Wow Rusty that looks amazing!! I agree with Mike that the DOF gives that minature feel, though as you suggest an aim in question. Looks darn good to me!! Great mapping!

What size mate do you normally render these at?

Here is my first test with thin SSS haven't quite got it working for me, and tried something different with the grass and yep that's not really working either!

Richard, are you using sss for both the grass (lawn) and taller grasses? Just very curious as grass on non-planar surfaces is next...what 3d app are you using? Is the grass all geometry (if so, that is a LOT of geometry). I would very much appreciate knowing your workflow. Joe

Those plants look nice! maybe a bit bright green on my screen though.

Joe, SSS just for the tall grasses. The lawn is simple two plane grass! All modelled in SketchUp, four grass blades per curved plane. I've tilted the planes so that the blades dont end up horizontal and disappearing at low camera angles which has seemingly worked well!

@ Burnum

Thanks mate, thats the bit I haven't got my head around with the sss, change the saturation of the maps just a spiders dick and half the blades go grey really fast!

I can't workout why when looking at the top of the blades the light is coming through but when you see through from the underside they are dark with no sss! Anyone? Brian?

[Burnum]

Oh wow, I didn't notice the dark part, I can see the darkness in there. Odd.
I haven't started to experiment with thin SSS much yet...

Yeah I'm sure it can be controlled, Bubba's tests show differently! If it can be controlled the nice thing would be that keeping a bit of it could be useful is setting a non homogenious feel to leaf clusters. Often differing top and underside roughness on real leaves gives that effect to some degree in nature!

richard, the tutorial on the think site is a really good one for grounding your head around the single sided sss equation.

there's a lot of strings that affect the sssss mats, but from what i've experienced, adjusting the saturation of your transmittance map (if i remember correctly) can give you greater control over the saturation of the material itself. oh, and thanks for the kind words. the image of the cattle originally rendered out at 1600? (i can't remember exactly), just as clean as the downsize for web with displacement on every material except the grass

I looked at your tests you did, and I noticed that in all of them you have used a single layer with 2 bsdf. Try using multiple layers, and separate the sss and the texture into different layers and weight them. Also, be careful with the roughness setting on the thinsss layer. Keep it low.

With the new stacked layers system, you need to start thinking differently about material creation. For my leaves, I started with a base layer for color/texture with high roughness. Add an additional layer for each new "effect" you want to add.

very nice summer ending... cool atmosphere.. perfect materials..

Hi Bubba,
well your leaves are a lot better than mine on my evermotion trees. I got the sss leaf thing now ok and understand a lot better how it should be done.
You are right about the layers, its best to seperate things to finetune materials instead of trying to tune all settings at once. That got me stuck for a while. Too many conflicting settings in one bsdf.

Would you mind sharing your leaf mxm for us to see how your settings work out along with your fine image ?

[Bubbaloo]

I'll post some leaf materials soon.

[numerobis]

WOW! great leaves Bubba!

[Burnum]

Wow! very nice!

These are not leaves, they are great mxms attached to a tree.
