ok so I managed to install KOTOR 2 with Rework Project, fully installed other mods, and have the Visually repair HK-47 mod installed, and when I boot up the game, it didnt crash despite what you said
The Visually Repair HK-47 mod is Open-Sourced. Maybe its possible to replace the textures from that mod with the ones used from HK Droids SWTOR-Style to turn it into a Win-Win situation, where the players can have the interactivity of further fixing HK-47 in action while retaining the said SWTOR textures without breaking the game further.
Will there be a way to make this mod specifically compatible with the HD Rework Project? Its called Visually Repair HK 47 and I became a fan of its mod for adding more interactivity with the said character. While I know its already "firmly inscribed" with SWTOR-Style HK droids mod, I just want to know if I can reconsider it with this mod specifically.
