The Rhinoceros Material Editor.
The Rhinoceros Material Editor.


This section describes how to create and manipulate Arion materials in RHINO LIVE. For a comprehensive technical description of how the Arion material system works, or what each particular parameter does, please refer to this area of the Knowledge Base.



It is strongly recommended to enable the Tree View mode in the Rhinoceros Material Editor. The Tree View provides a clear representation of the internal structure of RandomControl LIVE materials, and also a straighforward way to navigate through the material root, the BSDF/Emitter layers, and the mapped slots.

The Arion material system translates to Rhinoceros in the following way:

Entity in ArionEquivalent in RHINO LIVE
Material rootRandomControl LIVE Material material content node.
BSDF layerRandomControl LIVE BSDF Layer material content node.
Emitter layerRandomControl LIVE Emitter Layer material content node.
Texture mapEither a native bitmap or a RandomControl LIVE Bitmap texture content node.
Photometric profileRandomControl LIVE Photometric texture content node.

To create a RHINO LIVE material, simply create a material from the Rhinoceros Material Editor, and select the RandomControl LIVE Material type. This is the material root, where it is possible to add BSDF or Emitter layers.

By default, RHINO LIVE materials are created without any layers, and render as default mid-gray lambertians.

In order to add a new layer, press one of the + buttons in the material root node. A dialog will pop up where it is possible to add a BSDF or Emitter child layer. The Material Editor will then display the parameters of the newly created layer, while the Tree View will display the layer as a child to the material root.

Many properties in the RHINO LIVE content nodes can be texture-mapped. In order to apply a bitmap to one of these mappable properties, use the little square button button to the right of the property. A dialog will pop up where it is possible to select a bitmap or a photometric profile. Similarly to the case of material layers, the Tree View will display the newly created texture node as a child to the content node it was created from.

The material root node features some other buttons with the following functionality:

ButtonWhat it does
Load from .rcmReplaces the material node by the contents of an existing .rcm file.
Saves as .rcmSaves the contents of the material node to a .rcm file.
Open LibraryOpens a .rcm thumbnail browser from where it is possible to load a material.
PreviewForces a refresh of the material preview thumbnail.



Material previews may take a few seconds to compute. For this reason, automatic re-generation of material thumbnails is disabled.
