Issues with Importing

Please check the online version of this manual for the latest update:

Why doesn't my Terragen world look same when imported into 3ds Max?
GroundWiz tries to convert and approximate the look of Terragen surfaces with its own layers as closely as possible. However, in some cases, imported layers might end up looking quite different.
Very important aspects of the final look are also lighting and atmospheric effects Terragen and 3ds Max use and those are not compatible either.

When importing big terrains (million of points), 3dsmax/VIZ crashes - even when using optimization options.
In that case you many want to try Split Into Chunks option. That way your system has a better chance of handling memory requests. After importing the terrain into 3ds Max/VIZ in chunks, you can merge them back together.
