Can Alpha value change between two Keyframes ?

Hi

Flash CS5.

I have a MovieClip Spatter set to Alpha 21% in one keyframe and a few secs later along its layer on the timeline another KF with it set to 1%

I run movie and it stays at 21% until it gets to the second KF when it suddenly becomes 1%

I right click between the two KFs and choose Classic Tween, still no difference.

Undo that and try for a Motion Tween, ok the con to symbols prompt. still no joy.

Try for Classic Tween again with...

I see a Blending option so alter that to Alpha for both MCs at the KFs,. no better,

 

How do I get the alpha value to change continually and progressivly from 21% to 1% across lets say 3 secs, so that after 1 sec its 14% then after two secs its 7% etc.

 

The MC itself is a 5 frame duration, each frame is a KF with whiteSpatter on a transparent base as a .png the size of which gets larger with each KF. So a growing spatter effect.

 

I need to fade this over a period of say 3 secs in my scene1 movie. I am successful in moving it at a steady single alpha value 21% across my scene, but I need the alpha to change during the move to become 1%.

    If it is a movieclip symbol (or a graphic symbol) you can tween the alpha value between keyframes using a motion tween.  I would use a classic tween because I have not used the newer one.  If this is not working for you then chances are you are not setting things up correctly.

    When tweening on the timeline you can only have one object involved and that object has to be the same object from the first to the last keyframe.
