Version 1.2.799 is now available for Windows that includes Spout 2 support.
Spout is a WIndows based open-source technology for sharing the video output from one application to another.
Painting With Light now supports sending its output via Spout. You don’t need to enable this, it will happen automatically.
A future version will enable receiving textures via Spout so you will be able to use Painting With Light’s video mapping tools with live output from other applications.
See the Spout website to see which applications are supported.
