I seem to recall Mr. Dodd (I think) discovering that it makes a big
difference if you have the same height value in your material as you do
on the spec tab of the object properties...

Hi Chris..and all..
You might already done this..
but I mention it again..
Instead of setting Bumpheight value just to a positive range..
Like this -> 0 to 0.2
Have the Bumpheight value in the material(s) evenly spread around 0...
Like this -> -0.1 to 0.1 and then set your Displacement value in the
object(s) to 0.1 (As you notice you only now need half the value for
the Disp Val..and this should in most cases then at LEAST cut the
render times into 1/2 =)
Take Care

Yes, this was my first error when I started using displacements,
however it
is not the problem I now face. The whole process just seems to be
very slow,
unless there is something else I am missing
Thanks,
Chris
My first guess is to make sure, that the amount of the displacement
(as defined in the property tag) is set to the appropriate size.
Meaning, if you displace a surface by a centimeter, the max
displacement value should be set to that amount as well, and not
higher.. that will conserve resources.
Hope that helps.
