Why did you not use any FK Switches for the legs.

The reason why is because this rig is a little bit… cursed? I guess?
Adding FK Switches to the legs is really difficult and not really important most of the time, though I could try again with it.

what are the grab points used for. Or how would you use them, I cant really see a use for them as they kinda work like the ik bones.

Grab points are in the name, they grab onto stuff that are solid, this is good for like, say holding onto a handle bar in the animation, or you could add a Child Of to each Grab Point that’s set to another rig’s arm to make a cool arm grabbing effect when being picked up (Seen in @Tarazicon’s animation above)

I want to add custom hilts for my weapons in game so that I can animate the “Handle”. If you dont mind would you mind sharing how I should add new bones?

I’ve ALWAYS had issues with adding new bones to the import and export blender plugin, I think it’s something to do with the _RigMeta and it not having data (like, if I wanted to add a bone, I think the _RigMeta would need changes somehow.)

I also noticed that the position of the bones isnt fixed its float values. So the right hand bones are like 1.5012134. instead of 1.5. is this intentional?

I’m pretty sure this is just blender being blender, but no, it’s not intentional but it shouldn’t effect the animation in any way.
