creating specified terrain in TG2

[prasad5787]

Hi,

Just wondering how and which way is better to create terrain with a specified height at some particular area or position in the map.

Later on if I know the way on how to do it.

Then I will see the parameter setting or values which will effected and specify my own in my way of experiment through programmatically.
So, my actual query is to manipulate terrain heights in either ways manually or programmatically.

I am new in creating stuff with TG2, so any previous forum url's or suggestions will be a great help.

Thanks in advance...

This is not easy. If you are using heightfields, the operator menu below the terrain tree has a couple of tools to do this. Heightfield Adjust vertical and Heightfield clip vertical might come as close to doing this as anything. The terrain generator in Terragen 2 is not really meant to build exact height data.
You can import heightfields from other programs, World Machine for instance. Or download geophysical data and import that. I think Terragen 2 uses the GIS data system.

You can actually do this in several ways, depending on your goal. Procedurally, you could use function nodes outputting a specific value through a displacement shader set to an appropriate multiplier. This would create a uniform height across the planet, unless you constrained it somehow. Easier might be to feed a Painted Shader into a Displacement Shader and just paint displacement in the area you want, and adjust the Displacement Multiplier to reach the altitude desired. You can check the altitude just by mousing over the area of terrain and looking at the numbers at the bottom of the 3D Preview. Y = up in TG2.

If you have the need to create very specific and complex terrain shapes, an external heightfield editor will probably be easier and faster. World Machine, Geocontrol, Wilbur (free), L3DT, and Leveller are all good options.
