Hair and Fur


The Modo plugin can automatically convert Modo Render Curves to Octane Hair geometry. The Modo Fur MaterialThe representation of the surface or volume properties of an object. can also be baked to curves, or rendered directly by using the Modo Render Cache.



Modo Render Curves

Modo Render Curves can be converted to Octane Hair geometry by using the following steps:

  1. On a Mesh that contains curves, enable Mesh > Curve > Render Curves.
  2. Use the Curve Radius to set the Octane hair strand radius.
  3. The Curve Radius Gradient start and end values can be used to adjust the Octane hair strand radius along its length. Start and End properties are not supported.
  4. Right click the Mesh > Shade > Create Item Mask, then add an Override to this mask.


NOTE: Hair geometry generated from Render Curves will have W Coordinates which can be used for texturing. See the W Coordinate texture for details.

NOTE: When using Render Curves, if the mesh contains curves and non-curve geometry, Octane will only render the curves. Non-curve geometry will be discarded.


Modo Fur Material

The Modo Fur Material can be rendered by baking the curves or using the Modo Render Cache.


To bake the Fur Material to curves:

  1. Add a Fur Material to a material in the Shader Tree.
  2. Bake the fur to curves using Modo > Geometry > Bake Geometry Cache.
  3. Follow the previous steps for using render curves.


To render the Fur Material using the Modo Render Cache:

  1. Enable Kernel > Settings > Use Modo Render Cache.
  2. Add a Fur Material to a material in the Shader Tree.
  3. Set the Geometry & Shading > Type to Strips. The Cylinders option is not supported.
