#Bump map render glitch
I have created an Asphalt material, default with an image of road
aspalt as texture and bump map entries. I am panning around this road surface,
and in certain frames, rendering in any resolution
and palette combination, dithering and other settings in any combination
produces wild "flashes", jaggy torn blocks of lighter or darker coloration as
the camera pans around this "bumpy" surface. I am at a
loss: I understand that I might have expected some interference patterns
if these bumps were being treated as actual surface features (as with
a CD-ROM surface) but these jaggy flashes don't really seem to conform
to any pattern, or order, nor do they seem to change consistently as
the road and camera change angles with respect to one another: it just seems
that certain frames insist on having great blotches of dark or bright.
I am at a loss.. if anyone has a thought, I would be delighted to be
rescued.
