I have improved the rendering speed of objects with blurred reflection and
radiosity.  In order to see this improvement:

- You must use macro RC3Metal_Blur() or RC3Metal_Normal_blur().
  The improvement does not apply to macros RC3Metal_Blur_t() and
  RC3Metal_Normal_blur_t().

- You must use POV-Ray 3.7 or later for any significant speedup.

Theoretically, there should be a slight speedup for non-radiosity and pre-3.7
scenes, but said theoretical speedup is too insignificant to notice.

Thanks! Very Good! But...
Update rc3metal.inc:

#macro RC3Metal_Galvanized_t (c_Dull, c_Shiny, Dull, Shiny, Dark, Light, Shine,
Turb, Scale)
  #if (RC3M_Debug) #debug "RC3Metal_Galvanized_t()...\n" #end
  texture
  { crackle solid texture_map
    { [0 RC3Metal (c_Shiny, Shiny, Light)]
      [Shine RC3Metal (c_Dull, Dull, Light)]
      [1 RC3Metal (c_Dull, Dull, Dark)]
    }
    turbulence Turb
    scale Scale
  }
#end

Scaling crackle is required surely!  :)

Scaling can be easily achieved this way:

#declare T = RC3Metal_Galvanized_t (...)
texture { T scale MyScale }

Unfortunately, this syntax is not accepted for turbulence, so I will consider
your suggestion.

One bald person (he was called Lenin) spoke:

Thanks!   :))))))))
