You not must to add real GTA V Map into SA,you can create fake GTA V Map,that there are high mountains like in gostown paradise 6, but the road cornering reproduced again, to make it more realistic like GTA V, you also have to add a big city, namely los santos. for this, you take it from SA, but rotated 90 degrees to the right, so that similar los angeles and gta v. to the countryside on a mountain, you made all the desert texture, high in quality, and the mountains that must be considered. Mount Chiliad should not be like a mountain, but it was like a hill. to make a mountain in north hollywood los santos, make sure the high mountain coordinate:
so it looks like an elongated mountain in GTA V. you know? because GTA V for PC has not been released, so we do not know exactly from corner to corner of the other end there is any object. better we make GTA V map fake, and once again, this is important:
Mount extends the Z coordinates 500
Los Santos which in turn
villages with high quality
and HD textures
I support you to make this map !
