Helper Bone Setup

After selection of the armature, designated helper bones will be given constraints that allow for them to deform the way they could do in engine if defined through a .vrd file. It is not a 1:1 recreation, it only includes rotational values and it is exclusive to Blender, meaning that it will not make them work in engine without said .vrd file defined.

The affected helper bones are as follows:

Shoulder

• Driver Bone: Upperarm

Ulna/Wrist

• Driver Bone: Hand

Ulna

• Max Rotation: 50°

Wrist

• Max Rotation: 90°

Elbow

• Driver Bone: Forearm
• Max Rotation: 45°

Knee

• Driver Bone: Calf
• Max Rotation: 45°

Notes

There are more helper bones in standard armatures (Such as the bicep) but not all of them are given a purpose (That i'm aware of), so they're left untouched.

These rotational values can be modified to your desire, but the values given should be enough in the majority of cases.
