C4D noob here. I created some simple models and was in the process of animating them when the key frames stopped working. I can drop simple objects into the scene and animate them but the models originally in the scenes will not animate.
I tried merging but models still won't animate. I tried copy and pasting and that did not work. I exported the models into an .obj and brought that back in and that did the trick.
So I am guessing I did something simple and turned something on/off that froze all my animations. At least that is what I am hoping.
