Hi, guys.

Now I want to fade in and fade out different parts of a model by different keyboard event handlers. There is thousands of meshes in this model and each of them has a unique colormaterial, thus I put them into different group, namely different objectcontainer3d, and then want to tween the transparency of the container.

Here is the problem. I do understand there is no alpha property for objectcontainer3d in away3d, but meanwhile I don’t want to change the material alpha one by one. Becuase it’s very time consuming and not elegant…

So any good idea?
P.S. I just want to make the fade in and fade out effect, so any other solutions are welcomed!

Reminder…
Anyone has good idea???
Thanks in advanced!

this alpha setter for ObjectContainer3D would anyway be a for loop setting the alpha property to all of its children, no?

I think so too. But if it would be implemented in that way, I am quite not sure about its efficiency, which is also one of the reasons why I asked help here.
