CreateGeometry job failed with error code: 7

Hello. Trying to upgrade a project and enabling GI. Converted all mats to standard. As I turned on iterative workflow, it’s stuck on “Enlighten - Geometry (3)” at what looks like 95%. Console getting spammed with:

‘CreateGeometry’ job failed with error code: 7 (‘Failed to pack Geometry.’).

Any clues?

No, no clues I’m afraid. It’s not because of too high res, as we clamp it if something wouldn’t fit into a system…
