terragen 2 terrains

(king_troll) #1

a simple way to make terrains is tg2 :

Terragen 2 site

1>double click on the heightfield generator object in located on the terrain node [ the bottom right window ]
2>in the new popup panel, to the side of the new height field checkbox, replace values 1000 | 1000 with 310 | 310, this is the amount of polys and smoothness, below enter the unit terrain size 32,768 | 32,768, and then click on the generate button
3>right click on the heightfield generator object in located on the terrain node [ the bottom right window ] and choose [ heightfield export LWO ]
4>right click on the heightfield generator object in located on the terrain node [ the bottom right window ] and choose [ heightfield adjust verticle ]
5>in the new popup panel, check the [ set height range ] box, and lower the hightest slidebar, to make cliffs/hills around the terrain
1>double click on the heightfield export LWO object in located on the terrain node [ the bottom right window ], and export the terrain

very cool. thanks for this

when you have finished, save the project off, and on the terrain node, add a heightmap erode, and make it rain a million years

Hello thanks for this tutorial,
Can it be done with TG2 free edition? apparently max size with free edition is 800x600, or is there a way around?

thats just the render image size, the terrain grid isnt limited, like most other programs in free editions

you can still make skyboxes with render image size of 512x512, and generate some new terrain textures with displacement shaders overlaying each other and the camera facing down, then use an external app to make them seamless tiles

to generate some terrain textures :

1>click on camera toolbar button

set position to : xyz: 5000, 430, 5000
set rotation to : xyz: -90, 0, 0

2>click on shaders toolbar button

add a new layer/displacement shaders/image map shader, select an already existing terrain texture, and apply some displacement, and repeat this with a few layers

3>click on renderer toolbar button, and the ./full render image size of 512x512, and render image, to export the image, click on the sequnce/output tab, and render sequence button

you can get some existing terrain textures from the game or : http://www.texturemate.com/category/image-galleries/dirt and grass categories

you with need to set the gamma on the effect tab of the render image to around 1.3, to look good ingame

a means of having some form of control of what your terrain looks like :

make a basic terrain in blender etc, no need to smooth it out, and no need to have the full terrain size of 32,768 x 32,768, you can fractalize it by adding heightfields to it before exporting from terragen 2

1>right click on the heightfield generator object in located on the terrain node [ the bottom right window ] and choose [ heightfield load ], and choose your basic lwo terrain model
2>on the new [ height field load ] node, right click and choose [ height field resize ]
3>check the resample pixels checkbox, and enter the values 310 | 310 [ 170 is better ]
4>below, resize in meters to 32,768 | 32,768

you can use terragen classic terrain sculpture tools, and export/save its terrain to a .ter
