Allowing a object to fade in and out from certain coordinates?

Hi all,

I am looking for a way to make a object fade in our out from a certain point. So in other words i have a objects that is a 100 by 100, and I want it to fade in at (50, 50) so that at first the middle of the image becomes more visible and then the edges slowly become more visible but the center is the faded in first. Does this make any sense ha? Sorry I know my explanation probably isn’t the best. Any help would be great thanks.

Best,

There is no standard way to do this. alpha applies to the whole object. But what you could do is cover the object in concentric opaque circular or thick rectangular outlines and change their alphas in whatever sequence you want to “reveal” it. Or make a group of it with another, overlaying, image which is a small transparent circle that fades to black, put a mask on the group so the image is contained, them transition-size the overlaying image so that the transparent part is sized bigger and bigger, revealing the underlying image…

You get the idea. [import]uid: 160496 topic_id: 30535 reply_id: 122343[/import]
