I'm sure this is something I've seen somewhere in the manual, but I cannot
find it anywhere :(

I'm trying to create a kind of 3D relief map of the world, and have some
pretty image maps and height maps etc, and I want to make the water parts of
the map partially reflective.
I also have a black-and-white image with the water parts white and the land
parts black.

What I can't work out is how to make areas of the height_field{} have
different finishes depending on the value of the B&W mask.

I appologise in advance if this is an RTFM or RTFFAQ moment, but I have
tried, hones :o)

Many thanks,

Mark

texture_map/material_map with pattern based in that B&W mask/image ?

I'm sure there is enough keywords above to start interesting travel through
manual :-)

Check with the manual concerning material_map or material maps. Allows you
to place individual textures based on an image files pallete index number
(color).

The only way to get different finishes in POV-Ray 3.5 is to use 
different textures.

You can use different textures accoding to a mask image with a 
material_map or an image_pattern with a texture_map.

here is something i worked off of.
http://news.povray.org/povray.binaries.images/30764/

then scroll down (if your useing the web veiw of the newsgroups) to the
message from Gilles Tran.

here is an image i did based on the technique in Gilles' message
http://news.povray.org/povray.binaries.images/30995/

or alternately, seach for "finish maps" in the binaries.images group.
