Intresting, and yes it will work but with a few buts.
First you will need to do the color-declaring before you do your model. And
you have to (well, not "have to" but is saver to) "undeclare" (or undef) the
old color definition.
This syntax works:
0 L3P IFPOV
0 #undef Color384 // just to be sure
0 #ifndef (Color384)
0 #declare Color384 = #if (version >= 3.1) material { #end texture {
0 pigment { rgb <0.8,0.5,0.15> }
0 finish { ambient 0.45 diffuse 0.85 }
0 finish { phong 0.5 phong_size 40 reflection 0.5 }
0 #if (BUMPS) normal { BUMPNORMAL } #end
0 #end
0 } #if (version >= 3.1) } #end
0 L3P ENDPOV
1 10 0 0 0 1 0 0 0 1 0 0 0 1 4198.DAT
1 384 140 0 140 0 0 1 0 1 0 -1 0 0 4198.DAT
0
Again, I used #undef to clear the old definition (line 2) and line 3 checks
if there already is a definition for Color384.
Line 3 to 10 is copied from the normal L3P/POV color-definition. You can add
or change parameters if you want. After the ENDPOV the LDraw model starts.
Good idea Dave!!!
