Yes, I'm pretty sure. You may do what you want, if you like it keep it but these jaggs really are the edges of the quadrangulated terrain geometry. Erm, yes, sorry that I find this a bit crappy...I should explain that this is the reason why I find the whole Terragen a bit crappy... since I dicovered Mojoworld wich really blew my mind. A few words on this prog: it constructs a whole planet out of various fractals with quasi-unlimited detail and adds displacement (not only bumpmaps), but i's a bit more expensive and A LOT more complex. Even Terragens maximum quad count is faaaar below Mojoworlds resolution. Terragen2 is something like Mojoworld I think but it's surely not that cool.
Hope I can help you a bit with these renders (I never really got into bumps and background - shame on me :) ):

- highest or nearly highest terrain resolution - I think there are still some of those jaggs visible
- highest resolution and bigger, smoother features - no jaggs
- a part of your image (hope you don't mind) - can you see how huge your quads are? 1: look at this shape 2: this is the edge of one quad! (between the arrows) 3: hua, all these sharp jaggs are edges and corners of terrain quads

The problem is, that with a steeper (or more jaggy) terrain, the likelyhood of unwanted strong jaggs - due to a lack of terrain resolution - increases. This even troubles Mojoworld, but this prog overcomes it by automatically adding detail until pixel-level detail is reached. However, this greatly increases the rendertime for steep terrains.
In Terragen you'll have to find the balance between terrain steepness/natural jaggedness and terrain resolution. For high-res terrains you should have enough RAM and MHz because this can be a lot slower to render.
I haven't used Terragen for quite some time, the major things I remember which are different in the full version are the terrain size (up to 4000 x 4000 or something) and a much better anti-aliasing option.
At the end of all: thehe, if you like the jaggs, keep them - I'm not sure if those can be achieved with the fractal terrain function in Terragen the way you like it...I don't think so...if you are afraid that other Tgenners may find find this crappy (hehe, like I do, but never mind :) )...well, hehe, do what makes you happy... ;)

Wow, now i see exactly what you mean. There are little abrupt changes in slope at very feined intervals, which is the stretched resolution of the .ter file. I guess i havnt been working with 3d render enough to see these details, but thanks alot for helping me out. I think they if they are seen as a bad resolution by many, im not going to stretch the terrain anymore. Its kinda like using lens flare in photoshop i guess. Even if you think it looks good, and it does look good, everybody knows exactly how you got it and it just taked the goodness out of the picture.

Well i hope that made sense. That was the best comment i have ever receieved. You earned a watch.

Well, I love to explain things and I love to hear myself explaining things :XD: nevertheless I'm a nice guy who generally wants to help :D
I realized that most comments are without a 'what' and a 'why' reading like this:"Whoa, cooool!" Very kind but a bit critique wouldnt' hurt. So I try to make it better and you are one of my first victims :D
Ah, you resized the terrain...now I know, why it looked familiar and unfamiliar at the same time (I never resized).
I'm glad that I could help - and many many thanks for the watch :)
