The Elias 4 plugin can also import the Elias 3 project files (.mepro). Elias 4 has specific nodes to control the Elias 3 project either from the mixer or from a patch. Read more about the nodes in the Elias 4 section earlier in this documentation.
The Elias 3 project will be played from an Elias 4 project by adding a music output node in a chain connecting to the master output or directly to the master output, so this means that you will need to install the Elisa 4 studio to create an Elias 4 project if you don’t already have an Elias 4 project ready and set up that you can load to the plugin.
Elias 4 will not be directly aware of the Elias 3 project, so nodes that perform “set level”-, “play stinger”- or, “play action preset”-events, etc. will do those actions to the currently playing Elias 3 in Unreal. As long as names are matching and the content is there, the music will react to the actions from Elias 4.
