Color lookup tables and ambient lighting

[jnorris at uiuc.edu]

Hello all,

I'm using a recent nightly release of VTK 2.4.  I'm rendering an actor using
a lookup table in the mapper.  I want to increase the ambient lighting so
that the shadows aren't as dark, but apparently the lookup table isn't
consulted when it comes to ambient properties.  For instance, if I SetAmbient
to 1 in the actor properties, I'd expect the actor to have bright colors and
no shadows.  Instead, the actor becomes solid white.  Is this the desired
behaviour?  Am I missing a setting somewhere that causes the renderer to use
the lookup table when using ambient light?

Thanks,
John
