I have to agree with you, but as monotonous as it might sound, the key to
mastering anything is practice. Don't think H.E. Day became an H.E. Day
overnight... He's spent hundreds of hours refining his skills over the
course of several years...
Still a tutorial would be nice...or at least a tip towards the method behind
the madness.

Tutorial ?.. you got it :-)
How to make a real good object in few steps :
1 - Create a file like this :
// Standard includes
#include "color.inc"
#include "textures.inc"
// Camera stuff here as you want
camera {
.../...
}
// Light source here as you want
Light_source {...
.../...
}
// H.E.Day includes
#include "new_textures.inc"
#include "big_textures.inc"
#include "amazing_tex.inc"
#include "incredible_tex.inc"
#include "crazy_tex.inc"
#include "more_stuff.inc"
#include "even_more_crazy_stuff.inc"
#include "I_dont_understand_tex.inc"
// Personal object
object {
sphere { <0,0,0> 1 }
rotate <17,23,47> // Just to show I understand something...
texture {
H_E_Day_tex // Put here a name (whatever it is called, H.E.Day made it..)
}
}
// End of file
Step 2 : render... It will take a few hours or days, but the result will be really
awesome, as usually when using H.E.Day textures....
Step 3 : post it on pbi and say 'Look !... I made this !...'
Question : do I have understood something ?...

Ironically, you're not far from the truth.
Here are the texture declares I use:
#declare Scarring =
texture {pigment {bozo color_map {[0 rgb .175 transmit .75][1 rgb .175 transmit
1]}scale 2}}
texture {pigment {bozo pigment_map {[0 bozo color_map {[0 rgb .125 transmit .75][1 rgb
.125 transmit 1]}scale .125][.5 rgb .175 transmit 1]}scale 2}translate 25}
#declare Rusting =
texture {pigment {bozo color_map {[0 rgb <1,.5,.4> transmit .75][1 rgb <1,.5,.4>
transmit 1]}scale 2}}
texture {pigment {bozo pigment_map {[0 bozo color_map {[0 rgb <1,.5,.4> transmit
.75][1 rgb <1,.5,.4> transmit 1]}scale .125][.5 rgb .175 transmit 1]}scale 2}translate
25}
#declare Rusting2 =
texture {pigment {bozo color_map {[0 rgb <1,.5,.4> transmit .875][1 rgb <1,.5,.4>
transmit 1]}scale 2}}
texture {pigment {bozo pigment_map {[0 bozo color_map {[0 rgb <1,.5,.4> transmit
.875][1 rgb <1,.5,.4> transmit 1]}scale .125][.5 rgb .175 transmit 1]}scale
2}translate 25}
#declare Dirt =
texture {pigment {bozo color_map {[0 rgb <.6,.5,.4> transmit .75][1 rgb <.6,.5,.4>
transmit 1]}scale 2}}
texture {pigment {bozo pigment_map {[0 bozo color_map {[0 rgb <.6,.5,.4> transmit
.75][1 rgb <.6,.5,.4> transmit 1]}scale .125][.5 rgb <.6,.5,.4> transmit 1]}scale
2}translate 5}
#declare Chipping =
texture {
pigment {bozo pigment_map {[.4 bozo color_map {[.2 rgb 1 transmit .125][.3 rgb 1
transmit 1]} turbulence 1/2 scale .125/2][.5 rgb .175 transmit 1]}scale 8}
}
#declare Chipping2 =
texture {
normal {bozo normal_map {[.4 bozo normal_map {[.2 bumps scale 1/16/12 bump_size
1/12][.3 bumps scale 1/8 bump_size 0]} turbulence 1/2 scale .125/2][.5 bumps scale 1/8
bump_size 0]}scale 8}
pigment {bozo pigment_map {[.4 bozo color_map {[.2 rgb 1 transmit .125][.3 rgb 1
transmit 1]} turbulence 1/2 scale .125/2][.5 rgb .175 transmit 1]}scale 8}
}
#declare Chipping3 =
texture {
pigment {bozo pigment_map {[.4 bozo color_map {[.2 rgb 1.5][.3 rgb 1 transmit 1]}
turbulence 1/2 scale .125/2][.5 rgb .175 transmit 1]}scale 8}
}
I take these and layer them on, just like in the real world. Here are some examples:
//Concrete Pavement Texture
pigment {rgb 1}
normal {dents scale 1 turbulence 1 bump_size 1/3}
finish {ambient .1 diffuse .9 phong .05 phong_size 2 crand .05}
texture {Scarring scale <1,4,4>}
texture {Scarring scale <1,4,4> scale 2}
//Adobe-like building texture:
pigment {rgb <1,.95,.9>}
normal {dents scale 1/4}
finish {ambient .1 diffuse .9 phong .05 phong_size 2 crand .1}
texture {Scarring scale 4*y}
texture {Scarring scale 4*y scale 2}
texture {Rusting2 scale 2*y scale 1/2 translate 20}
texture {Chipping scale 1/4}
texture {Rusting scale 2*y scale 2 translate -20}
//Signpost Texture:
pigment {rgb <.875,1,.8755>}
finish {ambient 0 diffuse 1 phong .25 phong_size 10}
texture {Scarring scale 4*y}
texture {Chipping scale 3/4}
texture {Rusting translate 45 scale 4*y}
// A nice, frothy water texture.
pigment {rgb <.05,.1,.075>*2 transmit .25}
normal {granite .25
phase clock
translate -5*x*clock
scale <1,1,4>*10}
finish {ambient 0 diffuse 1 phong 2 phong_size 200 metallic reflection .5
conserve_energy}
scale 2/3
}
texture {Chipping}
texture {Chipping2 scale 2}
texture {Chipping2 scale 4}
texture {Chipping3 scale 4 translate 20}
texture {Chipping3 scale 4 translate -20}
texture {Chipping2 scale 6}
interior { ior 1.33 media { absorption rgb (1-<.8,.9,1>)*50 method 2 }}
The sky is the limit. Remember that there are no clean textures. Every one should
have at least one {Scarring} texture applied to it.
Oh, By the way, these texture samples come from my next IRTC entry. Please no one use
them to oust me, hmmm?
Good luck!

Well... my little finger told me.... :-)

Yes... I use your Scarring texture on my object as a second layer... :-)

He ?... I'm right after all...

Stills or Animations ?...
Personally, I'm not good enough to post something for irtc... ;-/
Maybe later...
> Good luck!
The other competitors need luck !.... :-)))
