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!
