interactive (adding listeners to) DAE model in flex + papervision

I have a DAE model that is parsed into several parts. I am able to deal with them separately, such as changing their ma开发者_开发技巧terial or colour but I am having problems adding click or hover listeners over the children.

For example, lets say I have a model of a kitty where each facial feature is a child. I want to be able to hover or click the features and have a window pop up explaining the feature.

I've tried parsing the model and adding listeners but it doesn't seem to work.

Thanks in advance!

Hard to pin point the problem from your description, but you could check the following:

1. Make sure your viewport is interactive
2. Make sure the material your material is interactive
3. Make sure the DisplayObject3D you assign the listener to is not null.

Point 3, with collada objects, you can have nested objects, make sure you add a listener to an object that has geometry, not an empty(no geometry) container. With points 1,2, both viewport and material have a Boolean property called interactive which must be set to true for mouse events.
