Hi

I've always used a default texture in a development scene. I also
prefer to use ramp_wave with wood. I don't understand why I have'nt
seen this problem before :(  Anyone tell me if I've got a script error
here please?

This occurs in Pov 3.0, 3.1 and 3.5 under Win98SE.

      wood
      color_map{[0 red 1][1 rgb <0,1,1>]}
      ramp_wave  // Disable this line to clear the problem.
   }
}

Would seem to be caused by the checker pattern, which doesn't accept a wave
form in the first place. Therefore it can't be overridden, however, looks
like a fix might be needed for that in #default if it's ever to be used in
that way. Either that or a mention of checker and brick (block patterns) not
being 100% workable as a default pigment.
Note that 'tiles' is already mentioned in the Scene Help as being
disallowed.

BTW poly_wave 1 behaves the same as ramp_wave but the float alters the
effect. I can't see anything in the docs. Only too pleased I hadn't
made a silly mistake :)

If there are no other responses I'll post it in beta-test incase its
something new.
