OctaneRender® supports a subset of the OSL standard, plus a few extensions to use features specific to OctaneRender.

 

Unsupported Features

  • Point cloud functions.
  • Dictionary lookup functions.
  • Message passing is generally not supported, except for the built-ins listed under "Octane extensions" (see below).
  • Derivatives.
  • trace(). For AO like effects, you can add a color input and connect the input pin to a Dirt node.
  • Material shaders and closure variables.
  • wavelength color(). Use _gaussian() instead.
  • struct variable types.
  • The global variables Ps and dPdt.

 

Partially-Supported Features

  • noise() doesn't support 4D noise, and doesn't support the Simplex and Gabor noise types.
  • The global variable time always has a value between 0 and 1, and represents the time within a subframe.
  • getmessage() and gettextureinfo() must have string literals as attribute names.
