oh no ! more experiments !

[drBouvierLeduc]

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!

[carbon]

oh yes! really amazing!

[walter]

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).

[Olis]

Beautiful test renders!

As Usual some really nice scenes from you Doc

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!

[Kram1032]

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

[CoolColJ]

very nice renders!

[matt]

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.

[OnoSendai]

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.

[matsta]

simply amazing. some awesome renders. keep it up!

[suvakas]

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

[Stur]

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

[BbB]

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.

[OnoSendai]

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.
