As every thread seems to be dealing with tests lately, I give it a go.
I'm not testing indigo's latest kick ass features, but rather playing with shaders and indigo's infinite possibilities in that domain.
So I'm not heading anywhere in particular, just a bit of fun (and learning) with blended materials, sss, exponent maps etc...
Hopefully all this will made some proper scene in the end.
So here are a small bunch of images.
Just a note on the leaves : I used the same technique as explained
here (at the bottom).
I got something, but if think the sss values can be improved (or is it the model who need some tweaking ?... dunno. If I had more vertices to the model (150k !), I think my computer will explode).

damn, you got a "chlorophyll" mat!

Beautiful!
Is that a mate I see in the first pic ?!
test-balls3.jpg looks especially nice. I like the effect you created with the blends...
Regarding test-bamboo2.jpg .. I'm not sure I've ever actually been able to see through a leaf like that :P but its probably hard to get that balanced with the right SSS (which looks great, btw).

As Usual some really nice scenes from you Doc
drBouvierLeduc wrote:the same leaf viewed from bottom. Hurray ! When lite from behind, you can see the leaf's translucency. I Made billions of tries before I got correct translucency. (although it looks a bit too much like gelatin)
You have to give your mesh some volume, otherwise there is no scattering inside the leaf, because there is no "inside" ^^
Otherwise you could try using a glossy Transparent Material, instead of specular this should enhance the result drastically!

in that case, it would be black, anyway, wouldn't it?
Although....
Argh... Not shure, anymore, about that.

Can you give us the specifics on the SSS settings for the leaves and a general idea of how thick you made them? It's looking good. Wouldn't it be faster to get that effect with a diffuse transmitter and a single sided leaf? I thought that was one of the things diffuse transmitters were made for.

Stunning materials as per usual Dr.
Can you go into a little more detail on the leaf material?
It uses a diffuse transmitter / phong blend, right?
Would you consider writing a tutorial on the leaf material, or even just post the material to the forums. A high quality leaf material (or guide on how to make one) is something Indigo users need.

Very, very good tests !!
I specially like the sun + plant composition.
Leaf material is also great too.

As usual, your tests look like finished masterpieces, it's so frustrating for common mortals like us ... But please, send more !
Now that you prooved you are the materials master here, you HAVE to post some tutorials

Docteur, you send my jaw dropping every time.
One small footnote, thought, I second other comments about it being actually unlikely that you could see through a bamboo leaf. I would also try a diffuse transmitte instead of SSS. It may or may not look better, but at the very least it will clear considerably faster. Anyway, just my two cents as a noob.

Yeah, you can't usually see through leaves like that.
To put it another way, any light that makes it through the leaf will be scattered at least once.
