2 years ago You need to launch it with command line parameters in either cmd or powershell by opening one of them in the folder that has prboom-plus.exe and running .\prboom-plus.exe -iwad DOOM.WAD -file SIGIL_v1_21.wad. If sigil is located somewhere other than the folder that prboom-plus.exe is, you'll need to use its absolute path which you can get by highlighting it in file explorer and pressing Home > Copy path on the ribbon of file explorer. (the command would look something like .\prboom-plus.exe -iwad DOOM.WAD -file "C:\Users\[username]\Saved Games\Doom\pwads\SIGIL_REGISTERED_v1_21\SIGIL_v1_21.wad"). This is the same process that you use for loading mods with prboom plus normally, so if I'm not explaining it clearly enough or you want more information about it, you can find plenty of documentation about it by looking it up. Keep in mind that the creator of this mod has not applied custom lighting to anything other than episodes 1-3 of The Ultimate Doom so it won't look as good as the base game does.
As a side note, if you want to automate this process so you don't need to use the command line every time you launch a mod, once you get the command working how you want it to you can copy and paste it into a text file and rename it to something along the lines of SIGIL.BAT (replacing the .txt extension with .bat being the important part). As long as you place this in the same folder as prboom-plus.exe you can launch it with sigil or whatever mod you configured it with by double clicking this file.
Hi, is it possible to use with external .wad ? I want to play prboom-plus-rt with the Sigil chapter from Romero which is available with 2 wad : SIGIL_COMPAT_v1_21.wad and SIGIL_v1_21.wad I'm a new user into the modding of doom's games and I don't know where to start. For the moment I'm just playing with the rt mod on the 4 originals chapters. Btw, I'm using the original DOOM.WAD from Ultimate Doom.
