Hi, I was Looking for a Mod to Replace "Open World - No Borders" & " SGsUA- No Borders at FallOut3", cause I like Height, and going around things to get to right spot, to be Naughty ...
I Couldn't find a MOD here that did this, SO I (being adventurous Idiot), Just installed Both in NewVegas Load order, UMM, it works it seems so far ...
I noticed Discussion above about Drawing terrain on the Fly, These Mods do, I know the Fallout NV mod, seems to roll on for 100's of miles, but I got bored, as just terrain, so maybe something to look at, with a Random encounter generator for Baddies, Goodies, Critters, "civilization", may muff vast areas, so you are not Alone ...
Just a Thought ...
P.S. No the FO3 mod didn't work like that, I have to reinstall in FO3 then rebuild T2W, I am getting up to speed .. hehe
