Hello everybody!

Can anyone recommend a good collection of low poly trees? Preferably a mix of common europen trees. 
Those trees should be used for a distance of over a few hundred meters (on mountains most of the time) and still look decent.
"Maxtree Plant Models Vol 47 Low Poly" look good but ~50000 polys/ tree, seems way too much for my purpose.

I know it would be best to have a photo of the site at that point, but it's sometimes not possible to get one.

Thank you,
Tobias

Ah! I found a good example for what i'm after ;)

What kind of trees were used here?
If there is a good tutorial on how to handle such scenes, I would also really appreciate any help!

Thank you!

Wont make a difference if you are using instances and/or scatter.

For example ive attached 1 tree from maxtree, 128k polygons. 14gb ram

Second example 240 instances of that tree, 14gb ram.

Third example, 40,000 instances. 16gb ram (most likely due to light calculations - which would accumulate with low poly anyway)

Thanks for your effort!

The problem isn't ram nor render time in my case, but the parsing time.
I have 4000 instances (7 different proxies) scattered with forest pack, and it takes 20s to start the rendering.
I now tested the same scene with an override material, and it starts in ~2s.

So you are right. It's not the geometry, but the material.

Are there any no goes for materials in such scenes?
Here is my Material btw:

Gosh i'm dumb!!

I checked all the materials again, and found out, that I forgot to delete the displacement map from 2 of the tree trunks.
No wonder it too so long.

Case closed.
Sorry.
