I would appreciate it if someone were able to make a suggestion here.

I'm in a position where I need to fade a view of a scene to black. I'm
used to using the OpenGL calls to set the pixel transfer scale factors
to my required colour scale. If I do this in Performer 2.0 it looks like
textured objects are the only ones to be scaled.

Is there any Peformer equivalent, or has anyone found a sensible
alternative?

At the moment I am trying the approach of scaling the light intensities
but this is beginning to get messy since I need to follow various
material properties and more.

The application is intended to work with any geometry presented to it.

Any advice would be appreciated,
Thanks,

Graham Jones.
