Majid,
There is a ruby script to export your SketchUp Model to Luxrender and the
name is SU2LUX (SketchUp Exporter).
http://www.luxrender.net/forum/viewforum.php?f=35

I use that method and another from SU to blender with script called:
lwo_export.rb

One helps the other.

Here is another render and also grainy because of low render time.
This one was done also with Luxrender months ago.

Nice work, looks good.

Looks very nice.

Dermotcoll,
Render is grainy because I did a 15 minute test render on an old laptop.
Im trying to get my materials settings. The white is a plastic material.
I want to get materials ready before i render scenes with more objects.
Grass looks to saturated.

Update...

Trying out Luxrender. Sky and concrete from Google ware house.

This site might already be listed, dont know.

Michalis,
The files are exported as obj files from ngPlant and imported into
blender as an obj file.

Here's the link to the tree file:

Here is a one blender tree and its a 23.5 mb file.
Hawthorn Leaf is not included because i couldn't redistribute from this site:

Image below and the tree is the one in the middle.

Majid,

Some were imported directly in to KT and the ones from Google were exported
with SketchUp.

I have Encyclopedias of tree settings.
Maybe if you send me a site were i can send my most recent big tree.

Very nice work. Excellent work on the second one.

Thanks Majid.

D-space,
What is Post-pro?
I have problems understanding some of the words used here.
The big trees are 3d trees made with ngPlant.
Some of the smaller ones are blenders from:
http://blender-archi.tuxfamily.org/Greenhouse

and the other one's from the Google warehouse.

Kt Renders.

Nice render. Have to study this one.

Some changes. I changed the first tile on the ridge and made it bull nose.

I change the material to plastic for the tiles.

Here the building is rotated to a 45 degree and walls bumped up.

Majid,

Blender, As a renderer does its job. Blender as a modeler, I think
its very hard and i rather use SketchUp for modeling.
The grass in the render is the only model that is Blenders and it does
an excellent job in making grass.

Here is a 4 1/2 minute laptop render with blender. Im testing different roof
tiles. I need another, I dont like this one.
