Bevel edges in Maya

Maya 2018

  1. Select edges.
  2. Press Ctrl + B to create the Bevel.
  3. Set the Bevel settings in the tool settings floater.


Arnold for Maya Motion-Blur

Maya 2018 | Arnold 5

  1. In the Render Settings window, Arnold Renderer tab, under Motion Blur,
    Check ‘Enable’.
  2. Set the ‘Length’ attribute to set the Motion-Blur size.
    * the default length of 0.5 means the Motion-Blur will be calculated as a result of a photographic exposure duration of half of a frame duration, or 180 degrees in cinema camera terminology.
  3. Raise the number of Keys to accurately simulate Motion-Blur for very fast rotational motion like helicopter propellers and car wheels.


To generate a Motion Vector (Velocity) AOV (also referred to as ‘Render Element’ or ‘Pass’), in order to add the Motion-Blur effect in a compositing software:

  1. The ‘motionvector’ AOV must be added to the AOVs list in the AOVs tab of the Render Settings window.
  2. Motion-Blur must be enabled in the Motion-Blur part of the Arnold Renderer tab in the Render Settings window.
    * Otherwise motion vectors will not be calculated.
  3. In the Diagnostics tab of the Render Settings window, under Feature Overrides, check ‘Ignore Motion Blur’, so Motion-Blur will not be rendered.

Rendering an animation in Maya and Arnold

Maya 2018 | Arnold 5

  1. Set a Project Folder or Image output path.
  2. In the Render Settings > Common tab, set the output file format, and in Metadata, set Frame/Animation ext. select an option that isn’t Single Frame.
    * This will make the Frame Range settings available.
  3. Set the Frame Range.
  4. Set the Maya UI to Rendering and choose Render > Render Sequence.



Displacement in V-Ray for Maya

Maya 2018 | V-Ray 3.6

Basic Displacement through the shader:

1) Connect a displacement map to the Displacement Shader input of the Shading Group Node.

2) Multiply the value to set the displacement amount.

3) Control Displacement Settings globally through VRay Render Settings:
Edge Length:
The minimum size in pixels for new created edges.
Lower values will create more detailed geometry but cost more memory.



Per Object Displacement with more controls:

1) Add a VRay Displacement node to the object (See images).

2) Connect Displacement Map

3) For more control, and Local displacement quality settings,
In the Attributes Editor, Add VRay Displacement Control and VRay Subdivision and Displacement Quality attributes to the object (See images).



V-Ray for Maya Matte / Ray Visibility

Maya 2018 | V-Ray 3.6

Basic object render visibility can be set through Maya’s Render ‘Stats settings’ in the object shape node.

For more control and Matte Object / Shadow catching options, add VRay Object Properties to the Object (See Example)

To Create a Shadow Catcher:

1) Add VRay Object Properties to the objects (see image)

2) In the VRay Object Properties attributes, check ‘Matte Object’

3) Check Shadws


Shadow Catcher Notes:

* Artifacts in shadows while using Light Cache GI (no problem with Brute Force GI)

* When using a Dome Light, the Dome light Back ground will not show through the Matte Object but the Environment background to solve that connect the Dome light texture also to the VRay Enviroment Override.

* In order for ‘Affect Alpha’ to work and produce transparent image, ‘Alpha Contribution’ must be set to -1.



Matte Shadow and Ray Visibility can also be set through shaders, by using a VRayMtlWrapper:


And also by using a VRayRaySwitch texture:
