DSMapStudio Params Not Showing: Troubleshooting
The project opened, the Param Editor is on screen, and there's nothing useful in it. Before touching anything: clear the row search box. The single most common "no params" report is a leftover filter from earlier, and it costs one second to rule out. If that isn't it, "params not showing" is really two unrelated problems — the editor is empty (no data loaded) or the rows are there but nameless (1000000 instead of a weapon name). Empty is a file/project problem; nameless is a Paramdex problem. They look identical and fix differently, so identify which one you have first.
Which problem is it?
- Empty — the param-table list is blank, or a table opens with zero rows. DSMapStudio couldn't read the game's params at all → file/project.
- Nameless — rows exist with IDs and values, but they're bare numbers and name searches return nothing. The data loaded; the names didn't → Paramdex.
Symptom-to-fix
| What you see | Cause | Fix |
|---|---|---|
| Nothing changed but rows vanished | Leftover term in the search box | Clear the row search (and the param-list search) |
| Param list completely blank | Pointed at packed files, not unpacked | Unpack with UXM, recreate the project |
| Tables open but every value looks wrong | Wrong Game Type | Recreate with the correct Game Type |
| Rows show as bare IDs, no names | Paramdex missing/outdated/wrong Game Type | Row names & Paramdex |
| Some new rows unnamed, rest fine | Patch added rows Paramdex doesn't cover yet | Update to the latest DSMapStudio build |
Empty Param Editor
No data means DSMapStudio couldn't read the tables inside regulation.bin. Two reliable causes, both fixed by recreating the project correctly:
- You pointed at packed files. DSMapStudio reads UXM-unpacked files (UDSFM for Dark Souls: PTDE), never the packed Steam install. Point the Game Directory at the packed folder and the project still creates — it just opens to an empty editor. Unpack first, then recreate against the unpacked folder.
- Wrong Game Type. A mismatch loads nothing or shows garbage. Recreate with the exact Game Type selected.
Full procedure: first project setup. Empty across every param is almost always one of these two.
Rows show but names are missing
Rows and values present, but labeled with raw IDs and name search finds nothing → the params loaded and only the Paramdex name data isn't being applied. Causes: wrong Game Type (names are per-game), an outdated Paramdex that doesn't yet cover a new patch's rows, or a build missing its bundled Paramdex. Names are their own subsystem, so the full fix lives on row names and Paramdex — short version: match the Game Type and run the latest build, which ships current Paramdex.
The one people stare past — a leftover search filter
Worth repeating because it eats the most time: the Param Editor filters rows live as you type. Search earlier for modified, an ID, or a name and forget to clear it, and the table hides every row that doesn't match — pixel-identical to "no params," but the data is fine. The param-list search at the top does the same to whole tables. Clear both boxes before assuming anything is broken.
In order
- Clear the row search and the param-list search — rule out the trivial cause.
- Empty or nameless? Decide which problem you have.
- If empty: confirm the game is UXM-unpacked and the Game Type matches, recreate against the unpacked folder.
- If nameless: confirm the Game Type, run the current build — row names.
- Verify: open
EquipParamWeapon; named rows with sensible values means it's fixed.
Back in business once params load — head to the Param Editor hub. Still empty after unpacking and matching the Game Type? The troubleshooting hub covers the wider set. Rejected before the project even opened, with "invalid game executable"? That's a path problem — invalid game executable.
