Edit Sept 2021: This is now obsolete, please use ContentManagers built in LOD generator, its much better and has lots of options you can fine-tune.

Full automatic LOD creation for Assetto Corsa cars - v1.0 by Kavoriken - v1.x by leBluem
Instructions in included "\LODfolder\Readme.txt".
This involves a (free) Simplygon license created along with an acount at https://account.simplygon.com/
Simplygon SDK 8 only works on Windows 10.
Its most usefull for mod cars with no LODs at all. If it has packed "data.acd", you have to unpack it to "\yourcar\data\" and delete it, to include the new LODs created. However its goal would be to decrease object count, which is only done 40% from i.e. 139 downto 83. So its questionable if it does help on performance, done no benchmarks so far.
If you have your AC in default steam-folder, LOD-Generator will not work.
The batch file FAILS on folders with SPACES, if you have AC installed like this:
-> then - before using "LOD-Generator" - copy the car folder somewhere else, into a folder WITHOUT spaces!
edit: quick benchmark ;( Ford Transit, Monza 66, 20 AI
-----------FPS min max avg
no lods at all: 47 59 53
generator lods: 50 61 55
original lods : 55 70 64
LOD - LevelOfDetail; smaller, less detailed model of the car at a distance, AC uses 4 levels in total.
Example: Original LOD A of the FORD Transit: 239k tris + 139 Objects, if anyone can provide a better simplygon ".spl" file, this would be great!
LOD B, 34.5k tris + 117 Objects:
(-manual made example: 30k tris + 78 Objects, not shown here)
LOD C, 8.3k tris + 87 Objects
(-manual example could be: 8.6k tris + 35 Objects, not shown here)
LOD D, 5.6k tris + 74 Objects
(-manual example could be: 2.4k tris + 2 Objects, not shown here):
