Vegetation test + several more questions

[CiroC]

Adanmq thank you very much.

The reason why also ask for the tree is because I am trying to see how you created the leaf material.
I use refraction and transparency, but I am not too happy with the result.

Nice work Blank. I have been following this post for a while and the result is very interesting. Do you want to share you scene? I think it will be very helpfull for a lot of users!

thanks.

I want to, but i'm afraid i can't. And this is why http://www.speedtest.net/my-result/3772789968 :D
After i added Laubwerks models this scene grew to one gig, it would just take to long to upload. Even if i deleted scattered geometry, three of those models are still over 500 MB. What i can do is make one huge everything screenshotted image if you want. Everything used in this scene is available on the web, should be easy to set up a similar test scene.

Here are some more tests with new energy conversion mode and GGX, i just changed those two, some tweaking of materials will be needed :)

Adanmq, thank you for those quality trees!
Good trees need good textures, so there's my contribution :]

Thank you both!

No problem Blank. I was curious what changes you made to your posted material setup (few posts ago) and the laubwerk renders.

Thanks guys for sharing quality!

Here it is, since leaves needed less reflectivity i did the first logical thing - increased reflectivity :D But i played with IOR and glossiness map output, nothing fancy.

Hi guys! I have a big problem ... my head already broke))) I can not make shader grass. Looked a lot of tutorials about this, but ...
Grass looks unrealistic(((
1) bitmap rather dark, but render the grass looks very bright
2) glossy lowered to 0.35, Reflect up to 35, but in the long term glossy still very strong
I use in this scene corona sun + sky
I attach below a few shots of my scene.
I want that looked something like the last two pictures

advise how to fix shader, thank you.

In the reference pictures you posted the grass is in shadow, this may be the problem. For such objects geometry and lighting also has huge impact on appearance so maybe you should experiment with these.

Yeah...i understand it, but in my scene sun position should be low and this factor take me bad result of shader grass.
P.S. Sorry for my english...
