Control (UI) Default Value Function

Anti-aliasing Settings

AA_samples 1 Sets the number of anti-aliasing samples Arnold fires.

The number fired is the AA_samples value squared,

camera rays per pixel.

AA_samples_progressive_begin 1 A negative value sets a single camera ray per block of

pixels. For example, a value of -5 sets one camera ray

for every 25 pixels.

AA_samples_progressive_step 2 Sets the step size for progressive sampling.

AA_filter gaussian Specifies which anti-aliasing pixel filtering kernel to use.

AA_filter_width 2 Sets the width, in pixels, of the multi-pixel filtering

kernel.

AA_sample_clamp The max value of the

variable.

Clamps the value of pixel samples at the given value, or

less. Useful when anti-aliasing extremely bright pixels

with motion blur, depth of field, etc, by clamping the

dynamic range of the pixel samples.

AA_sample_clamp_effects_aovs Off When enabled the pixel samples of AOVs are also

clamped. AOV clamping affects every RGB and RGBA

(except the A component) AOV. Currently, there is no

way to specify which AOV's to clamp and which to

preserve.

Lighting

GI_diffuse_samples 2 Sets the number of samples for indirect diffuse (global

illumination, final gather, radiosity).

GI_glossy_samples 2 Controls the number of rays fired when computing the

reflected indirect-radiance integrated over the

hemisphere weighted by a specular BRDF. The exact

number of rays is the square of this value.

GI_refraction_samples 2 Controls the number of samples used to simulate the

microfacet-based glossy refraction evaluations.

volume_indirect_samples 0
