I'm not *sure* that the following idea or exact syntax would work, but it's
worth a try.
For your 'darker' texture, pre-#declare it like this:
#declare T_Stone29_DARK =
texture{
average
texture_map{
[1 T_Stone29]
[1 pigment{rgb 0}] // simply black
}
}
Then you can vary the 'weight' of the black pigment in the average, to get a
darker shade of T_Stone29 (instead of 1, maybe 0.5, etc.) Then use both of the
#declared textures, in whatever way you need to, on the object.
I admit that this is a rather crude way of getting such a result.
Personally, I *would* hand-edit the original texture instead-- by simply
reducing its finish{diffuse...} value-- then re-#declare it as a separate
texture.
