how to install:

unzip data5 and drop in \Dying Light 2\ph\source

for textures use 010 editor scripts by mlleemiles and inject the "textures" folder into common_textures_0.rpack found at \Dying Light 2\ph\work\data_platform\pc\assets

for the custom icon you will need to do the same with the textures except inject the "custom icon" folder into gui_common_pc.rpack

to install texture mods follow this tutorial: https://youtu.be/q7clS1Kv4RU

thanks to PHM2D for fixing the .model file (i have learned from my original mistake)
