Hi, If you download and install Pixel Bender on OSX and install it (as per the README), the default path it installs to is: /Applications/Utilities/Adobe Utilities-CS5.localized/Pixel Bender Toolkit 2
It's contains spaces which may be an issue. I currently get this when trying to build: Execute failed: java.io.IOException: Cannot run program "${env.PIXELBENDER_HOME}/pbutil" Thanks, Justin
