Good Leaf Material?

Anyone have a method for creating a good leaf material? One that has some translucency when backlit from sun?

I have all the texture images etc....just don't know what nodes to try for the translucency, back lit part. Thanks.

I'm probably doing something wrong...but I can't get absorption or scattering to work on single poly leafs....I guess it needs volume?

How can we create this illusion?

I think that you should try to mix two materials, one diffuse to have the "Transmission" parameter to get the translucency, and one glossy to get the glossy reflections.

How do you put two different textures on a single leaf? Top and bottom texture?

I use a mix material for complex vegetation calculation.
One diffuse mixed with a glossy material.
The diffuse has transmission in it. I change the mix weight more to diffuse if I want them to be more light transparent.

The diffuse and glossy can have a mixed texture itself. With two sided material (polygon side).
Also you can mix the color variation with a falloff in it to get different color variations per tree.

I use the 3dsmax plugin but I guess the maps are the same.

U don't have to use medium nodes or scattering, just use diffuse material and plug leaf color image note into diffuse and transmission to also get the back lighting. There is a procedural node called polygon side if you want to have different textures on leaf sides but I don't use this. Also you can mix this with a glossy material to get some reflections on them.

look that video...i show your there what you have to do if you need leafs including light transmission support...(for PT-Kernel)
you need for that not a double sided polygon...

I did a quick test on this too today and I used LWs own crumple node, added brownish tint to it and then connected that to the diffuse materials diffuse pin. Everything else pretty much as instructed on this topic. Crumple node adds nice variations to the leaves..
