Thanks. For all who have difficulties making the mod to work (like me), try this:
"Copy TexMod into the directory where the LifeIsStrange.exe is located (...\Life Is Strange\Binaries\Win32)
Rename the original "LifeIsStrange.exe" to eg. ".LifeIsStrange.exe".
Then rename the Texmod.exe to "LifeIsStrange.exe".
Launch Life Is Strange trough Steam --> Texmod will open --> select the modified ".LifeIsStrange.exe" (the original .exe)
Now Life is Strange will launch and the Texmod overlay will appear."

PS: Great mod
