  • Environment Light COMP / PBR MAT - Fixed recent bug where environment lights would not work if there are more environment lights than regular lights in a scene.
  • List COMP - Fixed growing list of dragItems when re-entering list area.
  • Table COMP - Now Children page parameters on any parent properly apply Fit and Scale parameters to a Table COMP.
  • Line MAT - Fixed 'Start Caps Pullback' so it pulls back all line segments, not just the start segment.
  • Phong MAT / PBR MAT - Fixed compile error when using 3D textures or 2D texture arrays.

  • MIDI Out CHOP - Added 'events_sent' to Info CHOP for diagnostic purposes.
  • Script CHOP - Fixed crash when using ScriptCHOP.copyNumpyArray on zero-sized numpy array.
  • Touch Out CHOP - Added toggle to disable constantly re-sending channel names for UDP based connections.
  • Touch In CHOP - Reworked queuing a bit to improve behaviors.
  • FOlder DAT - Fix pattern parsing crash and add error to Folder DAT if parsing issue found. Fixes issue of setting Folder DAT's 'Extensions' parameter to a list.
