Hi,
Here's my problem:
I have a macro in an include file ("textures_JeuM_v3.inc") defined like this:
#macro
T_var_Wrinkles(multiplicateur,Cmarron1,Cmarron2,Cmarron3,Cmarron4,Cmarron5,ValAmbient,ValDiffuse)
texture{pigment{wrinkles color_map{
[0.0 Cmarron3*multiplicateur]
[0.125 Cmarron2*multiplicateur]
[0.25 Cmarron1*multiplicateur]
[0.375 Cmarron2*multiplicateur]
[0.5 Cmarron3*multiplicateur]
[0.675 Cmarron4*multiplicateur]
[0.75 Cmarron5*multiplicateur]
[0.875 Cmarron4*multiplicateur]
[1.0 Cmarron3*multiplicateur]
}
scale 0.005
}
finish { ambient ValAmbient diffuse ValDiffuse}
}
#end
//Definitions des sols marron avec les macros
#declare T_marron_MacroNiv1 =
T_var_Wrinkles(<1,1,1>,C_marronA1,C_marronA2,C_marronA3,C_marronA4,C_marronA5,1,0)
#declare T_marron_MacroNiv2 =
T_var_Wrinkles(<1.12,1.1,1.1>,C_marronA1,C_marronA2,C_marronA3,C_marronA4,C_marronA5,1,0)
#declare T_marron_MacroNiv3 =
T_var_Wrinkles(<1.32,1.3,1.3>,C_marronA1,C_marronA2,C_marronA3,C_marronA4,C_marronA5,1,0)
#declare T_marron_MacroNiv4 =
T_var_Wrinkles(<1.52,1.5,1.5>,C_marronA1,C_marronA2,C_marronA3,C_marronA4,C_marronA5,1,0)
Below the macro definition you can see several callings of this macro that
define themselves a new texture.
And in the main scene file/pov file , I have this code:
#version 3.7;
global_settings{assumed_gamma 2.0}
#declare Anim_Serie=true;
#declare xN=128;
#declare HeightField=true;
#declare Mesh=false;
#declare Photo=true;
#include "textures_JeuM_v3.inc"
#declare T_transition1_2 = texture{gradient y texture_map{[0.0
T_marron_MacroNiv1][0.1 T_rocheGriseA2][0.9 T_rocheGriseA2][1.0
T_marron_MacroNiv2]}};
#declare T_transition2_3 = texture{gradient y texture_map{[0.0
T_marron_MacroNiv2][0.1 T_rocheGriseA2][0.9 T_rocheGriseA2][1.0
T_marron_MacroNiv3]}};
#declare T_transition3_4 = texture{gradient y texture_map{[0.0
T_marron_MacroNiv3][0.1 T_rocheGriseA2][0.9 T_rocheGriseA2][1.0
T_marron_MacroNiv4]}};
camera{
orthographic
location <0.000001,20,0>
look_at <0,0,0>
direction -y
sky z
up 2*z
right 2*x
}
height_field{png
#if (Anim_Serie=true)
#if (tps>=0 & tps<4)
"HF_x128_lineaire1"
#end
#if (tps>=4 & tps<8)
"HF_x128_lineaire2"
#end
#if (tps>=8 & tps<12)
"HF_x128_coin1"//Orniere
#end
#if (tps>=12 & tps<16)
#end
#end
#end
smooth
translate <-0.5,0,-0.5>
rotate 90*tps*y
#end
scale <2,1,2>
texture{T_transition1_2}
scale <1,4,1>
no_shadow
}
When I render this scene I expect to get images (with an ini file) with
different height_fields with the macro textures, alas this doesn't work ,
because
all the images are entirely black. I have no error message when I start the
render. I think something must be done with the macro but I don't know what.
Antoine.

Don't be offended but do you have any lights in your scene?
Also have you looked at the message pane and are there any clues there?

Yes , I have a light statement below:
#if (Photo =true)
camera{
orthographic
location <0.000001,20,0>
look_at <0,0,0>
direction -y
sky z
up 2*z
right 2*x
}
#else
camera{location <2.5,4,2.5> look_at <0,1,0>}
#end
light_source{<10,20,10>*100 color rgb 1}
height_field{png
#if (Anim_Serie=true)
#if (tps>=0 & tps<4)
//Etc..
I make a series of renderings to make image maps (the camera is orthographic)
And for example the message pane of the 11th image :

The other thing that sometimes gets me is my camera is not pointed at
the object. Until one of the smart people answers, you could try
changing your camera to a wide angle perspective one to make sure your
camera is pointed at the object.

When I posted the first message of this topic, I was on my laptop and it didn't
worked. Whereas now on my desktop PC it works fine. Something must be wrong...
:(
I will put the desktop PC files on my laptop and see if it work or not.
Thank you for your help Stephen. :)

You have given us insufficient information to test the scene. What are the
values of C_marronA1, etc.? What is the value of tps? What do the height field
source images look like?

You can help us help you quite a lot by posting complete scene files
(*), rather than just posting what you /think/ are the relevant portions
of the scene.
For instance, my personal approach to troubleshooting your scene would
be to just load it into POV-Ray, check that I can reproduce the symptoms
you're describing, and then toy around with the scene, following some
spontaneous trails of intuition. But I can't do this now, because I'm
not sure what exactly your scene is: It seems to have evolved since your
first posting, and apparently neither posting contains a complete scene.
Also, do you even still get a black output, now that you have added a
light_source? And what is the height field image? The exact shape of the
height field may turn out to be relevant for the problem as well.)
(* Note that you're welcome to simplify your scene and trim it down to
the portion that gives you problems; that, too, helps us help you. You
may also substitute a simpler height field image in this process,
provided you can reproduce the problem with that image. But once you're
done with that, I really recommend posting the resulting trimmed-down
scene in its entirety.)

One thing that I would try:
First, #declare your object.
Next, find it's bounding box using min_extent() and max_extent().
Average the returned values.
Use that averaged value as the look_at for the camera.
If you still get nothing:
Maybe the object is to small or large or to distant.
Try moving the camera toward the object or the object toward the camera.
Try scalling the object up or down. Start using factors of 10.
Maybe it's to dark.
Try any of the following:
Use a white background.
Use only ambient and temporarily set the colour to some light shade,
like rgb<1,0,1>.

relatively dark and warm.
So, the various C_marronxx are variations of that brown.
