A target config is an object that configures the target machine that handles data. You can specify default values, mainly encoding settings at build time.
When creating a project, a PC target is prepared.
Also, the initial values of the encoding settings and streaming settings for each Material are set to "default".
Therefore, the setting value of the config target will be effective.
For PC targets, you can set the speaker settings for PC preview by clicking criatom_tools_atomcraft_preview_pc_speaker in "Show Speaker Settings".
By switching targets from the "Build Target" menu in the upper right corner of the tool, some of the display, newly added items, and editable items will change.
