My process to lock the right hand to the hand guard/barrel of the weapon is: Select the R_hand_bone_auto null, select Blend, Simple, RX RY RZ, select Target Object which is a Null (L_Weapon_Attach) placed at the point of contact, Select Enter. I also do this for the R_arm_bone_goal_auto, instead I use the TX TY TZ values. Then I setup an additional IK Space Switch for the L_Weapon_Attach.
This works perfectly, and now I try the same process just reversed with the Left side. This time I get a CHOP error that I just can't figure out. I have tried starting with the Left side instead of the Right and still the same error.
I did try building the Constraint network manually and still the same errors. I have also tried to recreate the three nulls for the L_hand, and no errors have appeared. When I try to constrain the L_hand_bone to the L_hand_bone_ctrl the hand loses all function. Does anyone have an idea of what this error could mean? Thanks!
