hmmm well i cant find much images of what it will look like, so you just make it up as you go along but i will tell you the important aspects of it i want you to make.
Two stories,
Holes in the walls so player can pass through,
the rundown feeling,
windows with no glass,
hole in the roof so player can see ground,
grungy,
and the exterior dosnt have to look that good at all because the player will never get out of the house,
And most of the usual rooms eg: bathroom, lounge room, misc rooms, kitchen.
If you got model pack 3 or any other segment model pack im sure you can just use those textures. And above all enjoy yourself! I'm not making you do it.
And keep up the good work, i'm sure you'll get far
Get one better at better electrical, well we just did, DARKANGEL
