Cool (WIP) Post Judicium

This is called Post Judicium. Think of it as a post-flood scene. This is my first full render in Terragen 2, and it was color-tweaked in Photoshop CS5.1. Once I've perfected the scene to my liking, I plan on either a 1920x1080 or 3840x2160 resolution render.



This 880x495 pixel render took almost an hour shy of 24 to complete on 5 of 6 cores on an AMD Phenom II X6.

A newer render is underway with rougher seas, as this sort of cloud cover would imply wind-flow, which is inconsistent with a calm surface on a body of water.

I'm open to critiques!

bump, due to moderation box time allowing this to go to pg 2 before visibility...

Looking good. But keep note of the waters.
They look kind of flat due to the lack of depth.

Maybe you can create in a more active behaviour ?

Here's my 1920x1080 render so far with rougher seas. I think this may be pushed as high as 250 hours at this rate.

Yes I was a "dumb ass" and turned everything on and up. I want to see what Terragen 2 is capable of with everything on Godlike.

Here you go, enjoy!

These examples aren't really encouraging for others to try Terragen 2 as this gives the impression that it is mind-boggling slow, which it isn't
I'd pass it on to the Terragen forums and find advice to render this in ~2 hours, which should be feasible if you'd ask me.

Nonetheless the sky and lighting looks painterly and very nice. I don't have problems with depth of the water. It's just accurate.

This render is a test with everything on 'Godlike.' Terragen isn't so slow if raytrace everything is off, detail is kept less than 1 (~.8-.95), and GI is kept at 2 instead of 3.

Realize, this is a 1920x1080 render, but reduced by Terragen 2 in that preview to fit that window. The detail isn't accurate and won't be until it completes.

(God willing, one brown out could kill this progress. I really need to get a UPS since this is rendering on a VM running WinServ2K8R2).

I need 64 cores

170 hours is way over the top, something must be amiss.

A few suggestions:
Firstly I'm assuming you have a decent computer.

Renderer:
Detail of 1 (or higher) is almost never needed andthen only really when incorporating high resolution models. Similarly an anti aliasing of 8 is extreme, for a soft scene like this I would probably not go above 7 for AA.
I assume your using GI lighting in which case the default values (2,2,8) should be fine. There is little sub-pixel detail in your scene so GI surface details can be left un-ticked.

Lighting:
Also regarding lighting I really hope your NOT using soft shadows, it will have no effect in this scene other than taking up a lot of render time.

Atmosphere:
Make sure Ray Trace Atmosphere is ticked in the render tab. The sample level of your atmosphere needstobe set toa value that removes the noise in your light rays. At a guess something about 48 should work, possibly less, possibly more, but with Ray Trace Atmosphere ticked it should not be in the hundreds.
You will NOT need "Receive shadows from surfaces" ticked. Again this will have no affect in your scene since there are no surfaces above the clouds to cast shadows onto them. It will add considerably to your render time.
Regarding clouds and atmosphere take a look at your sample levels. This is down to trial and error and experience.I tend to go for something like 0.8 detail per 500m thickness of cloud and take a look at the sampling this produces. Go for something that is enough to remove any noise in the cloud and no more.

Water:
Not much to say about water except that if you have a cloud layer that intersects the water your in a world of hurt. Think of the problems the raytracer is going to have going through volumetric clouds,through a refractive surface and then doing it all again, a definite render hog, try to avoid it. Also looking at your preview the sea looks unnaturally choppy. Do a lower resolution cloudless version to check it is how you want. Too finely displaced water is also a render hog.

Hope the above helps and my apologies if advice was not wanted.

Cheers

Richard

everything is on and up, GI is 3 3 16, AA is 8, Detail is 1, there are soft shadows, everything is raytraced, and everything casts shadows. If there's a detail not on max, it's because I missed it

Still rendering, at almost 190 hours render time.

This better be the best damn fake sea-sky-scape image I've ever seen at HD!

So I suppose you're completely ignoring Richards recommendations, which as a matter of fact are spot on?

You're wasting your time, really.
