[vtkusers] Lighting problem

[Paul Tait]

More info to perhaps pique your interest

I'm moving my actors around with actor->AddPosition(0, 0, deltaZ)

I can see the bottom of my actors but as soon as I get above the
horizontal its as if the lights switch off.  This only happens AFTER
I've used actor->AddPosition(0, 0, deltaZ) Before that I can view them
from any angle.

I've just modified my VTK app to accentuate the vertical distances
between some oil reservoirs. Everything goes fine till  start moving the
model around. From many angles the it just shows black. By moving around
to another position I can see it again. I'm using a plain vtlLightKit
which normally works really well for me. Do I have to inform it or
something else of the change in the scene ?

PS Wil... Hows my high contrast LUT coming on ?
