[Papervision3D] Collada + ShadedMaterial....

[Rob Langston]

Hey, Tim --

Sorry to resurrect this topic, but I'm having the same issue with a  
Max3DS object and EnvMapMaterial.  Any hints on how to fix?  Thanks.

TypeError: Error #1009: Cannot access a property or method of a null  
object reference.
	at org.papervision3d.materials.shadematerials::EnvMapMaterial/ 
drawTriangle()
