Yet Another Terrain Tool

Yet Another Terrain Tool (YATT) is a plugin for the Neverwinter Nights 2 Toolset allowing importing of terrain information (including heightmaps, colourmaps, texturemaps, etc) directly into the toolset. It does the importation of height, colour and texture data directly through the TRN stream, meaning it's reasonably nice and fast.

To get started, have a look at the Getting Started tutorial. For a more advanced example, which uses all elements of YATT, have a look at the Advanced Case Study, detailing the building of terrain for a steppes area of the IONCROSS module that is currently under way.

Input heightmaps and colourmaps should be sized as follows:

Image Size (Pixels) Area Size (NWN2 Tiles) Area Size (Mega Tiles)
121 4 1
145 8 2
169 12 3
193 16 4
217 20 5
241 24 6
265 28 7
289 32 8

Input texturemaps should be sized as follows:

Image Size (Pixels) Area Size (NWN2 Tiles) Area Size (Mega Tiles)
640 4 1
768 8 2
896 12 3
1024 16 4
1152 20 5
1280 24 6
1408 28 7
1536 32 8

Many thanks to Tanita for much help with the TRN format (take a look at her documentation here) to Victor, LW and the IONCROSS folk for excellent suggestions and ideas, testing and getting me to start this and cliff and everyone else who's been posting about terrain manipulation on the NWN2 forums.
