View Full Version : Cut object to surface image alpha channel?

05-13-2005, 08:23 PM

I have a logo I'd like to animate in layout. I've created a square, and placed it on the surface, but I'd now like to trim off the part of the object outside of the logo. The image has an alpha channel, so I was hoping there was an easy way to use that.

Any suggestions?

Here's an idea and pehaps someone will post an easier way, but hopefully this will do what your asking.
Take your logo and render out an alpha sequence of just the logo. Apply this sequence as a clipmap to the square. Not sure whether black or white is what hides the object, so it may be necessary to invert the sequence.
Hope this works, and maybe someone else will explain an easier way, as I love to learn simpler ways, especially when they work. :rolleyes:
