Can a 3D model have opacity 0 & why always on top?

[rst77 webforumsuser@macromedia.com]

I'm working on a 3D menu which is based on a molecular structure. I have manged to give each sphere of the structure a navigation mousedown. But when an item is selected, i would like to fade the menu (3D morld) away, so the content can come in in a smooth way.

I just don't know where to achieve that. I know that it must be something with the lingoscript "blend", but where? And how can I control exactly when the menu will fade in and out? Should it be linked to a mouseclick, or maybe in a behaviour?

Then another question, why is it that a 3D world cannot be arranged to the back? It seems to be always in front of everything, no matter wich channel you use for the model.

Thanx in advance and a happy 2004 to you!

Actually, you cannot display another sprite on top of the 3D scene, even
with a higher priority, unless you disable the W3D sprite directToStage
property, at the cost of performance. No need to say disabling DTS is not an
option, or may be you can do it by code at the end of your interface fade
out (performance will not be an issue then).

For the fade in/out of the interface, you must use the blend property of
shaders.

For this, you can either use the 'FadingModel' parent script (create an
instance by code in a movie script or frame script) or the 'Transparency
Tweening' behavior in the Chrome Lib:

Thanx for your reply,


I've downloaded the files you suggested, i'm sure it will be a lot of help!
I should have posted my question earlier, these library files would have saved me a lot of time.
