Hey guys

I’ve been googling this for about two hours and coming up seriously short.

In AS3 using Tweener, I’d like to be able to tween the height of a plane in Papervision. However, using the following (where p is the Plane):

```php
 
Tweener.addTween(p, { height:moveTo, time:1} );

```

I get ‘Property height not found on org.papervision3d.objects.primitives.Plane and there is no default value’; so while you can define the height as an argument when defining a plane, you can’t access it later.

Does anybody have any suggestions on how to do this? It’s driving me to distraction 😕
