Yes.
Ideally, light and dark material is added here and there to 'enhance' the pic.
When trying to do this for a larger region, i figured it'd be handy to know how to steal the shading from an entire area.

Did lowering the sun closer to the horizon help any with the shading?

Ah, ok, thats what youre asking ...

These renders are not Terragen renders, theyre done with the 3D function of 'Globalmapper', a DEM translation and interpolation tool. Sorry for not mentioning that....

I dont think that Terragen is very usefull (sadly) for this particular kind of thing (see my other comments about TG above), although of course it has dozens of other virtues (one of which is rendering sunlight and sky).

Ive been playing around with Vue for 3D shaded overlays, and a bunch of other geographical apps as well, but I guess I yet have to find the app best suited for this.
I guess you have an opinion of how you`d tackle this with Max ? ...

Globalmapper with its 'box style' represents the easy route of ignoring the foreground area where pixels would appear as 'hypertstreched', as well the 'horizon-problem' which occurs at lower angles.
No sunlight, no sky, no horizon, no foreground, but 'it works'.
Then again, with Globalmapper, although there is hillshading of DEMS, there is no shading of overlays, which makes 'shadowstealing' a very important detail.

Okay, that clears up a lot for me.

Not much more than what we talked about early on.

I do recall a plugin for Max called Dreamscape that would create an environment. Land, sea, atmosphere, sun based lighting, etc. I think I remember it having an option to use your own images to create the land mesh or it would randomize it. But, I'm not certain. I only got to play with a demo of it for a few days a long while ago.

Just did a Google search for a link and found this:
http://www.afterworks.com/DreamScape.asp?ID=6

As it turns out, you can edit DEM or Terragen images directly inside this thing. I may have to get this myself.

Hi doonee,

I have an Italian Keyboard and had a similar problem... To select luminosity directly from the Layers the combinations that work with my keyboard are:

Ctrl+Alt+1
Ctrl+Alt+2
Ctrl+Alt+3

In alternative, in the Control Panel>Regional and Language Options>Languages, I added a few languages to my keyboard settings and checked the option to show an additional language bar icon in my taskbar ... This way, whenever I open Photoshop, I change my keyboard language to English (USA) and work with that ... mind you, it took me a bit to remember where all the keys were exactly, but, now, it is automatic ...

hmm, that looks quite promissing indeed.

thanks racc

-EDIT-
i couldnt find examples for single drape-style overlays in their gallery ..

Great Flora, that works here too.
(Layers appear to have to be named Layer 1, Layer 2, etc. for it to work).

Yep, i know, i have done that on my laptop. I guess youre right, it doesnt hurt to do that on this machine (which is bought here) as well ....
(Altho sometimes all this alt+shift back and forth stuff drives me nuts...)

thank you for the great tips !!
ciao ciao

From what I read on the site, they have a special material type so you can have the material automatically change with slope/height. However, there's no law saying you have to use their material. You could let the plugin create the mesh for the landscape, then apply your own material to it.

If you assign UVW planer mapping coordinates to the mesh, and then use your own image in the diffuse map slot of a material, that image will be projected straight down onto the surface of the mesh.

yep, sure
what i tried to say was that the use of a single sat-image draped over the entire terrain isnt really the scope of apps like max, vue & Co. There, users go about texturing the terrain in more detailed ways, using max-UVW, distribution maps, vue-ecosystems etc. etc.
Using a single bmp fto texture the whole thing doesnt make use of all these features and gives very varying results, because thats not so much what they expect their users to do.
Thats why i was left curious whether they had an example somewhere using a terrain textured by a single big image. I guess i have to try myself to find out.

(not so very related to this shading-thread ...)
another river test, showing that these riverbeds still need some editing.
