Vegetation test + several more questions

Well, this is interesting. It looks like those trees, or my old materials had a huge impact on the scene. I just tested IBL to fix the grass, but, it doesn’t need fixing :smiley:



Nice improvement. I usually use darker color in bark material to give the tree some contrast.

Looking at your renders it seems like i made the anatomy of the tree really bad, the end branches are to tin. If i get some time this week i´ll fix it.

Can I animate trees created by GrowFX?

Thanks, i didn’t touch the bark material, i focused on greenery in this test :smiley: Which i will fix, ofcourse.

From their site:

You can animate almost all parameters and create any plant animation: growth, wind, etc. It’s also possible to use the Affects mechanism to get specific parameters to influence others, so that you do not have to configure animation by hand. For example, you can set up a dependency of the length of main branches from the overall height of a tree, and dependency of small flowers from the length of main branches. Then it’ll be enough to animate a tree height to create a fully-fledged animation of a growing plant.

Thanks for reply. I forgot to mention that my idea was for the tree to be affected by the wind.

Do you still the Walnut tree model?

I’m not sure what you’re asking :smiley: But this personal project of mine is, once again, back on the waiting list, so no wallnuts for me right now :smiley:

I mean the tree that Adanmq created. The link is dead. Do you have it by any chance? I am asking because I start working again on a personal project :tongue:

Hi.

Let me upload 2 better ones, the walnut have bad anatomy. This ones are originally big birch trees. 20-25m (you may need to scale down). Keep in mind that these trees are made to mid/far distance and very specific project (may not work for all circumstances), they need more details for close-ups.

Hope you can use it.

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.

Quick test with Laubwerk models; IBL.



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 Speedtest by Ookla - The Global Broadband Speed Test :smiley:
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 :smiley:



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 :smiley: 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…
