Quote - I also noticed that the Tree props that I have downloaded from somewhere is actualy a photograph of a tree posted on a transparent background or ..... posted on a transparent flat background polygon.

Those "tree props" are poster boards, not really tree props.  I don't know why people upload them as "tree props" because that is not what they are.

RDNA and Daz have tons of real foliage props that are actually props and not "trees on a background image."  Plus you can find some free ones around the poser sites too.  Planit3D has some free trees and plants.

If you need links to other free sites, let me know. Either me or someone else will be able to post more links for you.

"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
