🦴 Bone Mapping (⛓ Constraint VS 🔗Driver)

the bone mapping is to get local transform form source armature to target armature and we can choose what axis is mapping to and the type of transform (location, rotation, and scale)

we can do that using constraint and driver, but I want to talk about pros and cons using constraint and driver and what I finally choose

⛓ Constraint

✔ PROS

• easy to setup and remove
• mapping axis
• offset transform when constraint is enable
• can using 2 rotation mode (quaternion and euler)

❌ CONS

• jagged animation
• has limit transform (that's make jagged animation because blender need to clamp transform value)
• not easy to bake using python code (buggy)

🔗Driver

✔ PROS

• smooth animation
• easy to bake (using python keyframe_insert)
• more control axis mapping
• can using 2 rotation mode (quaternion and euler) using python code

❌ CONS

• hard to setup and edit
• mapping axis individually
• can not use offset when drivers is enable

Conclusion

the conclusion is i'm using constraint and driver, driver for tweak bone, and constraint for control bone (pole and IK control)
