Here is a modification that will change the inside and outside of most of the Save Houses including the Johnson house and Grove street. This modification also changes the inside and outside of the Maddog Mansion.
Johnson house and Groovestreet are changed inside and outside,
the Madddog mansion inside and outside and all interiors
for all savehouses except for the hotels.
It's a large texture mod but a lot has to do with each other
that's why I put everything in one mod
Just use the img tool and open gta3 in the models folder for:
and open gta_int in the models folder for:
all other files
