Alain,
thank you so much! I will definitely fix that. It's been a long time since I
worked with triangles in POV...
I have a new problem ..haha. Now that I've converted these billboards to smooth
triangles, I'm getting a new fog bug showing up in reflections. I'm posting a
snippet of a rendering I did last night using these plants in my nest scene.
Billboards that cross in front the water renders without fog. Strange...may just
give up on using them in this scene. :-)
Mike
