adapt_to_speed

Use the speed vector pass to reduce AO samples in fast moving pixels. Higher values result in more aggressive sample reduction. Requires Vec pass enabled (for Raytrace Adaptive QMC).
Type:
float in [0, 1]

blend_mode

Defines how AO mixes with material shading. in...
  • ADD
  • SUBTRACT
  • BOTH
Type:
enum

color

Defines the color of the AO light in...
  • PLAIN
  • SKY_COLOR
  • SKY_TEXTURE
Type:
enum

gather_method

Gather Method in...
  • RAYTRACE
  • APPROXIMATE
Type:
enum

sample_method

Method for generating shadow samples (for Raytrace). in...
  • CONSTANT_JITTERED
  • ADAPTIVE_QMC
  • CONSTANT_QMC
Type:
enum

samples

Amount of ray samples. Higher values give smoother results and longer rendering times
Type:
int in [1, 32]
