I've had a similar problem just recently. I've just uploaded an example of it
called PRBLEM.GIF in the images library, if you're interested (wait for the
sysop to post it). I'm wondering if it's related to a glitch with ray-traced
shadow casting spotlights which go a bit screwy if they hit an object that is
self intersecting. The sea in the image had a bump map to simulate waves which
rendered ok in other views but went nuts in this one. The material is on a flat
plane but many of the objects I modelled penetrated the plane, rather than sat
on top of it. The heavy raster lines were introduced at rendering and I'm
wondering if this is related.
Sound similar?
Any ideas, anyone else?
