) bone does not work, try the PmxEditor plug-in without deleting the 腰(waist) bone.
You can try out the plugin from the beginning.
However, this plugin is the Japanese version.
For the EYO model, deleting the 腰(waist) bone caused the mesh to collapse and failed, but I was able to fix it with the plugin.
As a result of what I tried, the 標準ボーンチェッカー(Standard Bone Checker , CheckBasicBone.dll) and 準標準ボーン追加プラグイン(SemiStandard Bones Addition Plugin , SemiStandardBonesPMX.dll) plug-ins of PmxEditor could not fix this problem.
PmxEditor is available in Japanese, but there is also an unofficial English version.
PmxEditor 0.2.5.4 English ver. , Unofficial
PmxEditor 0.2.7.3 Japanese ver.
