I'm tinkering with the excellent hair macro by Chris Colefax and have run
into a problem. I don't have much experience working with macros so I am
probably overlooking something fairly obvious. The problem is that I have
two objects each with their own fur. The macro is not allowing me to
re-declare variables for different traits, but is instead reusing old
values.
#declare "pcmhair.mcr"
#declare hair_length = 0.2;
#declare hair_thickness = .005;
#declare hair_thickness_curvature = 1;
#declare hair_rotation = x*90;
#declare hair_sky = -z;
#declare hairs_per_patch = 150;
#declare hair_rotate_to_surface = true;
#declare hair_objects_per_unit = 750;
#declare apply_hair_materials_to_mesh = true;
#declare hair_rotation_turb = 0;
#declare hair_patch_turb = 0;
read_mesh ("pd1.pcm")
#declare hair_length = 1;
#declare hair_thickness = .05;
#declare hair_thickness_curvature = 1;
#declare hair_rotation = x*90;
#declare hair_sky = -z;
#declare hairs_per_patch = 20;
#declare hair_rotate_to_surface = true;
#declare hair_objects_per_unit = 5;
#declare apply_hair_materials_to_mesh = true
read_mesh ("pd2.pcm")
The hair on the second mesh is not 1 unit, but 0.2 like the first. Some
aspects I am able to control differently, but others, like the length, stay
the same. I tried putting these blocks in a macro and changing the declares
to locals but that did not help. Any ideas?
