[away3d] problem with light in Away3d 3.5

[Sylvain Godbert]

Hi,

I made an animation that uses a mesh with ShadingColorMaterial. The
light is a directional light. In the onEnterFrame I change the
direction of the light like this :

_LightRot++;
_Light.direction.x = Math.cos(_LightRot/20);
_Light.direction.z = Math.sin(_LightRot / 20);
_View.forceUpdate = true;
_View.render();

But unfortunately this does not move the direction of the light. It
seems that once the direction of the light is set there is no way of
changing it.

Any idea to get this woking ?

Cheers

Sylvain
