This is a bugfix release, adding support for subdivision soft creases and a few other enhancements.

  1. Get the install files on  Solid Angle Downloads.
  2. Follow these installation instructions.

This release uses Arnold and OpenVDB 2.3.0.

Binaries available for the following Houdini or Houdini FX production builds:

  • 13.0.582
  • 13.0.547
  • 13.0.509

and for the following platforms:

  • Linux x86_64 (gcc4.4)
  • Windows 7 x64 (vc11)
  • Mac OS X 10.8+

 Please note that Houdini Apprentice and Houdini Indie do not support third party renderers and thus cannot run HtoA.

  • OpenSubdiv compatible edge and vertex soft creases. You can control the sharpness with the Houdini Crease SOP or the creaseweight and creaseweight_point vertex and point attributes (#463)

  • New ARNOLD_PROCEDURAL_PATH environment variable that can optionally contain a list of directories to scan for procedurals (#479)

  • Light group controls on Arnold lights for the popular alSurface shader (#482)
  • Refactored the space_transform shader and included tangent space support and other enhancements (#392)
  • Fixed NaNs in volume_collector, volume_sample_float and volume_sample_rgb in optimized builds (#374) 

  • Fixed regression that disabled automatic node id generation for shapes (#477)

  • Emulate ROP initialization scripts, any scripts/out/arnold.py script found in the HOUDINI_PATH will now be properly executed. Like other initialization scripts, the created ROP's hou.Node object is found in kwargs['node']. Unlike the other ROP initialization scripts, you don't need to worry about recreating the render properties (#480).
  • Clustered volume bounding boxes are now correctly displayed (#475)

  • No labels
