  • Substance : Fix rare semaphore-related error message.
  • Substance : Fix rare hangs/crashes when building user projects.
  • Substance : Decrease memory footprint after initial scene load
  • Substance : Fixed potential crash when baking ProceduralTextures to compressed formats
  • Webplugin : Fixed a crash where decompression threads were still working, even though the plugin was being closed.
  • Windows Phone 8/ Windows Store Apps : Fixed small memory leak in animation system.
