Good Looking Leaves

[AnconeusRex]

I'm not sure if someone has asked this before, but is there a way to make leaves look good from underneath? By that I mean, does anyone know of a good way to get this subsurface scattering look? (For some reason the attached link isnt working, so here's the original: http://farm4.static.flickr.com/3659/...61cfd96fd7.jpg)

Use FstormFrontBack and a translucency map. If you don't know how 2sided material shaders are generally created I encourage you to watch a tutorial video from other render engines since the main steps are the same.

Hi deC9r,

I'm attempting to set up a proper leaf material
Could you elaborate on the use of Translucency node? Translucency in fstorm seems to work in an unconvential way, here is the problem:

I set a FrontBack material; both the front and the back material have a 'grey' mapped in their Refraction (test A), and Translucency (test B).

Why does the Translucency comes out blurry?? From the fstorm manual: "translucence works like a refraction with zero glossy"
Should both test come out approximately similar?

Thanks

Could be wrong.

Karba can you add your 2 cents for clarification?

I would use 5 times less nodes.

[deC9r]

Fair point, however I was testing therefore performance doesn't really concern me at this step. I noted that opacity map didn't work correctly on planes which got bended by a bend modifier, It rendered as if the modifier didn't exist (noticed because reflection map was cut off). I did not convert to an editpoly. Could also be an UVW issue. Did not investigate further.

Cleaned up.




Added proper reflection, tuned a few settings:





Rendertime about 2 mins. It took 800 samples to be noise free (99,9%). Nativ resolution 2k/2k.

Try this settings

Wow, those look great! Thanks!
Out of curiosity, would more nodes decrease the performance noticeably?

[deC9r]

You loose quite a lot of details. However the effect looks really good. Btw I think the reflection on the translucency version is currently the problem. Render times are pretty much the same.

added a translucency version without reflection.

Hi Karba, I would like to know this too. Useful for future scene optimization. Thank you for taking the time to help on these small matters.
Thanks to deC9r as well, I agree with you, translucency seems to preserve better details, especially with a proper bitmaps.
This thread helped me alot to understand Fstorm's material setup.

Here is my attempt at foliage. Still need tweakings, will post a complete final scene once I'm satisfied/

Because I used printscreened textures from your post. They are low res.
