Hi friends,

some things I found out & like to share when wondering about translucency on single sided leaves.

-Instead of using a Diffuse + greenish RGB Spectrum for transmission, you can also create something similiar looking by creating a Specular material:
Set its reflectance to "0", its index (refraction) to "1" and increase its roughness value.
Now plug your leaf texture to the transmission port, done.

This also looks good when used in a 50/50 mix with your old diffuse material.
even better: Use Photoshop to create some additional textures: bump, transmission, opacity.
Will boost realism a lot, even on low-res leaf geometry.

All test renders were lit by a huge emitter with a strength of 23.000 and no extra environment light.
pathtracing.

great man!! Thats very very usefull.. I think Ill try the third material in the first pic. for the wax material

NICE! and Thank You.

If it is possible can you post the ocs, obj, mlt and the textures, if it is alright with you i can add this to the octane tutorial series

this looks really nice, maybe you could post it in the resources forum too ?

Wow complex shader tree setup. Must take a lot of resources to compute. But the result is very good. WOuld like to see a render with a backlight sun on a tree.

this looks very, very nice! thanks for sharing your ideas.
ps: i'm also keen about the rendertimes for the images you posted...

This is great, i will try it in my low poly trees. Thank you for sharing.

Thanks guys.

@radiant: I´m sorry, I can´t provide the ocs & obj as this is the leaf is a commercial model from evermotion.
@t_3: rendertimes laid between 20 and 60 mins for a 2K resolution, pathtracing with a raydepth of 64.

Oh, could an admin move this thread to the resources forum?

Hey , I can get You some tree model... which I could allow You to share

I will set it up with an Ivy model. Will check back later. Need to get myself a beer and start then.
