flash preloader in unity web player

Do you mean a placeholder animation using Flash or a quickly loading unity scene that loads immediately when the rest of the game streams?

I want a place holder animation using flash. Which is loaded before the unity webplayer game is loaded.

There's a forum thread with an example on what you want to do, here: http://forum.unity3d.com/threads/145294-Flash-Custom-Splash-Screen-Single-SWF

I went through the tutorial, but it loads a flash custom splash screen with a flash unity swf. $$anonymous$$y sponsor wants a custom flash preloader with a unity WEB player. Basically load a .swf splash screen file first then after that a .unity3d game file
