How can I write a macro that creates a layaered texture, since

#macro foo
texture {}
texture {}
#end

#declare mytext1 = foo()

is a syntax error (it works fine with one texture in foo)

   #end

Hi Jaime,

this looks very fine. I understand why you use #local t_result,

But why #local dummy=0; is there????

Pascal.

   It's just to avoid POV-Ray interpreting the result as the 3rd layer 
of the declared texture. :)
