The Japanese Trees Set

for TTDPatch and OpenTTD
developed by TT-Forums members

Version 2.1 - June 2009


The Japanese Trees Set is part of the Japan Set which consists of the following GRF files, available from the Japan Set homepage:

Installation and settings for TTD Patch

For general information on how to use GRF files in TTDPatch, read the TTD Patch manual. The Japanese Trees Set is available in a DOS version ("jptreesd.grf") and a Windows version ("jptreesw.grf"). Simply copy the grf file into the "newgrf" folder inside your TTD main folder and add the entry "newgrf/jptrees[d/w].grf" (with the "d" or "w" depending on whether you are using the DOS or Windows version of TTD) to your "newgrf[w].cfg" file.

Installation and settings for Open TTD

For general information on how to use GRF files in OpenTTD, read the OpenTTD manual. If you have downloaded the Japanese Trees Set from the Japan Set homepage, simply copy the grf file into the "data" folder inside your OpenTTD folder. Alternatively, you can use OpenTTD's online content service, as described here. To use the Japanese Trees Set in a new game, you only have to add it under NewGRF Settings on the title screen.

If you have an older version of the Japanese Trees Set installed, removing the old file and adding the new one will make all your old savegames use the new version. (OpenTTD will display a warning upon opening such savegames though).

Compatibility with other GRF files

The Japanese Trees Set is designed to be used together with the other GRF files in the Japan Set listed above. It should be compatible with any other newgrf, except of course those that also replace the tree graphics.

Known bugs

Currently none. Please report any bugs in the release thread.
