(PATCHED) Roblox Studio BUG! R6 Animation Editor is BROKEN! (With Temporary Fix) | Roblox Studio Bug
There is currently a bug going on that is not patched that occured after a roblox studio update. If you use the default roblox studio animation editor on a R6 Rig, you wont be able to select the torso or the head. You also won't be able to see the keyframes. The only temporary fix is to set the PrimaryPart of the rig to the HumanoidRootPart.
