This is a blank tileset, similar to the one that comes with the Bioware export scripts download. There are aurabases set up in a grid, with letters and numbers running along the sides to denote the grid position.
Also, there is a MAXScript that will rename the entire tileset using the prefix and variation numbers that you provide in a rollout utility.
This is a screenshot of the tileset open in GMax, with the Renamer open in the utilities tab. The Renamer is a very simple rollout that will allow you to rename the aurabases, primary lights, and secondary lights just by inputting the prefix and variation number and hitting a button.
