As I have worked on several games, I have noticed various oddities. I have covered one before: unused assets. However, there are a few others. In the game TES:Arena, most SET files are reserved either for walls or for floors. The exception is this one:
Which gives us the below separate ingame dungeons:
So far, it’s the only SET file to do that. Not sure what happened or why it’s like that. The main challenge with is that while I liked it on the floor against the dark walls, I don’t care for it as a wall texture. I’ll have to go back and tweak/balance it later. In theory, with further modding of the INF files (they determine which art files each level uses), it can be made so that a different file is used but I’m not inclined at this time to do that.
Right off the bat, I’ll admit that my “working” copy of TES:Arena has been in use since I first started this project (several years now). It is now a Frankenstein-mess of my experiments. I expanded that executable file with an ancient program, expanded all the resource files, installed “WinArena” over top, fiddled with the INFs, etc. So I don’t know if the weird things I see in the game are my fault or not (easily enough to verify but I don’t really care that much).
I even had a very odd problem of an Imperial City textures completely changing from one style to another. I just walked into a mages guild and came out to a completely different looking city. I wished I had made a video of that weirdness.
