Hi,
I want to display a Collada model over top of a video stream and dynamically adjust its alpha value. Right now I have it partially working in PaperVision but I can't seem to set the alpha of the model at all. I have tried a few things from google. For non-Collada models the following works fine:
var layer:ViewportLayer = viewport.getChildLayer(myModel, true);
layer.alpha = 0.5;
All the Collada models I have tried have UVW mapped textures. In the end I am hoping to have the model alpha adjust continuously based on some external events. I have googled extensively and had little luck.
Any help would be appreciated!
UPDATE / RESOLVED
So as indicated below, all I needed to do was find the appropriate child and manipulate it directly. My code now looks similar to:
currentModel = new DAE(true, "Model");
currentModel.load("./model/Model.dae");
baseNode.addChild(currentModel);
currentModel.addEventListener(FileLoadEvent.LOAD_COMPLETE, function():void {
// Assume first child is what we want
for (var key:String in currentModel.children) {
currentModelContainer = currentModel.getChildByName(key)
currentModelContainer.useOwnContainer = true;
currentModelContainer.alpha = 0.0;
break;
}
});
Now, later on all I do is use Tweener to adjust the alpha attribute of currentModelContainer.
Cheers for the help! Hopefully this helps someone else in the future.
