So i've been playing WOWS for a little while now and figured i wanted do start with some basic modding. Nothing exiting so far - as this will be my first modding ever - but just painintg the ships a little bit. I figred this may be the right game for it as such mods will only be on the client side. So i downloaded the WOWS Unpacker tool but can't find any .dds files. For example: i want to work on the clemsons skin so it should be the ".....a.dds" file but i can only see and extract .geometry and .splash files. Have they changed the fileformat since this guide? Am i missing something? Thanks in advance for helping a newbie with modding. EDIT 2 mins. later: I think i found it, i will try to work with it. Edit 3: I found the correct file for the clemson i think but unfortunately i'm not able to mod this. For the very first test i dont want to take any effort whatsoever - i just wanted to see if it works. It doesn't. I created the res_mod folder and the according filestructure and painted a wild line on the file. Exportes it as a .dds fileformat and it changes: nothing. I will send some screenshots below. Any Ideas?
