Legend of Grimrock is a modern take on the classic dungeon crawling RPG in the style of Dungeon Master and Eye of the Beholder. After playing through the main campaign, I started to get involved with the Grimrock Modding Community, something that ended up being a lot of fun. If you’re partial to some modding yourself, and enjoy classic dungeon crawling, you could do a lot worse than get involved with the very friendly and talented Legend of Grimrock Modding Community.
While working on rooms for the multi-modder ‘Round Robin’ mods, as well as my rather ambitious mod for Legend of Grimrock, I found a few things to be a little bit of a pain in the backside. One of these is piecing together sprite atlas files that are used for the icons representing items that are in your hand or your inventory. This seemed like a good opportunity to crack open Qt5.0 and make a tool!
Today is the release of version 0.1.2 of the Grimrock Graphics Atlas Toolkit (GGAT), an application built on Qt and the Nvidia Texture Toolkit to collate PNGs into graphics atlas files and then export them as DDS files for use in Legend of Grimrock mods. If you’re making a Grimrock mod, then no more will you have to carefully line up your icons in Photoshop to make sure they are centered - simply drag and drop your files onto the toolkit and hit Export. It also shows you the gfxIndex you will need to use for your item in your mod’s lua scripts.
