You can start the interactive engine application from a command-line prompt, and provide parameters on the command line to trigger lightmap baking.

Note: Non-interactive baking is the default baking mode when you launch a baking session from the command line. See Baking with the built-in light baker.

1. Open a command prompt and change to the following directory:

   `C:\Program Files\Autodesk\ Interactive\<version>\engine\win64\dev`

2. Enter the following command:

   interactive_win64_dev.exe --toolchain "C:\Program Files\Autodesk\ Interactive\<version>" --ini core/stingray_renderer/light_baker/standalone/light_baker --project-root <absolute path of the project's source data> --level <path of the level to bake, relative to the project root> --viewport-provider

• --toolchain should point to the absolute path of your binaries directory. Most users will find this under C:\Program Files\Autodesk\ Interactive\<version>.

• --project-root should point to the absolute path of your project's source data.

  For example, C:\Interactive_Projects\New_Project

• --level should point to the path of the level you want to bake.

  For example, level content/levels/basic
