I got a PM from someone that told me that you cannot use 3D Studio Max files in Poser. I did it earlier today and it worked. I downloaded a plant file from Planit3D that was in .3ds format. I imported it into Poser and saved it as a prop file. I made several renders of it too. Here is a screenshot of my Poser and shows you what to pick in order to import .3ds files into Poser.

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
