UPDATED November 3, 2018: Updated with a complete overhaul for the set to work properly and look its best with the latest version of GameGuru. While the same images are in the same place with the same names, this update may still require you to do some manual adjustments to your terrain's paint job. This is primarily due to alpha channel adjustments to make specularity work how it should in the latest GG updates, how the new system handles files in general, and is ultimately beyond my control.
All screenshots are taken with the updated version.
If you didn't keep a backup of the original but wish to continue using it, please contact me for information on how to get it from me. It will no longer be available in the TGC Store as I do not believe it is up to the expected or acceptable current standards by any means.
PLEASE NOTE: This set was made for the old terrain system in early 2017 and still functions there just fine in the newest versions of GameGuru. The textures are also compatible with the new 16 texture system but may require extra efforts.
Remember, terrain images can be switched out and rearranged with other sets. If you don't like part of a set, get creative and rebuild it with files from other terrain sets. (Always make copies and be careful!)
TIP: You may need to delete the auto-generated files in the terrain's folder to get the new textures to show up on your map.
