There is a bug in bump_maps in POV-Ray 3.1d which was just released.

Don't download it if you need bump maps.

For you compile-it-yourself folks...

try changing image.c line 362 from...

  VScaleEq(yprime, bump_normal[Y]);

to

  VScaleEq(yprime, (-bump_normal[Y]));

That fixed it for me but let's let the troups beat on it more just to
make sure before releasing 3.1e officially.

Well!  I want my money back!!  :)



That's funny, negate just [Y] but not [X] or [Z]?
