Hi, I'm very new to POV-Ray so i've been looking at the reference docs to find
out what I can do. this code is present in the docs:

pigment {
  brick pigment{Jade}, pigment{Black_Marble}
  }

but i can't seem to get it working in a file. here's an example:

#include "colors.inc"
#include "textures.inc"
#include "shapes.inc"

background { color Cyan }
camera {
  location <0, 2, -3>
  look_at  <0, 1,  2>
}
sphere {
  <0, 1, 2>, 2

 pigment {
   brick pigment{Jade}, pigment{Black_Marble}
 }

}

light_source { <5, 30, -30> color White }



the render fails and it leaves this error:

File 'firstimg.pov' line 13: Possible Parse Error: Unmatched {
File 'firstimg.pov' line 14: Parse Error: No matching }, pigment identifier
 found instead
Fatal error in parser: Cannot parse input.


I can't get the brick pattern to work with two pigments, so i'm kind of confused
here, especially since this code was copy-pasted from the docs. Could I get some
help with this? Thank you (:

This appears to be an error in the documentation, as there is no such
pigment Black_Marble.  Try Red_Marble, White_Marble, or Blood_Marble.

Also, if those things are textures, you may have to use texture {brick ....} in
order for it to work properly.

Jade is a pigment, defined in textures.inc.  Black_Marble is not defined
anywhere, but there are 3 other marble pigments defined in textures.inc.
 No 'texture' keyword is needed.
