View Full Version : Landscape flyover from high to low

Hey all,

As part of this snow scene I am doing I need to fly down through some clouds and over a sprawling landscape getting down quite low as to fly through the trees and end up at my clients logo. I sold them on the idea by making a quick fly from the sky to a water plane (through some clouds etc) all good at the water plan is infinite. Now I need to do a HUGE landscape and can't get the ecosystem to look realistic.. the surface looks all crap and stretched and just looks all very ordinary. I have seen on the Vue demo vids some huge city scenes and some landscape fly-overs where the land looks very nice and genuine.

HELP :) Is it a scale issue possible or what? I have a procedural terrain setup, it started as a standard and I loaded in a bmp to be used as the height map (I need a specific area for the logo) and then changed that to procedural. I am using the snow eco-system at the moment which I want to tweak but can't get the standard one to work let alone a tweaked version. I have have altered the plants a little to be what I want and around the logo I am going to paint in a certain area.

I really confused about what I am doing wrong, can someone give me some tips on making a huge landscape that will be seen pretty close up (as well as far away).

Many thanks.

S.

Have you tried using multiple terrains placed close together rather than one huge terrain? the image in my site http://www.artzfx.com/ header has about 4 terrains placed together to create its terrain. I also scale the materials>ecosystem>trees to suit.

What artzfx said. Use multiple terrains and scale them to your needs. It's almost impossible to get fully populated terrains at once. It's just to processor intensive.

There's also a good tutorial on how to do that. Look in your vue help file on the bottom pages for "Building a Complete Scene". It will show you how to use distant planes etc with a realistic look. The other thing you could do when you fly over a large landscape is to search for transistions. When you pass a tree for example use that to morph your background into a high poly model in a new scene.

Consequently, real trees in forests should be used for close-ups only. If
you require a distant forest, it is best you use the second method: Faking
distant forests, which will yield very pleasing results too.
