Hi~ I’ve been following quite an old tutorial (and so far so good) but I suddenly got stuck during the rigging process.
We modelized a robot’s right leg and rigged it. Then instead of doing it all over again for the left leg, we duplicated everything and used scale on x axis -1 to make a symetry. Now, I have my left leg ! However, when I do that, part of my bones disappear in object mode, while they appear in pose mode but can’t be selected (they turn grey too).
As you can see bellow, the foot bones are selectable and the rig works just fine. However, when it comes to the arm and shoulder bones, I can’t do anything with it
Would anyone have an idea of why it does that, and how to fix it? I’ve been giving myself a headache over this, it’s time I ask for help x)
