Features

  • #1384 IPR for the usd procedural update on frame change.
  • #1380 Add the auto_instancing toggle to arnold_procedural OTL to enable auto-instancing of duplicate Arnold procedural nodes created when using .ass files.
  • #1336 Add the string_replace operator which matches and replaces parts of string parameters, optionally depending on the OS Arnold is running on.
  • #1369 Adding tilt/shift options for perspective render camera to control lens tilt angles with respect to the projection plane. This is useful in architectural renderings to compensate perspective transformation for vertical lines.
