Rain forest

[Ecuadorian]

I'm longing to visit the small towns in the middle of the Ecuadorian rain forest, but work has me stuck in the city. Rendering one will have to do for now. Believe it or not, in the zone where the first layer of clouds touch the western part of the Andes there are some parts of the road with 10x more fog than this image; you can barely see the car in front of you.

Boring details:
Idea for scene setup inspired by Kwistenbiebel's instancing/proxies experiments.
Tree model by canadium: http://sketchup.google.com/3dwarehouse/ ... revstart=0
Distribution of trees thanks to Didier Bur's Component Spray with Spray shape > vertices of faces.
Original image rendered with Twilight Render @1920x1080 in mode Easy 08 for 1h37m on a Core 2 Duo E6300 w/ 2GB ram
Fog added in GIMP from Twilight's depth map. I exported the Depth map with several gamma settings and later layered them in GIMP in Screen mode. I also added in GIMP some vignetting, rendered clouds and Gaussian Blur. No Bloom added so as not to upset Richard. Downscaled to 1280x720 for forum view.

The SketchUp view and the raw Twilight render, before GIMP.

very nice demonstration, Miguel!

Pretty cool looking result.

So if i understand correctly you use a proxy, spray it around and then when you render the proxy is replaced by a component?

Wodering out loud...how would this work with preset 8?

[Ecuadorian]

It's simpler than that.
First, I spray a very simple proxy, might be even just two lines made into a component.
I then double-click on the component to edit it, making sure to "Hide rest of model" and "Hide similar components".
Now, I open the high-poly tree in another SketchUp instance, select it and Ctrl+C to copy it
I return to the first instance where I was inside one of my components, and Ctrl+V to paste it.
I immediately move the high-poly geometry to a new layer hidden in all scenes created with Jim's "add hidden layer". If you haven't created any scene tabs yet you can skip Jim's script and just create a new layer and hide it.
Making sure the high-poly geometry is invisible and that I only see the proxies, I close the component, place my camera and render.
This trick is possible thanks to Twilight ignoring layer visibility inside components by default.
I used preset 08.

wow! cool trick!!! thnx for the explaination

I tried this the other day without the proxies. it was an absolute nightmare, talk about a sticky model. cheers for posting your process.

by the way....do you make the hidden tree a group or component? so do you have a group within a component or....... a component within a component?

[fymoro]

wow!!! thanks for that and nice render also...

[Ecuadorian]

They're all components, Oliver.

Cheers, worked great. Can't believe I never thought of this!!

Incredible how quick it rendered too. how much of the time was spent processing the model?
