Octane doesn't support loading sIBL environments directly, but via a script you can set up a common use case: setting up a HDR environment and sun light.
This script will set up the sun position and environment texture, but it has limitations:
- Only files containing a Sun Light are loaded.
- Only environments using lon-lat mapping are loaded, since the other types can't be rendered correctly in Octane.
- The sun power in Octane can't be set easily to a given number, as required to load sIBL files. This means you have to tweak the power of the environment texture after loading to balance the sun and environment powers.
- There is currently no easy way to rotate such an environment. The script will set up the environment taking the north offset into account.

To use, select the render target to render or the environment node. The environment must be set to a daylight environment (replacing a node is at the moment not exposed in the Lua API).
