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.
