Fixing up few last instances of broken alpha due to the asset variant system. A few more tweaks too. Updates Android / Oculus Quest builds to the latest as well!
- Added a mechanism for updating asset metadata
- Simplified object hierarchy for imported images - they are now represented by a single object, rather than adding a child.
-- This also fixes issue with thumbnail not using the actual texture when saving to inventory (reported by Iforgotwhosorry ;_; )
- Scheduled new metadata version to fix incorrectly generated metadata with invalid alpha information. This should help fix more cases of textures having black background instead of transparent ones (give it a load or two, for the old data to be purged/recomputed)
- Added auto-update for radius for the old SnapTarget components (this fixes the old ones before the change which made the radius in local space rather than global)
