How to mod this game:

 

Unpacking files:

Quote

 

  • Install python
  • Download extract_pac.py (right click, save as) 
  • Put extract_pac.py in your {Sky 1st}/pac/steam folder
  • Drag the pac file you are interested in onto extract.py (OR you can just double-click extract_pac.py and extract everything at once).
    • Most mods will require unpacking asset_common_model.pac, asset_common_model_info.pac and image.pac!

  • It will unpack a folder.  Move that folder to the base folder (the one with sora_1st.exe).

 

Spoiler

2025-08-2122_38_45-steam-FileExplorer.png.03b04dd2bd50b9ea1326a82d78ee6817.png

 

  • Rename or delete the .pac file you unpacked.

  • Now the game will use the loose files!  You can see what my root folder looks like with the asset folder.

  • (OPTIONAL) You can unpack everything and delete all the .pac files if you want, I can confirm it works.  Be sure to move all the folders AND the multilang_resource_list.json file into the base folder.

Creating custom tables / combining mods that require custom tables:

Quote

 

  • Unpack your table files using the above instructions.  I unpacked "table_en" because I am playing in English.
  • Create an empty folder, and put t_costume.tbl, t_dlc.tbl, t_item.tbl, t_name.tbl and t_shop.tbl in this folder along with all of your .kurodlc.json files and kurodlc_make_tbls.exe.

 

Spoiler

NOTE: Do not simply run kurodlc_make_tbls.exe inside your table_en folder or the game will crash upon loading!  The tool is meant to mod a variety of games and will attempt to rewrite tables it should not be rewriting because it cannot tell the difference between Daybreak and Sky tables.  Be sure to make a dedicated folder just to run this tool!

 

  • Run kurodlc_make_tbls.exe and it will write new tables with all of your .kurodlc.json data incorporated into the tables.  Copy t_costume.tbl, t_dlc.tbl, t_item.tbl and t_shop.tbl back into table_en (or whatever language folder you are using).

  • Load up the game and enjoy!

 

 

For modders who want to make a mod with custom equippable items:

Quote

 

Per recommendation from @fakecheng, make a folder for searching IDs / combining tables (folder1), and a separate folder for making your final tables to include with a mod (folder2) -- you do not want entries from other mods inside your mod table!

 

  1. Download my Kuro DLC tool here: https://github.com/eArmada8/kuro_dlc_tool/releases and run the included install_python_modules.bat.
     
  2. Extract the original t_costume.tbl, t_dlc.tbl, t_item.tbl, t_name.tbl, and t_shop.tbl from table_en.pac using sky_extract_pac.py (see above) and put all 5 files in both folders.
     
  3. Put any existing .kurodlc.json files you want to search with in folder1.
     
  4. Put kurodlc_find_item_id.py, kurodlc_find_dlc_id.py, kurodlc_lib.py, and kurodlc_schema.json in folder1.  Use kurodlc_find_item_id.py and kurodlc_find_dlc_id.py to find available item IDs and DLC IDs.  (Yes, the way my tool works, you do need DLC IDs even though we will not be using the DLC function.  This is NOT optional.)  You need one available item ID for each costume, and one DLC ID for the entire set.
     
  5. Put your mdl files, kurodlc_make_json_from_mdls.py, kurodlc_make_tbls.py, kurodlc_lib.py, kurodlc_schema.json in folder2.
     
  6. Run kurodlc_make_json_from_mdls.py.  It will ask you questions about the dlc pack (dlc name, description, etc.) then individually about each mdl file (costume name, costume description, etc.).  It will generate an  .mdl.json file for each mdl file, as well as a dlc.json file - these are used on subsequent runs of the tool so that you do not need to repetitively type in answers.  Just edit the files in Notepad.  After generating dlc.json and the .mdl.json files, it will generate the .kurodlc.json file.  *Please include this file with your mod!*
     
  7. Run kurodlc_make_tbls.py, and it will make the t_costume.tbl, t_dlc.tbl, t_item.tbl, and t_shop.tbl.
     
  8. Make a folder for your mods inside folder2, name it whatever you want, for example "my_awesome_mod".  In the subsequent steps, I will call this folder {mod folder}.
     
  9. Make a folder {mod folder}/asset/common/model and put your .mdl files in there.
     
  10. Make a folder {mod folder}/asset/common/model_info and put your model .json files in there.  (These are the dynamic bone descriptions etc.  These are NOT the .mdl.json files generated by my tool!)
     
