As shown in the picture, using blend joints in the assembly, I found a small problem, the global scaling of “blend_leg_L0_0_jnt” and “blend_leg_R0_0_jnt” is incorrect.
The reason I analyzed is that the scale attribute of the joint “spine_C0_0_jnt” is acceptable for global scaling, and the two joints “blend_leg_L0_0_jnt” and “blend_leg_R0_0_jnt” are not below the top level of the “spine_C0_0_jnt” joint level, so the global cannot be completed. Zoom.
My solution is to break the “.scale” attribute of the two joints “blend_leg_L0_0_jnt” and “blend_leg_R0_0_jnt” in the post custom step, and use the “leg_L0_0_jnt” and “leg_R0_0_jnt” respectively to the scaling constraints “blend_leg_L0_0_jnt” and “blend_leg_R0_0_jnt”. , and finally completed the global zoom.
Looking forward to your better approach
