As you might notice, your grid won't have a line for the uneven numbers because in the data the game uses half a tile as well (0.5, 1.5 or 2.5). If you want your grid to have a line bordering for example a 3x3 sized barracks, you can change the scale to 0.375, but keep in mind that one square in the grid is now only half the size of a tile in game.
It is best to name them the same as the internal names in your data files.
Examples: BLAC2N1E, CSTL3NNF, ARCHR_AN, TKNIT_SN, ...
Here I usually use two parts separated by an underscore, describing the nature of the object and its orientation or location.
Examples: cam_target, front_wall, left_forearm, ...
Same as the object names, it is two parts separated by an underscore. The first part describes the type and the second part the material or pattern.
Examples: cloth_crosshatch, wall_stone, wall_wooden, ...
When you download a texture image from the internet they often have long convoluted names, so make sure to rename them similar to the texture in blender.
See you there,
