the leaves at the bottom of the image - you are viewing the top side of the leaf. To display the comparisions I have made a basic scene that has a physical camera, a series of flat planes with a similar leaf shader applied and a vray sun/sky backlighting the leaves (to get the nice translucency effect we all know and love). The problem is that this shader looks absolutely terrible when rendered in RT. For those who are not familiar - here is the shader tree. It works pretty well and is pretty realistic. Its that Bertrand Benoit 2 sided material that seems to now be the standard. To start with I have the leaf shader that pretty much everyone seems to be using since this forum thread. I'm not sure to what extent the 2 sided material is supported with RT but from the tests I have done it seems that it doesn't really work at all for vegetation. I am trying to make a realistic looking tree/plant leaf material that works in RT.
