Thank you both it works of course.

I would really like to learn more about using HDRI light maps to light my
scenes and objects.  Can i do that with the current version of POV?  I have
seen online Mega POV and i have downloaded it.  but does it just run in the
background to the main POV 3.6 windows console?  I am a beginner with hdri
for sure so some comprehensive tutoials would be wonderful.


Thanks again!
