//AMBIENT OCCLUSION - GLOBAL PARAMETERS
#define AO_METHOD 3 //[1 to 2] 1: SSAO | 2: Raymarch AO | 3: HBAO | 4: SSGI
#define AO_SHARPNESS 0.5 //[0.05 to 2.0] 1: AO sharpness, higher means more sharp geometry edges but noisier AO, less means smoother AO but blurry in the distance.
#define AO_DEBUG 0 //[0 to 2] Enables raw debug output. 1: occlusion | 2: color bouncing (SSGI only!)
#define AO_LUMINANCE_CONSIDERATION 1 //[0 or 1] Enables dampening of AO intensity on bright pixels, to preserve bright light sprites or beter lit areas. Not for GI!
#define AO_LUMINANCE_LOWER 0.2 //[0.0 to 1.0] Lower brightness threshold where AO starts to fade out. Below this threshold AO has full power.
#define AO_LUMINANCE_UPPER 0.7 //[0.0 to 1.0] Upper brightness threshold where AO starts to fade out. Above this threshold AO is 0.

//AMBIENT OCCLUSION - SSAO
#define iSSAOSamples   128 //[32 to 128] Amount of samples. Don't set too high or shader compilation time goes through the roof.
#define fSSAOSamplingRange 50.0 //[10.0 to 50.0] SSAO sampling range. High range values might need more samples so raise both.
#define fSSAODarkeningAmount 0.2 //[0.0 to 5.0] Amount of SSAO corner darkening
