HDRIs do not appear in exported Presentations

Reported in SF [Link Removed]

HDRI environments are not appearing in exported Presentations. Occurs for both Local and Cloud exports and across all HDRI types.

Thumbnails for Cloud Presentations will properly display the HDRI but will not display the HDRI once loaded.

1. Open any TM scene
2. Add any HDRI backdrop or sky to the scene
3. Export a Presentation either locally or to the Cloud

Result: The HDRI will not be visible in the loaded Presentation
