VRam usage on startup at 16gb

Hello,

Looking for some direction on handling these assets that load on project startup. The project has data/environments in it. Opening the project without opening any levels creates a 16/24gb dedicated gpu memory overhead.

Render Resource Viewer lists 8 high res hdri images with ~1gb each as loaded. How can I change their loading into vram so that they only load when I access them or open a level that references them?

To test, I duplicated a few of the hdrs and added them to a new level. On restart, those new hdrs are not loaded into memory and load into memory only when that level is open, so not sure what is going on with the other 8 hdrs.

Thoughts?

Thank you!
