gibbert Posted March 12, 2024 Share Posted March 12, 2024 Hi everyone! This is my first time writing on here. I have recently taken interest in modding Rotwood for the fun of it, even though there is no official mod support yet, and I decided to try extracting game assets (textures and anims) to have a closer look and perhaps adding in custom assets. I came here to share my findings along as hoping to find some help and guidance to decompile the anim.bin files. Rotwood .tex files can be decompiled using instant-noodles' Griftlands file converter tools (GitHub: https://github.com/instant-noodles/gltools). If the .tex format is truly the same as Griftlands then the data includes the header (the KTEX magic string and another mysterious 5 bytes sequence which I assume is like a serial number that cant be changed) and the image data (the rest of the file). As for animation files, I could only get them to be partially read by simplex's ktools (original repo: https://github.com/nsimplex/ktools) *fork used is dstmodders/ktools because it's more recent and being the only one I could build on linux with up to date dependencies: https://github.com/dstmodders/ktools Simply using krane on Rotwood animation files will not work, though. Here's the workaround I found: 1. Use gltools tex to png converter to convert the atlas texture to png. 2. Use ktools ktech to convert said .png file into a ds compatible .tex. 3. Finally, use krane to decompile build.bin, anim.bin and atlas-0.tex to scml. Unfortunately krane didn't succeed and I expected that, however I was able to gather some info about it: > krane -vvv . . Loading build from `./build.bin'... Loading atlas from `./atlas-0.tex'... Loading anims from `./anim.bin'... Animation file has unsupported encoding version 5. WARNING: Animation has unsupported encoding version. Skipping animation file. ERROR: No animation found in the input files. So it can read build.bin just fine, but anim.bin has encoding version 5 as opposed to version 4 in dst. Running krane again with the verbose level 3 (i think?) gave more information: > krane -vvv . . Loading build from `./build.bin'... Loading build information... Got build version 6. Reading build name... Got build name: npc_hunter Reading atlas names...

ERROR: No animation found in the input files. There's a chance that this might be because of the .tex file that i converted, but really I have no idea. I tried putting in debug cout lines to inspect some variables like framerate and coordinates but it did no help. I also tried comparing various dst and Rotwood .bin files in a hex editor but I couldn't find any useful patterns either :/ So I am asking on Klei forums if anyone can point me to the right direction, I would really really appreciate any help! Thank you so much to instant-noodles and simplex for the amazing tools that helped me get this far, I also learned so much reading the two projects' source code.

Thank you again for the great tool, I had some issues with file not found path errors when converting tex files that are not in the same directory as the scripts, so I made some changes to the gla2p script to fix that, I think it's because of working directory mismatch when calling glt2p via the os shell, so I just imported gltex and called its main() directly. Also I changed the output folder's name to use the input file base name so you don't have to deal with the output folder after every convert when you're extracting multiple files, pretty convenient for automation too. Below is the updated gla2p.py gla2p.py It would be nice if there was a repository for this (I couldn't find one so I posted it here) Link to comment https://forums.kleientertainment.com/forums/topic/154884-decompiling-rotwood-game-assets/#findComment-1716492 Share on other sites More sharing options...
