How to configure hands locations
Open your .iaentitymodel model file with Blockbench.
Select the base bone of the entity hands.
Create a new group which will be a child of the hand bone.
Right click on the bone and select "Bone Config", in this case left_hand_slot
Check the "Left hand pivot" option and press "Confirm".
The hand pivot bone has a new icon now, as you can see.
Follow the same steps to specify the right hand, then you have to export the model as usual.
