Forest Glen *Final Version April 2nd*
« on: March 24, 2008, 02:01:04 PM »
I've been trying to do a decent forest render for awhile with little success.  But finally after reading Matt's suggestion to up the exposure in a post a little while ago I gave it another shot with much better results.

Took around 75 hours at 0.8 detail 16 AA 2/2 GI.

All objects downloaded from Ashunder:

Trees and Bushes were from Lightning
Flowers were from Bobbystahr
Grasses were from Sonshine777

Thanks for taking a look.

I like the lighting.  It's very nice.  What I wish to see, but will probably need to wait for the next release, would be a translucency to the leaves.  That would be very cool.
So this is Disney World.  Can we live here?

Good work on the lighting, but the trees are not realistic, it's damage !

agree with Phylloxera, very nice light but it's too bad for the trunk of the tree...

The version we are using can do translucency, itís one of the settings in the Default Shader.

they look like my acer sac trees its when i had troublr converting my models for terragen i will reup a better bump which should do the trick i think

anyway amazing lighting looks awesum ae
well done indeed!

Thanks for the comments.  I whole-heartedly agree about the geometric leaves, but not being a tree modeller myself, I use whatever the kind people of the community donate  :)

Lightning:  If you would be able to upload a new version of the Acer Platanoides with a real leaf shape and texture I would definitely love to re-render this with some luminosity.

I think it's a remarkably nice image even with the problems others mentioned. The lighting and atmosphere alone really "sell" it. If you fix the minor plant model and translucency problems it would be stunning. Despite the long render time, I really hope you'll re-render with those improvements. I'd love to see it!

I believe I have the leaf issues sorted out.  I did not know that I could just take a real leaf, photograph it in my lightbox, and create my own leaf textures for any posted tree.  :-[ For some reason I assumed that it was all handled in the program the tree was modeled in. Running a few test renders now to try and get the right amount of translucence, and then I will do a full re-render.  Anyone have a guide range of translucence values that turns out fairly realistic?

Unfortunately I don't really have it, because it's quite different between scenes.
I'd try for small crop renders at high detail and middle-resolution to experiment with it. I'd go for translucency values from 0.75 - 2. But there are quite some leaves so maybe even higher values are required. Hard to tell.

You can also replace the bark-texture by one of your own.
You can go to http://www.cgtextures.com and you'll find some very nice high-res barktextures. In photoshop you can create nice bumpimages.
Be sure to save the alternative texture in the same aspect ratio as the original one so it will match the model.

If you want I can help you with making the texturesize and resolution right and also with the bumpmap.
I have some test-renders using these bumps and I can show them here if you're interested.

i have re textured my tree it looks much better this tree was one of my first trees i converted to terragen 2 so it pretty crap have
take a look at this thread where i am doing bark texture tests
http://forums.planetside.co.uk/index.php?topic=3693.0
this is the acer tree you are using just with a lot beter textures i will re-up this and u can use it in your re render!

little update after 40 hours here is the top portion (captured with a print screen).

It is looking far far better than the previous render, hopefully the rest looks as good when finished in another 60 hours or so (baring any crashes). I created a new texture/leaf/opacity image and bumped the translucency up to 2 for all the leaves.

Martin:  Thanks for posting those images in the other thread, they look very good.  I will have to do some more experiments with the bark for a future project.

Further updates to come when finished.

This is looking pretty good so far but I'm thinking if this area took 40 hours and I'm assuming this is the full size?  It looks like maybe a 1/3 of the image, right? That means the remaining 2/3's will take approximately 80 more hours (5 days for the entire image, IF it doesn't crash?)

Don't get me wrong, if you enjoy what you are doing then by all means, enjoy. However when and if it finishes rendering and you want to print it for preservation sake what size print could you get from it? I think a 5x7 is about it? 5 days for a 5x7 print to me just isn't practical.

I'm not trying to Burst your Bubble I'm just trying to look at in a realistic and practical way.

Nothing against you or your work, like I said it's looking good. My point is about TG for my personal use. Even if I see a 10% increase in render speed when the final comes out TG is still pretty much useless to me. It's sad because I do enjoy and have been working with TG, the Old and the New for quite some time (roughly 8 years).

Have fun and good luck

I like the translucency you're getting.  I'm encouraged that it will be even better in the next version.
