------ Installation -------
Install Cleo4 if you dont have it search google for gta sa cleo4
To install use any img tool (preferably Alci's IMG Editor (i like this one)) to install the folder named "imgs to replace"               
open alci or other img tool; first search and open gta3.img in your models folder which is in your gta sa folder and import the files from
the folder "to gta3.img" then save and open gta_int.img and import files from "to gta_int.img" then save and exit.
Then just drop the Models, Data and Cleo folder in your root gta sa folder and let it replace the necessary files, feel free to examine 
the files before you copy em i also put in my particles in the "my particles folder" incase you might like it, the only thing it replace in particles is transparent
clouds so you can edit yourself if you know how... im tired now so i wont explain every detail you've got common sense so you can figure it out
Simple as that.
make a backup if your not sure your game will crash just a warning this mod is safe but at you own risk ok

----- Report ------
Your probably wondering what makes this skybox different from the rest... Well some of em have savegame problems which make you cant load a saved game
i didnt have to fix that cuz it was already fixed in this update....
THE MAIN PROBLEM FOR ME IS THAT YOU CANT GO UNDER ANY PLANE OR CAR OR PED CUZ THEY DISAPPEAR AND GUESS WHAT.. i fixed that yay!!!!!!!!!!
Im a noob scripter i just started scripting and i taught myself.. i took this mod before i could create a script myself.. i loved this mod
it added reality but guess what plane go by by i didnt like that im trying to create the realest gta ever so i cant have chaos in here 
so i started scripting because of that, thinking i could fix it.. it payed off.. the first thing ive ever scripted worked
i combined the ticket mod and the mostwanted mod to make whenever i speed and a police saw me they would either let me go or chase me to give me ticket
a huge success for a first time scripter it wasnt a big deal for an expert scripter cuz i just took two guys mods and made em better but it was a big step for me
imma put that mod in here so you can sample it.... consider it a bonus :)

------ Bug Bug fixed ------ (I Labeled this bug "A BIG COCKROACH")
The problem was (i hope the orginal author is reading this ) the clouds texture had to be loaded on a player(for names sake call this player cloudbot) 
who was loaded on the original player the problem is that when the script reloads also does the player(cloudbot) respawn over and over and whenever textures
(mainly cars and peds) reload they overwrite other textures causing them to disappear so what i did was instead of putting a cloud on a player on the 
original player (cloud-player-player) i put the cloud back on the cloud again then on the original player (cloud-cloud-player) beacuse this texture was
more like an object than a car or player so it did not cause the overlapping on the plane... Genius right 
It took me three day of almost giving up to figure this out i tried every other method i first found this out when i put the cloud on the orignal player
the clouds rotated with him but planes did not disappear so it hit me cloud on cloud :)
One last thing... mod the timecyc at your own risk ya might lose the skybox view.. ide just use the one that i provided if i were you.
Enjoy.
