| ## AO bakery for Assetto Corsa | ||
|
|
||
| AO bakery for Assetto Corsa, powered by NVIDIA OptiX Prime, supports tracks and cars (and requires **v0.1.25-preview194** version | ||
| of Custom Shaders Patch to work). | ||
| 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). | ||
|
|
||
| To run it on CPU, open `baked_shadow_params.ini` and set `CPU_ONLY = 1`, although at least on my PC with GTX 1060 it runs about | ||
| 100 times faster with hardware acceleration. | ||

|
|
||
| More detailed description and proper documentation are coming soon. | ||
| ## 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; | ||
|
|
||
| - Cars: | ||
|
|
||
| - Full LODs support, as well as COCKPIT_HR/COCKPIT_LR; | ||
| - Special processing for seatbelts; | ||
| - Special processing for rotating objects to keep shadows uniform; | ||
| - AO splitting for doors, steering wheel and other animations, allowing to transition between AO values realtime ([demo](https://gfycat.com/felinepassionateangwantibo)); | ||
| - Baking shadows for driver; | ||
| - Baking shadows from driver in an alternative AO set; | ||
| - Raising ambient brightness to compensate for new AO; | ||
| - Extra pass for adding a bit of light “bounced” from the ground; | ||
|
|
||
| - 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). | ||
