Hi Tar!
As you told you are using SketchUp, I'm more interested in the technique you used to create your ivy.

Can you please share the method? It's quite an interesting result for a sketchup model!

Yes, I was wondering this too - I'm messing around with the Fur plugin and an ivy texture but I can't it to look right....

Tar, if you're happy to share that would be great. Thanks for uploading the grass material too, works like a charm

Ignore the displacement glitches in the wall though....

Fantastic results, Bosseye!

And thank you very much for sharing, tar_gniK!

If you are referring to the foliage on the wall, this was done in a similar manner to the grass.

The difference with this is that plane on which I applied the texture was folded, bent and curved in a way which depicted something close to reality.

In addition, more than one plane was used. I combined one plane with the texture, with another. The second plane was rotated and skewed - making sure that the branches meet each other. As before, you create a component with the two planes combined.

In terms of using the Fur plugin, it was a bit of a lottery, because you need to rotate the planes WITHIN the component itself, because the Fur plugin reacts differently depending on the orientation of the axis within the component.

To apply it to the wall, again, I created a ridged surface, and to achieve a natural surface, I used the Randomize TIN plugin to create more organic plane in which to apply the component. This was smoothed, as before. I like it more with the gaps, rather than the whole plane to be filled with plantation.

Hei Boss, it's a great plane what you have under your grass, is it displaced?

Thank you for the tut, tar!

Its just the 'stony ground' texture from the Indigo Material database - I've done nothing to it, so whoever made it gets all the credit!

And yes, thanks to Tar - very useful stuff. You what I'm going to say now, any chance of posting the leaf material you have?

I've uploaded the material to the database.

I'm still wondering however, if SSS can be applied to materials of this nature.

Sorry, completely ignored your question earlier - I'm afraid I don't know on that one. Someone will though, guaranteed. If its a burning issue, you could always make a fresh thread about it.

Thanks for tutorial on leaves etc - works well enough for me I'm forever in your debt for telling me about the fur plugin..

[Headroom]

I don't think SSS would work in these cases. The specular materials in Indigo are based on light traveling through a medium (as opposed to being reflected by an infinitely thin surface) so your geometry needs to define a volume for that medium.

Your grass and ivy look pretty stunning already without SSS!

[PureSpider]

You can always just use diffuse transmitter for "single layer SSS"
Be sure to have no volume then, however, only simple planes!
If you want it more opaque you can clend it with diffuse/phong.

[ENSLAVER]

Here's one that is blended with a diffuse transmitter (89% diffuse transmitter) - Might be a little much for everyday grass but it depends on the scene. I find it works ok.

First blend is for opacity, last is between phong and diffuse transmitter (fast sss) - the phong is useful for adding some reflection to the grass - roughness/smoothness is @ 35 (1.5 ior ), probably tweaked depending on the look you want - ie. wet grass

[tar_gniK]

Thanks Enslaver, looks really great.

Could you provide however, a step-by-step instruction on how to set a material like this up? Looking at the material in the editor, there seems to be a lot going on!
