Tree from SU

Low poly and it renders great without any editing in Kerkythea

How long did it take to do?

You can create highpoly tree as well

tree design time - depends on you

export/import/export/import time cca 5min

Hi Starling!
Your workflow is much easier than mine! happy to hear this! And the result is less heavy too.
I guess I'm going to change mine with yours
I'm downloading meshlab now: importing as obj and exporting as 3ds, you say.
Gonna give it a go, definitely!
Thank you so much for such an important information!

I hope many SU users will start doing good trees and share them in the warehouse.

Actually I tried it yesterday after reading your post and it was my first attempt to "make" tree ..
Treed obj exporter created obj + mtl files but didn't add the texture files. I had to copy them manually from treed texture folder...

Meshlab is still beta, there could be some issues too.
The 3ds exporter seems to be limited up to cca 65000 vertices ...)

Leave message how it works for you.

That is exactly what i was about to report. But it doesn't seem to be a software bug, but a 3ds format limitation. I usually export 3dsMax models to sketchy and I remember that sometimes I couldn't, due to geometry weight (number of polys).
This single drawback is something making your workflow faulty: you cannot export ALL the trees you make.
If one wants just a simple tree, then your workflow is good.

I can export ALL the trees I make using collada format. There is only one small problem now, SU imports plain geometry without textures..

Don't know whether it's Meshlab, Sketchup or somewhere between them issue ...

%(#FF0040)[Well BS Contact trial shows tree exported from Meshlab via collada format perfectly. Conclusion is - SU should do better ]

There must be some kind of hidden option or something
Let's find it out: the first one who does, gives the other a call.

Thanks.
Let's wait for an answer.

I figured out why treed wasnt running on my system. You cant run it at 2560x1600 resolution, so I will let the developers know.

I always use a very simple skethcup tree. Found it in a model a few years ago.
It keeps your model small. I've tried it with complex trees but my computer crashes all the time.
Rendering in kerkythea with clip mapping of bitmap with leaves gives good results for me.
But i'm still searching for improvements. It still is not very realistic. Haven't tried to replace my tree with the tree of this topic yet.

OK I probably found possible way around ...

Make your highpoly tree in treed and export it via obj format.
Import the obj file using this TIGs script - http://forums.sketchucation.com/viewtopic.php?f=323&t=20584
Be patient

Et voilá

zipped highpoly tree

Hmm mine always imports into sketchup without textures. Workflow is:
Make tree in treed
export to OBJ format
import using TIGS script.

Doing anything wrong? Unless treed is not exporting the textures?

edit seems that you have to export the obj to same location as the texture maps. But half the leaves import as solid faces and half are pngs. Weird.

Yes - 1 face textured/1 face solid but render is ok ..

cadmunkey

Sorry I meant half render as solids half render with clipmapped leafs. If I reverse the faces of the solids then the mapping is all wrong. Maybe something I have to change in my render software, I'll check it out.

TIG

Read the MTL file [it's text and will open in Notepadetc] - this shows where the images should be found... if there's no folder in the image path [e.g. it's just abc.jpg] then they should be in the same folder as the OBJ, otherwise if there's a folder [e.g. images/abc.jpg] ensure the images are in it [/images/] before importing the OBJ - or conversely edit the MTL to suit the images' location[s] ! Also check that the image files and the MTL use the same names [note how a 'space' >> '_' and other punctuation goes completely] if this would cause duplicates then they'll get a numerical suffix [e.g. abc-1-2.jpg and abc-12.jpg will become abc12.jpg and jpg121.jpg] - some exporters fall down on saving the image with the exact same name as the MTL...

Thanks for your reply TIG,the materials are importing correctly. I think its my render program that has the issue. It is not rendering the png clipmaps that are on sides facing the wrong way.

I have Twilight. What is your render engine?

cadmunkey

Vray.

Thank you Starling for your research!
Now we can start sharing nice 3D trees!
Or at least I hope so!
