Shape key setting so that value slider doesn't work I have an object that when I make a shape key it doesn't go back to 'basis" when I tab out to object mode. The slider has no effect. I can change it between basis and the key only by selecting basis or the key.

I added a default cube and keys worked fine. I then compared for anything I could think of and nothing stands out. I've applied transformations (and not). It's not parented, no delta transforms, no constraints or axis locks on transformation.

Any suggestions would be greatly appreciated.

If the slider is greyed out, it could be that you have accidentally pushed this pin icon:
