The problem that I live in may not be a bug. but I could not find any solution.I searched on the internet, but I could not find anything useful.
I recorded a small, quiet video Video problems start at 2 minutes
The problem is actually, I want two different Armatures to be one. Size changed when adding "hidden blade" model to Armature product group. I don't know what this problem is.
The second problem is related to moving the bones. After moving the bones, they press Alt+G (or S, R) to come back to the very beginning. I want to fix the bones of the model to the new position after moving.
for example, I move the bones of the model. I'm bringing it to a nice position. When I export, the positions of the modell bones are zeroing.
I mean, I change the position of your bone, but when I hit Alt+G you press not go back to your old position.
