Lighting > Ray Depth

GI_total_depth 10 Sets the ultimate limit on ray depth, regardless of ray

type.

GI_diffuse_depth 0 Sets the number of bounces considered for global

illumination (0 = Off).

Note: Expect substantial increases in render times with

each incremental rise in the value of GI_diffuse_depth.

GI_glossy_depth 0 For glossy reflections, sets the number of times a ray

can bounce off a glossy surface (0 = Off).

GI_reflection_depth 2 For reflection rays (AI_RAY_REFLECTED), sets the

number of times a ray can bounce off a reflective

surface.

GI_refraction_depth 2 For refraction rays (AI_RAY_REFRACTED), sets the

number of times a ray can pass through a refractive

object.

Lighting > Auto Transparency

auto_transparency_mode shadow_only Selects the transparency mode.

auto_transparency_depth 10 Sets the number of allowed transparency hits. When set

to 0, objects are treated as opaque.

auto_transparency_threshold 0.99 Sets the threshold value for auto transparency.

Lighting > Environment

background none Sets the path to a background material or shader (such

an a sky_HDRI shader), if one is defined or inherited.

Lighting > Environment >background_visibility

AI_RAY_CAMERA Off Objects visible to the camera.

AI_RAY_SHADOW On Objects visible to shadow rays.

AI_RAY_REFLECTED On Toggle reflection rays on or off.
