Functional Changes

  • Face Lighting and Patterns Lighting appears correct when parts of a face are deleted. When HC_Set_Driver_Options(“window opacity=0”) is set the face pattern applied is also rendered.
  • Show_Owner_By_Key Show_Owner_By_Key returns with correct key in the C# interface.
  • Windows SDK Support All Windows platform sandboxes have been updated to Windows SDK 10.0.22621.3233.
