Yea, seems to me that should do the "trick", simple re-declare declared and only
then place it into the scene, haha, exactly - why this has not come to my mind
automaticaly? :D Appriciate guys your help.

BTW some other question: how can I access some array values? I mean vector
values like ldd_camera_position variable consists of 3 values of x, y and z. Now
how can I access them individually? I come from FLASH ActioScript2 scene and
there you would do it easily like "ldd_camera_position[x]" where "x" is the
index number beginning with 0...so how it is made in PovRay, please?
