1.- As you can see in the picture, in a propertly like Volume (in example), if I click over the value, a number box appears waiting for a figure be entered and a little arrow at left appears too.
2.- Then I press that arrow inside the little square and now I can choose between three options:
- The "Arrow" (for Use cache or other action's value (¿...?))
- A "Padlock" (for Constant value).
- And a "Watch" (for Time-based value).
4.- But... then I make changes in the value over the time and any keyframe is created and the propertly is always the same in time
So... I'm obviously misunderstanding something here and, of course, I want to know! Someone knows the truth about this (to me at least) little mystery? Well, I hope... And THANKS in advance if so!
