 ## AO bakery for Assetto Corsa
 
-This is a CUDA-accelerated ambient occlusion bakery for racing simulator Assetto Corsa with Custom Shaders Patch, supporting tracks and cars. Made possible with NVIDIA OptiX Prime, forked from [this project](https://github.com/nvpro-samples/optix_prime_baking).

 ## Features
 
 - Tracks:
+
   - Both KN5 and INI files are supported as inputs;
   - Special trees baking (without self-occlusion, with normals facing up);
   - Special grass baking (without any shadows from grass, with normals facing up);
   - Optional trees transparency factor;
   - Skips dynamic objects to shadow them dynamically later on;
   - Baking of extra samples along the track for occlusion for dynamic objects;
+  - Rebaking of overly darken areas with increased number of rays per triangle.
 
 - Cars:

   - Raising ambient brightness to compensate for new AO;
   - Extra pass for adding a bit of light “bounced” from the ground;
 
+- Takes into account light bounces to keep AO brighter;
 - Alter brightness, opacity and gamma for resulting AO;
 - Adjust AO per-object if necessary;
 - Adjust sampling offsets per-object to get rid of arifacts in complicated cases.
 
 ## Tips
 
 - Various options could be changed in `baked_shadow_params.ini`;
-- To run it on CPU, set `CPU_ONLY = 1`, although at least on my PC with GTX 1060 it runs about 
-100 times faster with hardware acceleration (2.5 s vs 4 min for main pass).
+- NVIDIA GPU is required;
+- Works much faster on RTX GPUs, but can also use older NVIDIA GPUs with CUDA, although works a lot slower with those (disable light bounces to improve the speed).
