Hi all ! Have done an image with those trees from Aron Kamolz that I posted in the file sharing section. They were converted from Blender files into TGO format and should be available in Aron's Artstation or Gumroad acount soon. There is a free sampler available, with updated better version available later this weekend. The work on this one was not very much on surfaces but object placement, light and atmo. This is a preliminary render with others to come. Thanks for any comments and suggestions ! Paul

This is looking really good! The veggies are well chosen, and the light and haze are great. Looking forward to your next versions.....

You could try some veggies on the water, like lily pads near shore, a bit of murky algae on the surface, or small rushes, or patches of reed/grass. But that really depends on the type of river you intended.

Absolutely beautiful! Along with Ulco's suggestions I'd say, that the shoreline looks very dry. Mabe a bit darker and some specularity would be good. And I guess, it's rendered with the legacy renderer? If so, try the path tracer. Plants in indirect light always look better with the path tracer. If it IS a path tracer render, I'd activate or increase the GISD.

I just answered you in your other thread, and came back here to take another look at your image. Did you use a cloud layer for the mist? If so, did you check "Receive shadows from surfaces" in the quality tab? If not it might be worth a try as well, to get some more depth in the forest.

Hi Hannes ! I did use a faint cumulus layer for the mist ! I did not check the receive shadows from surface...... so another spot to adjust ! Appreciated ! Paul

Nice render man! Love the lighting and mist. Veg and rock look pretty great too! 
The more I use Terragen, the more I realize the world is not so small.

Thanks guys for the comments ! I did another render with the sun in a different position and also inserted another sun opposite to the main sun, no shadows, no atmo effect but at 90 degree high up in the sky with a value that was approximately 5% of the main sun, to give the Path Tracer some light to play with ! Thought this might adjust for the lack of effect of GI with this render mode. It did render the shadows a bit better without giving too much light to make it look nuts ! Have also inserted a moon and some faint stars where the sky is getting darker from the setting sun. Have also done another of the same position as the first and will illustrate the various study renders to illustrate the differences ! Will post those later ! Thanks again and take care !

I have to say that the vegetation on the lower right side looks kind of weird. Most likely the lack of shadows. It's less obvious on the left side, but I'd say, I'm looking forward to your other tries.
Actually I'd love to see your image with just the default light settings (one sun, one environment light) and no postwork.

Dune

Agree with Hannes. It seems the sun is so low now, there are no shadows anymore. And an extra sun I would set at 90ยบ (straight up, at any rotation) and strength maybe 0.2-0.5 or so. That will only throw some light on the tops of branches and leaves (and ground), so also leaves some darks on steep sides and undersides.

Hi guys ! I thank you again for your help ! I am including on this post the trials done with the standard and path tracing renderers. The first image is the "Initial Render", path traced, one sun, GI 3.2 but later I note that this really does not impact the path traced render ! The left woods are extremely dark ! I then bring it into Photoshop and boost the shadows on a duplicate layer and then blend it into the first and come out with the "Initial Render Photoshoped". It does look pretty nice although still a bit dark. The problem is then that shadows function can really mess up some of the things that are right at the outset sometimes. I then redid the same image with the standard renderer with just one sun at the same spot, strength of 9 and GI a bit toned down at 2.9...... and the "Standard render GI" was the result ! Then a second sun was added at 90 degrees and a strength of 0.8, no shadows, just lighting surfaces and the result was "Path Traced 2 suns". This is exactly how it came out, no Photoshop involved ! I think the veggies look better with the Path Tracer but I might have done better, as Ulco said, to have the high sun even weaker, say around 0.3, again as suggested. This would have likely given me just the necessary lighting for the Path Tracer to give me details that a milder Shadow enhancement in Photoshop would have made nicer than my initial post. The next step is to do exactly that..... but have to change a few things as that last one, with the light coming from the left was done on my PC rather than my Mac and I love the additional trees that were inserted in the woods..... younger beech trees with more lush leaves ! I will fix this today and do another render overnight. I am having a lot of fun with these trials..... and thanks to you all, learning quite a bit ! Appreciated ! Have a great weekend ! Paul

Actually I like your "Initial render" most. But yes, it's quite dark in the forest. Maybe it's realistic, since a real camera might see it like that. Either the dark areas are brighter with an overexposed background or the way you rendered it.
But there's one thing that came into my mind: what, if you'd add the second sun straight up in the air, but with (very soft!!) shadows activated? For the path tracer you can decrease the samples for the soft shadows, since the path tracer handles it pretty well (I think Matt wrote something like this some time ago).
Nevertheless I'd love to see, how the hollow hemisphere solution would look in this case.

Dune

I again agree with Hannes (boring...). It may also be that some settings in veggies are better than other for certain light circumstances. Like translucency, reflection, opacity, leaf color base...

Hannes

OK, I created a scene somehow similar to yours. Here is the result.
As expected the original render is quite dark in the forest area.
The second sun/no shadows image rendered the fastest and looks terrible (to my taste). The second sun w. (soft) shadows image took the longest to render. The trees look quite nice, but the shadows on the floor don't fit to the "real sun".

For the other images I loaded the hemisphere that I already mentioned. I attached it here. It has a radius of 50 meters. You can scale it like desired. I think, the hemisphere only has to cover the foreground trees in your case.
Paul, you asked me how to make it invisible and so on. Here are the instructions: after you have imported it, go to the object's "Rendering" tab, uncheck "Cast shadows", and set "Render" to "invisible". No need to care about the normals.
I used a luminosity of 1, which is the value in the TGO. Do some tests in your scene, and use a value that looks best.

If you use this method, you may have to increase the AA. The indirect lighting tends to render a bit more noisy.

I hope, this helps. Actually it was great fun to make this comparison.
