HtoA 2.1.2

8 August 2017

This is a feature release, bringing continued improvement to IPR rendering.  We now support adding, removing and re-wiring of shaders during IPR renders in the VOP shading network, including connections to hanging shader nodes that were unconnected at translation time. This now includes changing the final connection to the Material Output nodes' surface and volume slots in the VOP network (as long as a shader was connected during translation).  

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

This release uses Arnold and OpenVDB 4.0.0.
