Hi again,
I've managed to avoid the exception.
I think there is a bug in View3D.as: In render method there is no
check for null context before calling updateLights and
renderSceneDepth.
Here is the modification I made in View3D.as:
Before (at line 317):
updateLights(_entityCollector);
if (_requireDepthRender)
renderSceneDepth(_entityCollector);
After:
if(context)
{
updateLights(_entityCollector);
if (_requireDepthRender)
renderSceneDepth(_entityCollector);
}
After making this change a new exception arises at
popModelViewProjection in Entity.as, caused by the call to
_entityCollector.cleanUp() at line 338 in render method:
RangeError: Error #1125: The index 1 is out of range 1.

To solve it I've added a check before decreasing _mvpIndex:
public function popModelViewProjection() : void
{
if(_mvpIndex>0)
--_mvpIndex;
}
I think this deserves a deeper insight because there are more pops
than pushes, something misssed there.
With these changes I have removed the exception but the shadows
continue rendering in software mode.
Hope this helps.
