Union Island is one (of 32) island of St Vincent & the Grenadines. Located in the Caribbean sea, it has a population of around 3000 habitants. The summit reaches 999 ft (304m). It's a paradise for wind surfing. Driving? not so much... Luckily my roads aren't accurate, and made of asphalt, instead of the concrete real ones!

I took a lot of liberties redoing the island. I made it to scale, but the roads in real life are limited and all made of concrete. The West only has forest path for example, whereas i made perfectly raceable roads all around.
Please note it is not a racetrack, and you should drive accordingly :)

Everything is made from scratch with my own two hands. As such, please respect my work and don't use it elsewhere without my permission. And please don't modify or edit it in any way, trust my choices.
It's also my very first track, so expect broken things. Feel free to : report stuff.
Also please do read the FAQ below among the rest ;)

- Freeroam : 30+ km, 45 pits, no AI line, no cameras, no race start, one time gate in Ashton if you want to create your own lap
NO AI line means NO cameras. You could always copy the ai + camera from another layout, but it will never cover all the roads
- Scenic : 17.5 km, 24 pits, AI line, Cameras, hotlap/race/weekend, physical bales
- West : 12.2 km, 24 pits, AI line, Cameras, hotlap/race/weekend, physical bales

- 700.000+ tris FFB road mesh
- collision for most objects
- LOD distance set on most objects
- Fully covered terrain with bush & trees, the old fashion way
- camTool set by Atrupelador : here

Recommended (Not mandatory) : 0.1.76
Night lights, rain, csp grass
tips : in ext_config.ini I turned off the lights_series (keyword : "heavy" ) that were causing heavy framerate drop. Feel free to turn them back to ACTIVE = 1 if you want the full night experience. Mostly the light being casted from the windows at night.
-Traffic not working ?
and presets here (remove space and dot, you know) https:// acstuff dot ru/s/0dmn0S

-Cameras for Freeroam ?
Cameras need AI line. No ai line means no camera. Besides, even if, you couldn't cover every road, so would end up often with a wrong camera.​
For your own use, you can try copy the ai + camera from another layout​

-The road is very bumpy
i've tried and create a believable road surface, with its imperfections, as you'd find in real life. It is not a racetrack. Try and set softer suspension !​
-I have low framerate ?
V0.8 see great improvement in FPS, if you still have low framerate, maybe try renaming extension folder to remove all CSP features, see if that helps​

-My game crashes ?
The track works for many, make sure you test with a kunos car, and recommended CSP / sol version. Check with another track etc. You can also try to rename the extension folder, see if the track runs without any CSP features​

-My game looks dark/bright ?
Check other tracks to compare. Check my screenshots or videos people made on YT, if it doesn't look like that, try backup your settings and reset to detault. You may also reinstall a clean version of CSP / Sol.​

-CSP water for the ocean ?
Very much NO.​
CSP water presets are too limited. It looks silly, the sea isn't a mirror, check actual photos​

-VAO patch ?
Don't you dare come up with a vao patch none-sense for my track and insult the hours i spent baking my own ambient occlusion on props and terrain​

Once upon a time...
After helping Phoenix on LA Canyons, and PCH more recently, i always wanted to try and create my own roads. Being in control of the whole process of creating a track from scratch, and see how that exercice would work. It just needed said track. I lived 7 years on the island of Cyprus, and really wanted to recreate the feeling i had back there driving the Caterham. But not being there anymore would prove difficult to get the references etc. since Google map is limited to visit the island.

Time passed, and one day, out of the blue... as i was exploring the globe with Flight Simulator, i flew with a jet from Trinidad & Tobago all the way to Puerto Rico, no gps, just following the flow of islands. That's how i got the idea of making one for Assetto Corsa. And how fun it would be to have a "complete" map surrounded by water, something that's never been done (to my knowledge). First i thought of Canouan island, which is 30km away from Union Island. The shape looks cool, although a bit narrow. Then flying around a bit more, i passed Union Island and thought that was it.

screenshot from MSFS the 9th of november

Next thing you know i gathered all the nasa imagery i could find, and elevation data and jumped in 3dsmax. As soon as i got a free weekend i started working on it 3 days in a row like an impatient kid. After which i had an early version, naked terrain, basic barrier not to fall at every corner, and very early version of driveable roads

21 november 2020 :

A week later, random palms, planted road
28 november 2020 :

and so on... i wish i was more organized and did a proper timelapse progress !
But i remember the first drive was phenomenal. The feeling of driving on a track of my own creation, built from an empty scene felt surreal.
Quickly i really wanted a Test Drive Unlimited feel with a full "around the island", and this is what became the Scenic layout. It is not half an hour drive like the original, but with 17km and not all perfect asphalt, it certainly is challenging to master !

There's been a lot of experimenting, reading tutorials, and more experimenting. But almost 400 hours later (see details here), it starts to feel a bit more vibrant and alive than the screenshots above :p
And now, even though it's not finished and perfect as i'd like it to be, my wrist is calling a stop as i've spent more than 70 hours last month alone, on top of my actual job... Decided it was time to share it and take some well deserved time away from the computer !
There's still lot of things i want to add and polish, so stay tuned for later updates...
- add details in towns (ground floor shops, markets etc.)
- add few more roads following existing ones
- improve side road transition (!)
- merge any soil texture with terrain mask
- add "race" detail for timed layouts
- add easter eggs (most important part)
- redo a FFB mesh using the visible types of tarmac
- improve performance (reduce 99% cpu when lot of AI !)
- improve AI line. They do crash a lot at the first corner on West layout ... and in the harbor on Scenic
- any bug or issue, please check with a default kunos car, with/without Shader patch, and then report it on the discussion thread
- please note; modders aren't responsible for CSP breaking stuff every now and then :)

I live in a LHD country and I am learning to drive RHD cars. Union Island is a perfect map for me.
As a fan of freeroam maps in Assetto Corsa, this one brings wonderful TDU vibes and is a joy to drive around.
love this island ....thanks mate
Amazing, but would prefer asphalt roads for immersion sake. Cheers!
For me definetly the best open world map in Assetto Corsa, i hope there will be update soon, keep doing good work.
Great. One of the best maps
This is absolutely fantastic, even better in VR. I've never been to the island for real, but I want to now. Great fun exploring the island and all the side roads and beaches that are available to roam freely. Really excellent work
Absolute insane
it takes me back to puerto rico really nice beautiful
its beautiful brother. im blown away by the attention to detail. thank you
Spectacular scenic route! Best driven with 911 Singer, both made by Ben O'Bro. Both mods are quite legendary!
Once got lost in the island and used Google Maps to find our way back to the spawn point. 5/5
Awesome track, especially with traffic. Love testing new cars and seeing how they can handle the tight island roads.
Still the best and beautiful free roam map for assetto corsa for me!
Great work! We need more of this quality mods out there!
Amazing, thank you for your hard work! I've only driven this map a handful of times but I can already say that this mod is a labour of love from a quality author. A perfect 10/10(5/5) in my books!
This is the most beautiful freeroam map there is, I LOVE IT!!!!!
The ultimate Assetto Corsa free roam map
Literally I can't describe how good this thing is. I am simply speechless. What I would like to see is more raceable layouts with AI. I imagine the COULD be a lot of them.
