Why do these trees look real?

Generally speaking, the leaves on trees are pretty much all the same colour, it is the angle they are at which alters the light hitting them and the shadows from other leaves which makes them appear different colours. Well-lit ones will appear more yellow, ones in shadow will be dark green. You have to simulate that on a 3D model with the texture if a 3D engine cannot individually light things, which it probably isn't going to get the chance to do even if it had such on the fly capability, unless a tree has been modeled 100 percent accurately, which would require millions of polygons, since you'd have to model each leaf LOL.

He's obviously not using native mode and they look like Trundra's G:Trees to me, believe me with the exception of one fir tree which has more than two billboards they won't work in TS12 I've tried every trick in the book.
Actually I had a go at some bushes pinching the idea from the Treez add-on, these were quick and dirty maybe you could improve on the principle?
Hi Ed,
I will be looking forward to your new trees, hopefully they will resemble something more realistic than the speedtrees.
I have noticed the trees in the top picture of Boleyd post above, as being near on perfect, but I am sure if you turn your camera around on them, they seem to flicker a little, as they are fighting with the other same trees around them, that is the only downside, Trunda trees are really good, I am not a fan of the flickering with other similar trees on the same route.
Now with the Speedtrees, these are also very good, but as you go near and far with them in winter time, the twigs seem to vanish then re-appear as you get nearer, and in the summer, the trees seem like twigs, with green bits hanging of them, and they seem irregular and not rounded, like something has attacked them, and of a night they sometimes seem to twinkle as they move, and some actually glow in the dark as they reflect the sun what is under the baseboard, this happens with the plant speedtree. I am not much of a fan of the Speedtree, but I make do with them for now, if something a lot better came along, I would most certainly use them.
Now most trees I have seen have got the trunk in dark brown under a shade, with the leaves on the trees giving off an overall rounded look, and mostly bright green on sunny days, and a darker green on cloudy days...
SUNNY DAY - Leaves are bright green, patches of bright yellow and green from the top and fade under the shadow to a darker green under the tree, you can see the darker equivalents in the background.
CLOUDY DAY - leaves are darker at the bottom of the tree and brighter green as you get near to the top with little bits of bright yellow in places around the top of the tree.
The above are two examples of real trees.
Now if you can get the trees to look similar to what is on this site... http://forums.uktrainsim.com/viewtopic.php?f=302&t=95401&start=300, and by the way, I don't care if they move or not, or even if they have shadows or not, as long as they look better than Speedtrees, then I will be happy...
Hope the above helps Euphod.

The example of the brightly lighted yellow tree and the nicer looking one under reduced illumination are very interesting. The tree itself must have a lot of yellow in the leaves to reflect full yellow under high lighting. Maybe also be due to high red values from the Sun. I might toss the yellow tree in the bin but that would be a mistake if someone had made the tree to show as in the second photo under reduced sunlight. Thus to get rid of the bright yellow tree and get the second one the user could set time of day or Gamma.
My first photo are of the Trunda trees from the East Kentucky route. I doubt that the author made millions of polygons to provide realistic coloring. The closeup shows what he did and did it very well!
If some talented person can try making a tree with a portion of the leaves looking like those by Trunda that would be a nice experiment. Personally, I believe that is the key to one facet of making the things called Speed Trees look more real. The other is the terrible application of clumps of branches (with leaves). Some people made these as circles which makes a bad looking tree look even worse. Note that the Trunda trees look homogeneous with no "clumps" of branches/leaves. Multicolor some leaves and avoid the cotton ball look and that will be progress.

what's a normal map?
matter of opinion. i dont think that these trees look real at all. the colors are not that great, and they are obviously flat cutouts. the tree you show the closeup of is the least realistic of them all and even when i do use these kinds of trees i cant stand to use that one.
just another boring speedtree hate post.
I get a lot of flickering/glistening from those trees. May be due to his leaves versus the style of others. I have anti-alais set to 4 in the Options.
