hmm, you probably need to restrict shadow calculation to an area of
interest, i.e. around the walking machine or (part of) the camera frustum.
That goes beyond what the SimpleShadowMapEngine can do at the moment.
You could use it as a starting point and give it an additional field
that stores the root of the shadow casting scene which would then be
used to calculate the projection for rendering a shadow map -
SimpleShadowMapEngine::setupCamera() is where this is calculated.
Cheers,
Carsten
