This has been helpful, I did all the steps up to step number 7 but I don't know how to do step 8. Can you post how to do that part please and thank you in advance on any reply
Hi mate, ye my explanation was a bit short. OK so you've done step 7 right. Bigger explanaton on step 8:
Go into node constraints. click on your female character or whomever you want to replace with. It will see their IKs and FKs.
Whenever you go through the various nodes and you see the node attached to your characters body, you have to set it to your character (Like the image above).
In this case, click on your characters red or blue circle which matches it directly like above. In this case it is the knew and I know that this constraint is related to my new character. Now we have to set that constraint to my new character, which depends.
If the body part is on the right (top right of the nodes constraints screen like above) such as in this examlple 'f_t_knee_L (work)', it is the child. Simply click set as child, then click 'update selected'.
However, if that body part is on the left, then it is the parent. What I would usually do is "set as parent", then click on "use current" for whichever positions are highlighted, then click on 'update selected'.
I hope that gives you more insight into it.
