While I haven’t found my most recent version of the Torchlight mod, I did find my proof of concept file for a texture mod of the pc game Darkstone. Although all the Darkstone media assets are stored in “container” files like my other projects, Darkstone art files are a little different when extracted. Unlike Torchlight and Morrowind that have individual files for each image, Darkstone has what I call “image sheets”. I posted about it before but that was quite some time ago. Basically, it means that one “sheet” will be composed of many images fit together like a puzzle and in reality is actually a dozen or so art assets in one “sheet”.
Arena and Minecraft “sort of” do something similar. Both of them use a combination. Arena has multiple file types for art assets (some undecipherable) which include IMG files (single image) and SET files (multiple art assets stacked on top of each other in one picture). Minecraft *has/had individual files for items and such and one big image sheet for all environmental “blocks”.
*Newer versions of Minecraft are all separate image files
The difference in the Darkstone “image sheet” is that all images are not the same size. It takes a little extra experimentation to figure out where some textures start and where some end especially for textures like grass and sand that blend together naturally already as it is. Depending on my needs, I’ll either use the solid blocks of color or shapes (number, letter, etc).
As I said, my Darkstone work was merely in the proof-of-concept stage. I had only completed 1/2 of one texture sheet. It was enough to redo some grass and road as well as the trees of only the beginning town (textures aren’t shared across levels). After finding my “sole” texture file, I fiddled with a little and worked on the rest of the grass and road for the level (which included a second image sheet) . However, it is all in the draft stage and needs major cleaning up before I would be happy with them.
I have revised the cobble stone to be less “busy”. I tried to use the same style as the other colors (outlines lighter than interior color) but the game keeps altering the colors so I think it can’t handle subtle shades of gray and black. Whenever I get back to this project, I’ll clean up the lines and make sure the grass isn’t so…squiggly.
