This Scene file showcases how to create the sparkler video and splash screen image used to launch Houdini 19. The file contains the lopnet used for rendering, as well as a topnet to generate the entire shot at once. This is necessary as the shot is built up of many caching steps needed to be generated in the right order. To do that, jump into the topnet1 network and cook the karma_sparks top node.
NOTE: The scene file requires the latest Sidefx Labs version to be installed, as it uses Labs version of the File Cache and Karma lop nodes, as well as the ACES OCIO config.
