Why don't my Data Asset multi-edit changes save?

Default inspector commits per-asset and changing selection drops uncommitted changes. Use Property Matrix Editor (right-click on multi-select → Bulk Edit via Property Matrix) which saves cleanly.

Find/replace in Data Tables?

Data Table editor's spreadsheet allows column edits. For Data Assets, Property Matrix is the equivalent.

Q: Where is Property Matrix?

Multi-select Data Assets in Content Browser, right-click → Asset Actions → Bulk Edit via Property Matrix. A grid view opens; edits commit on focus change.

Quick answer: Multi-select → right-click → Bulk Edit via Property Matrix. Edits commit cleanly per cell.

200 weapon Data Assets all need DamageMultiplier = 1.5. Inspector with multi-select shows shared properties; edits don’t save when you switch.

The Fix

Content Browser:
  Filter: Data Asset (WeaponData)
  Select all (Ctrl-A)
  Right-click → Asset Actions → Bulk Edit via Property Matrix
    Spreadsheet view opens
    Edit DamageMultiplier column → commits per row
  Save All

Property Matrix is built for the bulk-edit case. Inspector is single-asset oriented; multi-select shows shared values but doesn’t persist edits across selection changes.

Verifying

Reopen any of the assets: DamageMultiplier shows new value. Without Matrix: only the last-edited asset saved.
