Arnold is an advanced Monte Carlo ray tracing renderer built for the demands of feature-length animation and visual effects rendering, largely used to create movies and video games.
Arnold must be downloaded and installed manually. In this example we will download the Arnold software, move it to the /tmp directory where it will be accessible within the container, create a sandbox container that we can interact with it in writable mode, and manually install Arnold. This is not the standard best-practices workflow for creating Singularity containers, but may be necessary in some cases where non-interactive installations are the only method available.
In order to download Arnold, you will need to sign in or create an account with AutoDesk:

From within the container, copy (or move) the installer to the /tmp directory where it will be accessible inside the container at runtime.
