There are two possibilities: 1. You select the model and see if it is locked in the channel. If it is locked. These parameters of rotational displacement will be grayed out. . Just right-click to unlock it. .
2. That is, they are in the layer. . Then it was locked in the floor. . On the one hand, the layer mode is changed to R. Burn it. It's good. . . .
Maybe there are other situations. I don't know yet. .
