I created a scene with a macro, and inside that macro I use a blob. I believe I
declared the things correctly, but I cannot render the scene. Instead, I always
get the error message:

"Parse Error: Object identifier expected"

And here's the sample:

// Full Hull
#macro Full_Hull(ShowTexture)
blob
{
 threshold 0.04
 sphere // Upper Hull
 {
  < 0.0, 0.0, 0.0 > 1135.0, 1.0
  scale < 10.0, 1.0, 1.0 >
  translate < 0.0, 750.0, 0.0 >
 }
 sphere // Lower Hull
 {
  < 0.0, 0.0, 0.0 > 1135.0, 1.0
  scale < 10.0, 1.0, 1.0 >
  translate < 0.0, -750.0, 0.0 >
 }
 sphere // Middle Hull
 {
  < 0.0, 0.0, 0.0 > 1135.0, 3.0
  scale < 6.0, 1.75, 1.0 >
 }
 sphere // Flat Disk-Alike Sphere
 {
  < 0.0, 0.0, 0.0 > 1500.0, 1.0
  scale < 2.0, 0.5, 1.0 >
 }
 sphere // Smaller Field-Generator-Carrying Ellipsoid
 {
  < 0.0, 0.0, 0.0 > 1500.0, 1.0
  scale < 1.0, 0.15, 1.25 >
 }
 #declare Random_1 = seed(2); // Plus_X
 #declare Random_2 = seed(7); // Sphere Diameter
 #declare Random_3 = seed(3); // Sphere Height
 #declare Random_4 = seed(9); // Sphere Translate
 #declare Line_X = -6100.0;
 #while (Line_X < -800.0)
  #declare Trace_Start = < Line_X, 0.0, -2000.0 >;
  #declare Trace_Direction = < Line_X, 0.0, 0.0 >;
  #declare Trace_Norm = < 0.0, 0.0, 0.0 >;
  #declare Sphere_Diameter = RRand(75, 150, Random_2);
  #declare Sphere_Y = RRand(0.25, 0.50, Random_3);
  #declare Translate_X = Line_X-1500;
  #declare Translate_Y = RRand(0, 250, Random_4);
  #declare Translate_Z = trace (Pseudo_Hull, Trace_Start,

  sphere // Middle Constructions (-X +Y -Z)
  {
   < 0.0, 0.0, 0.0 > Sphere_Diameter, DarkPower
   scale < 1.0, Sphere_Y, 1.25 >
   texture { Middle_Constructions }
   translate < Translate_X, Translate_Y, Translate_Z >
  }
  sphere // Middle Constructions (-X +Y +Z)
  {
   < 0.0, 0.0, 0.0 > Sphere_Diameter, DarkPower
   scale < 1.0, Sphere_Y, 1.25 >
   texture { Middle_Constructions }
   translate < Translate_X, Translate_Y, (-1*Translate_Z) >
  }
  sphere // Middle Constructions (+X +Y -Z)
  {
   < 0.0, 0.0, 0.0 > Sphere_Diameter, DarkPower
   scale < 1.0, Sphere_Y, 1.25 >
   texture { Middle_Constructions }
   translate < (-1 *Translate_X), Translate_Y, Translate_Z >
  }
  sphere // Middle Constructions (+X +Y -Z)
  {
   < 0.0, 0.0, 0.0 > Sphere_Diameter, DarkPower
   scale < 1.0, Sphere_Y, 1.25 >
   texture { Middle_Constructions }
   translate <(-1 *Translate_X), Translate_Y, (-1*Translate_Z) >
  }
  sphere // Middle Constructions (-X -Y -Z)
  {
   < 0.0, 0.0, 0.0 > Sphere_Diameter, DarkPower
   scale < 1.0, Sphere_Y, 1.25 >
   texture { Middle_Constructions }
   translate < Translate_X, (-1*Translate_Y), Translate_Z >
  }
  sphere // Middle Constructions (-X -Y +Z)
  {
   < 0.0, 0.0, 0.0 > Sphere_Diameter, DarkPower
   scale < 1.0, Sphere_Y, 1.25 >
   texture { Middle_Constructions }
   translate < Translate_X, (-1*Translate_Y), (-1*Translate_Z) >
  }
  sphere // Middle Constructions (+X -Y -Z)
  {
   < 0.0, 0.0, 0.0 > Sphere_Diameter, DarkPower
   scale < 1.0, Sphere_Y, 1.25 >
   texture { Middle_Constructions }
   translate < (-1 *Translate_X), (-1*Translate_Y), Translate_Z >
  }
  sphere // Middle Constructions (+X -Y -Z)
  {
   < 0.0, 0.0, 0.0 > Sphere_Diameter, DarkPower
   scale < 1.0, Sphere_Y, 1.25 >
   texture { Middle_Constructions }
   translate <(-1 *Translate_X), (-1*Translate_Y), (-1*Translate_Z) >
  }
  #declare Plus_X = RRand(75, 150, Random_1);
  #declare Line_X = Line_X + Plus_X;
 #end
 #if (ShowTexture=yes)
  texture { Hull_Texture_Side scale 20000.0 translate < -10000.0, 0.0, 0.0 > }
 #end
}
#end

------------------------------------

And I am calling the macro this way:

#macro Cut_Hull(ShowTexture)
difference
{
 object { Full_Hull(ShowTexture) }
 .
 .
 .
}

------------------------------------

And that one I call this way:

#declare Ship = union
{
 object
 {
  Cut_Hull(yes)
 }
 .
 .
 .
}

Any ideas what I'm doing wrong? Thanks.
