Maya not keyframing properly!
So I'm working on a Maya animation project at school, and Maya has been working fine- until now. It doesn't keyframe properly. I'll set something like rotate, scale, move, etc and set a keyframe, then go ahead to another frame and set another keyframe, but Maya is not making an even gap between the two keyframes.
IE, I'll set Rotate Z to 5 for Frame 1, then Rotate Z to -5 for Frame 16, but when looking at it, Rotate Z will go back to 0 at frame 4, then jump up to -5 at frame 16, then go back to 0 again by frame 19 or so.
Anyone know what's going on? It's kinda stopping me from progressing any further
