Hi Andreas,
first I must congratulate you on the very nice and innovative rendering,
and thanks for providing the MPD together with instructions at Brickshelf.

It seems you have tweaked the L3P generated file manually.
I would like to draw you attention to that it can be done
directly in the MPD file, either manually or in MLCad.
If you do it in MLCad it is much easier to adjust scaling and translation
because you can see the effect immediately,
rather than using the slower PovRay.

The scaling and translation you (or Zach Best?) have done in the POV file:

object { lenin__shelf_dot_ldr matrix <1,0,0,0,1,0,0,0,1,-145,-122,20>
#if (version >= 3.1) material
#else texture
#end { Color12 } scale 0.32 translate <-206,-58,0>}

object { schneekugel_dot_ldr matrix <1,0,0,0,1,0,0,0,1,-145,-122,20>
#if (version >= 3.1) material
#else texture
#end { Color12 } scale 6 translate <650,662,-120> }

simply corresponds to an additional reference through a line type 1,
e.g. "scale 0.32 translate <-206,-58,0>" can be written as
1 16  -206 -58 0  0.32 0 0  0 0.32 0  0 0 0.32 xxx.ldr

In the MPD replace

1 12 -145 -122 20 1 0 0 0 1 0 0 0 1 lenin_shelf.ldr
1 12 -145 -122 20 1 0 0 0 1 0 0 0 1 schneekugel.ldr

with

1 12 -206 -58 0  0.32 0 0 0 0.32 0 0 0 0.32 lenin_shelf_trans.ldr
1 12 650 662 -120  6 0 0 0 6 0 0 0 6 schneekugel_trans.ldr
0
0 FILE lenin_shelf_trans.ldr
1 12 -145 -122 20 1 0 0 0 1 0 0 0 1 lenin_shelf.ldr
0
0 FILE schneekugel_trans.ldr
1 12 -145 -122 20 1 0 0 0 1 0 0 0 1 schneekugel.ldr

and you are ready for MLCad tweaking.

You can also combine the references into the even shorter

1 12  -252.4 -97.04 6.4  0.32 0 0 0 0.32 0 0 0 0.32 lenin_shelf.ldr
1 12  -220 -70 0  6 0 0  0 6 0  0 0 6  schneekugel.ldr

which is the effect of multiplying the two matrices.

It's always better to make changes in the source file (the MPD),
rather than change a generated POV file.
Then changes won't be lost next time you generate the POV file.

Posted on behalf of Andreas Weissenburg (2 URLs) I finished my second remix, it is a lenin in a snow globe. There is not much snow inside the globe, but that doesn' matter. Like Zach Best's in his entry I rescaled some objects (downsized the statue (...) (18 years ago, 13-Feb-06, to lugnet.cad.ray, FTX)
