Usage
bpx prop list <file.uasset> --export <n>
bpx prop set <file.uasset> --export <n> --path <dot.path> --value '<json>' [--dry-run] [--backup]
bpx prop add <file.uasset> --export <n> --spec '<json>' [--dry-run] [--backup]
bpx prop remove <file.uasset> --export <n> --path <dot.path> [--dry-run] [--backup]
Behavior
list: decodes properties for one export and includes warnings.set: updates an existing property value at --path.add: appends a new top-level property from --spec JSON.remove: removes a property at --path.- Write subcommands report old/new values, size deltas, and changed-byte status.
[!CAUTION] This command includes write-capable operations. Confirm intent and run
--dry-runfirst.
Command Matrix
| Command | Use when | Notable defaults |
|---|---|---|
list | decodes properties for one export and includes warnings. | Read-only path; safe for discovery. |
set | updates an existing property value at --path. | Run --dry-run first and use --backup for real writes. |
add | appends a new top-level property from --spec JSON. | Run --dry-run first and use --backup for real writes. |
remove | removes a property at --path. | Run --dry-run first and use --backup for real writes. |
Code-Aligned Caveats
- Write paths mutate one export only; invalid dot paths fail explicitly.
- Prefer
prop listimmediately beforeprop set/add/removeto avoid stale assumptions.
