Send to Arion stand-alone: Exports the current 3ds Max scene to a .RCS file and opens it in Arion stand-alone.

Export .rcs: Exports the current 3ds Max scene to a .RCS file.

About: Opens the about dialog.

Version: Opens the version dialog with information about the current Af3 build number, date, core version etc.

License manager: Opens the license manager dialog to install a license file.

Globals

This rollout lists global engine parameters that affect the entire rendering process, regardless of any other setting.

Render settings

Subframes: Defines the number of animation subframes or ticks. This parameter is used to create coarser or smoother motion blur sampling.

Hours: Sets the maximum render time in hours. It can be used along with the Minutes and Passes termination triggers. The first criterion met terminate the render.

Minutes: Sets the maximum render time in minutes. It can be used along with the Hours and Passes termination triggers. The first criterion met terminate the render.

Passes: Sets the maximum number of passes to be rendered. It can be used along with the Hours and Minutes termination triggers. The first criterion met terminate the render.

G-Buffer: Defines a path and a filename for the Arion 32bit floating point G-Buffer export in .HDR, .EXR and .AGB file formats.

 

For more information about these settings, please refer to the Passes vs. time AKB page.

Display properties

Stereo: Enables stereo rendering in true stereoscopic (left eye and right eye) and various anaglyph modes.

Splatting: Enables frame buffer Splatting for smoother anti-aliasing.

Dicing: Enables the dicing feature, which splits the frame buffer in many small sub-buffers to conserve memory for very large renderings. This feature is also helpful when rendering with many AOVs that may use a lot of memory for the frame buffer.

Under-S (Under-Sampling): Enables Under-Sampling. This feature is only used for interactive navigation and the first passe of regular renderings. It has no impact on the final output whatsoever.

Super-S (Super-Sampling): Enables Super-Sampling. This feature greatly reduce (or eliminate) aliasing artifacts on hard and/or bright edges.

Object region: Enables Object Region Render. This features must be used along with per-object Common object properties.

 

For a complete description of these settings, please refer to the Display settings AKB page.

Sampling properties

Mode: Sets the current engine's sampling method.Two options, Unbiased sampling (PT) and Unbiased sampling (MLT) are available.

Mutations: This parameter only applies to the unbiased MLT sampler. It defines the ratio of fresh vs. mutated samples. The default setting is usually a perfect trade-off.

GI spec: Defines the maximum number of global illumination bounces for the specular components (mirrors, hard reflections...). When the checkbox is ticked, it lets you define an exit color to return when the bounces limit has been reached.

GI glos: Defines the maximum number of global illumination bounces for the glossy components (rough plastics, sanded surfaces...). When the checkbox is ticked, it lets you define an exit color to return when the bounces limit has been reached.

GI diff: Defines the maximum number of global illumination bounces for the diffuse components (lambertians, clay...). When the checkbox is ticked, it lets you define an exit color to return when the bounces limit has been reached.

GI refr: Defines the maximum number of global illumination bounces for the refractive components (glass, water...). When the checkbox is ticked, it lets you define an exit color to return when the bounces limit has been reached.

GI SSS: Defines the maximum number of global illumination bounces for the sub-surface scattering components (translucent objects, soap...). When the checkbox is ticked, it lets you define an exit color to return when the bounces limit has been reached.

Specular: This parameter defines the roughness range that will be considered specular for the compositing channels. Any roughness above this threshold will be considered glossy.

Diffuse: This parameter defines the roughness range that will be considered diffuse for the compositing channels. Any roughness below this threshold will be considered glossy.

 

For a complete description of these settings, please refer to the Sampling settings AKB page.

Feature analysis

This section is mostly for RandomControl staff to help isolating bugs or verify that a feature is working. But there's available in the user interface for convenience anyway.

 

No smoothing: Disables normals smoothing.

No DOF: Disables depth of field calculation (this produces a pinhole camera render).

No dispersion: Disables chromatic dispersion of light through dielectrics.

No emitters: Disables all geometry emitters.

No bump: Disables bump mapping.

No instancing: Disables instancing and point clouds. This will make the source object for all shared instances to not be rendered as well.

RCM overr (RCM override): Defines a custom material to override the entire scene's materials (except emitters).

Instant: Renders any of the subframes of an animation.

Wireframe: Renders with a black wireframe overlay of the geometry topology. The thickness value is in millimeters and is scene dependent.

BSDF clamp: This feature clamps the maximum allowed power output from the material's BSDF model. In practice, it reduces (or eliminate) unwanted caustics (often seen as fireflies). High values clamp less, low values clamp more.

AOVs

In this rollout are listed all the available render channels (AOVs) available in Arion for 3ds Max.

For a detailed explanation of their use, please refer to the AKB Compositing channels page.

ArionFX

It's possible to modify or alter the render interactively through the ArionFX Panel. These settings are saved with the scene, while the interactive panel will show up next to the frame buffer while the render is being computed and is not saved with the scene.

Tonemapping

Operator: Displays a list of tonemapping operators presets.

ISO: Controls the film sensitivity to light like on a real camera, but it does not add noise.

Gamma: Defines the output gamma for the frame buffer.

Brightness: Controls the frame buffer brightness.

Contrast: Controls the frame buffer contrast.

Saturation: Controls the frame buffer color saturation.

Filtering

Whitepoint: This feature works in way similar to the white balance on a real camera.

Lens aberration

Amb: Enables the Ambient (the sky or Arion IBL depending which one is used) LightMixer layer calculation and editing.

Sun: Enables the Sun LightMixer calculation and editing.

Lm1: Enables LightMixer layer 1 calculation and editing.

Lm2: Enables LightMixer layer 2 calculation and editing.

Lm3: Enables LightMixer layer 3 calculation and editing.

Lm4: Enables LightMixer layer 4 calculation and editing.

Lm5: Enables LightMixer layer 5 calculation and editing.

Lm6: Enables LightMixer layer 6 calculation and editing.

Lm7: Enables LightMixer layer 7 calculation and editing.

Lm8: Enables LightMixer layer 8 calculation and editing.

RCM media: Defines a material name to be used as participating media simulation. When ticked, the participating media computation is enabled.

Viewport

This rollout allows to control the 'viewport camera' settings, since they do not exist anywhere else like regular cameras.

Stereo IPD: Controls the inter-pupillary distance for stereo rendering.

Roll: Controls the camera roll angle.

ISO: Controls the film sensitivity to light like on a real camera, but it does not add noise.

Shutter: Controls the camera shutter speed.

Safe frame: Renders a safe frame overlay on the frame buffer.

Distortion: Controls the barrel (positive value) and pincushion (negative value) lens distortion.

F-Stop: Controls the aperture opening of the virtual camera.

Angle: Controls the diaphragm rotation.

Film shift X: Controls the tilt-lens shift along the X axis.

Film shift Y: Controls the tilt-lens shift along the Y axis.
