extrapolation in graph editor in blender 2.8 I wanted to create a spiral rotating at constant speed. I created my spiral, made two keyframes with linear interpolation and then wanted to add linear extrapolation, but for some reason, when I right click on the channel in graph editor, all the options under extrapolation are greyed out. I am not sure, whether this is just blender 2.8 thing, or I just made some stupid mistake or overlooked something... What could be the cause of this? Or is there some workaround or something? Thanks in advance.
May the graphs are made readonly by accident.
Go into the graph-editor, position your mouse on the left and expand the graphs label. Then hit TAB and watch, whether the tiny lock symbol shows an opened lock.
