Enhancements
  • Pick materials in Render View: You can use Ctrl+LMB in the Render View to pop up a panel with the material that shaded the pixel that was clicked. (htoa#119)
  • Update TX Textures menu entry: The Arnold menu now contains a simple function to update all the TX textures of the scene. (htoa#730)
  • Update TX Textures Python command: An equivalent command to update all TX textures of the scene is also available: htoa.material.updateAllTx(force=False) (htoa#730)
Fixes
  • For custom stereocam rigs, fallback to the camera name if the subcamtag parameter does not exist on the sub-cameras (htoa#654)
  • Fixed disabling TX auto-generation on the ROP (htoa#730)
  • More robust checking if a TX texture needs updating (htoa#730)
  • Fixed confusing "icp: Unable to open..." error messages (htoa#730)
  • Crash if there are more than 100 UDIM rows (core#5002)
Incompatible changes
  • Coinciding vertex attributes merging is now enabled by default, to avoid the many support requests about UV discontinuities when subdividing. This incurs a slight translation time overhead but uses up to 4x less memory to store vertex attributes. Also, the Merge Vertex Indices option is now located in Subdivision tab. (htoa#729)
