Alpha gradient banding

Hello

 

I've created a shape that has a gradient fill. From 100% alpha to 0% alpha. When I overlay it on a solid of the same colour, I can see banding from where it starts to graduate.

I want to tween the shape. But the effect I'll get is of the banding area in the shape moving...

The image is attached for reference.

Any suggestions, please?

Hello. I can see the gradient when it's just a shape, and also as a graphic symbol.

to tween your shape, you must first convert it to an object. eg, movieclip (or graphic).  then apply the tween.

I've attached a test file. The bit that bothers me is where the alpha changes from 100 to 0. The area appears darker. Is there a way around this?

i don't see a problem (other than you're moving too many pixels in that time span) causing visual artifacts.
