[Animation] Tweenable Fade - RealWorld forums

http://bit.ly/1b5Dlbi
Download the above link and drag the file onto a toolbar in Animation mode.

It allows you to select 2 or more frames and then fade from one value to another across the selected frames.
For each frame it times the alpha values for pixels by that amount.
Use it with the Tweenable Blur for some cool fade in/outs.
You can also select a Tween mode.
For those dont know what that is check this page....

But just playing with the thing will give you the idea

Speed
Great!
Doesn't have any per pixel processing and uses all RW commands so its nice and zippy.
