Object properties

The object settings tab is context-sensitive and based on the current selection. When you select a Rhino object, the window displays its settings.


  • Name: Change the name of the selected object, group or block
  • Enable: Makes the object invisible. It will also not be visible in reflections / camera and will not cast shadows
  • Visible to camera: Hides the object from the camera. It will still be visible in reflections and will cast shadows
  • Visible in refl/refr: The object will not be visible in reflections and refractions
  • Shadows: Defines whether the object will cast shadows or not.
  • Mask Index: Used along with the Mask render channel. Objects with a value greater than zero, will make Thea for Rhino to generate a separate channel for them when Mask channel is enabled.
  • Assign Container: Assigns the selected material as a container for the object

General properties


  • Subdivision: Subdivides the surface in render time. There are two methods to choose from. Planar or Charles-Loop
    • Level: Defines how many times the surface will be subdivided
  • Weld Vertices: Welds the vertices of the selected object

Subdividing a surface can help displacement to give a better result. This is especially useful for flat surfaces having a few triangles.

Geometry properties


  • Material: Select the material that will be used to the back face of the surface

Back face material properties


  • Bevel: Enable or disable beveled edges
  • Edge ramp: Controls the angle and radius properties of the Edge Ramp procedural
  • Angle (degrees): This value allows the user to limit the effect of beveled edges to corners with an angle greater than the one defined here
  • Radius (cm): Defines the radius of the beveled edges in centimeters. When the material of the object uses the Edge Ramp procedural, the same value will be used for the width of the edges

Beveled edges properties


Some parameters, rather than being constants, can have a range of values. This can be accomplished in two ways:

  1. By clicking on the icon in between the two values to enable min/max or
  2. Load a greyscale image that will be used as a weight. Black means 0% and white 100% of the defined value.
  • Segments: Number of segments for each strand
  • Density (strands/cm2): The amount of strands in a specific area
  • Length: The total length of the stand
  • Thickness: The thickness of the strand
  • Fuzziness (%): Makes the strands curly
  • Top thickness (%): Increases the thickness of the strands upper part
  • Bending (%): Causes the strands to bend
  • Direction: The direction of the strands
  • Direction axis: Controls the orientation per axis
  • Sampling method: Random, Quasi-random
  • Material: Defines the material of the strands
  • Gravity: Strands are pulled down in the z-axis

Fur properties


  • Export as Thea proxy: Converts the selected object, group or block to a Thea proxy model
