Thanks y'all!

Attached is another,hopefully improved,version.
Planetside: as for the first version the Reflective Shader refused to give
me specular highlights no matter what,so i had to delete it (which gave
another ray trace error warning btw

) and to replace it with a new one
and that is working again.Odd.---Please let me know,in case you want to
examine this.
arisdemos:probably not the tgd,but a tgc with the appropriate nodes,if that
is ok for you.
