Size map reporting oddly large MBs?

I’ve got a nanite mesh that is reporting a much larger memory size than disk size, and both of these are significantly higher than what the asset viewer reports. 750MB memory, 360 Disk and asset viewer is 158/40 (nanite). I’ve a number of other meshes with similair polycounts and they report much saner numbers (Avg disk size of 350MB and Mem size of 3MB / about 40MB nanite reported in asset viewer) All are nanite enabled. Anyone have a clue what is going on?

Unsure of the source of this, possibly something I did, but couldn’t find anything obvious.

Resolved by exporting and re-importing as a new mesh (disabled nanite before doing so) - now reports similair to others.

Anyhow, just a reminder to keep an eye on size maps.