  11. Make a folder {mod folder}/asset/dx11/image and put your .dds files in there.
     
  12. Make a folder {mod folder}/table_en and put t_costume.tbl, t_dlc.tbl, t_item.tbl, and t_shop.tbl in there.
     
  13. Copy the contents of {mod folder} into your Trails in the Sky folder to use.

 

Enjoy your mod!  Be sure to put your items for sale in a store or you will not have access to them.  It is possible to make a DLC mod, but DLCs must be tied to the Steam API so going this route is going to create serious headaches for players so I do not recommend it.

 

For mod distribution, please include the .kurodlc.json file with your mod files.

Free camera for Trails in the Sky 1st Chapter!  Upload will be replaced when the final game comes out (for GungHo release, CLE version is unlikely to ever be updated).

 

Gungho: - Upload replaced 1/8/26 for game update to 1.06.2

 

Sky 1st Free Camera for v1.06.2.CT.zip

 

CLE: (Updated by @fakecheng) - Upload replaced 1/9/26 for game update to 1.06.3

 

Sky 1st CLE Free Camera_rev8.zip

 

How to use:

Quote

 

This script is used with Cheat Engine (CE).  Instructions on how to install CE and load the table here.

 

Feature List:

  • Force Pause Animation - F5 to turn on, F6 to turn off - this completely pauses the game!  Check the box to enable before using.
  • Hide Interface - F7 to toggle. Everything disappears - interface, minimap, dialogue, menus, overlays, letterboxing, everything.
  • Control camera distance (zoom) - F4 to toggle. Press Home to zoom in, End to zoom out.  Will remember your custom zoom value prior to cutscenes and restore the value after, IF you do not adjust the zoom during the cutscene itself.
  • Free camera - press 0 to activate. See instructions below on how to navigate.
  • Set Camera Min Z to Floor: There is a function that stops the camera from going any lower than waist-height. This changes the limit to just above the floor. For the best experience, also turn on No Clip.
  • No Clip - Objects will stop disappearing when they get too close to the camera.

 

Free Camera Controls:

 

Hotkey : Num 0 (Toggle On/Off)

 

After activating the script player can use the following hotkeys:
W : Forward
S : Backward
A : Left
D : Right
R : Up
F : Down

 

Mouse control for tilt/pan!  (You can turn mouse support on and off with page up / page down keys while the script is active.)
I : Tilt Up
K : Tilt Down
L : Pan Right
J: Pan Left

 

F1 : Decrease Camera Speed (Press and Hold)
F2 : Double Camera Speed (Press and Hold)
F3 : Quadruple Camera Speed (Press and Hold)

 

 

Enjoy!

 

Here are all my other free camera scripts:  Trails of Cold Steel (CS) 1, CS2, CS3, Trails into Reverie, Trails through Daybreak, Trails through Daybreak II, Hajimari no Kiseki, Kuro no Kiseki, Kuro no Kiseki 2, Kai no Kiseki, Tokyo Xanadu eX+, Ys VIII: Lacrimosa of Dana, Atelier Ryza, Atelier Ryza 2.  I also made a MinZ (*cough* upskirt) script for CS4.

Here is a cheat table for Trails in the Sky 1st Chapter that lets you override purchases - buy anything you want for the price of a tear balm!

 

Gungho version: - Upload replaced 1/8/26 for game update to 1.06.2

 

Sky 1st Purchase Override for v1.06.2.CT.zip

 

CLE version by @fakecheng: - Upload replaced 1/9/26 for game update to 1.06.3

 

Sky 1st CLE Purchase Override_rev7.zip

 

How to use:  (Note - screenshots are from Trails through Daybreak because I am too lazy to take new ones)

Quote

 

Open the table in Cheat Engine, and attach to Sky 1st.  (Exactly the same process as my free camera)

 

Check "Override Purchase Item."

9563433_2022-08-1318_06_16-Window.png.6d1a1ed573b64d4067187cebec164fc1.png

 

Double-click the current item in Item Override (default is Tear Balm).

 

Spoiler

Pick the item you want from the drop-down menu, then press Ok.

 

Spoiler

739320480_2022-08-1318_09_29-Clipboard.png.5090518556b7878dafc0cbda0a28ab2e.png

 

Buy something in the game, it does not matter what it is.

You now have the item you desired!  Be sure to uncheck the box in cheat engine or you cannot buy anything else.

NOTE: Turn off the cheat after purchasing. The game engine uses the same instruction to buy items and unequip items! (Actually you can use this cheat to get items by unequipping if you are not near a store but of course you will lose what you unequip.)

 

Enjoy!

Thank you for creating this thread so quickly! I was on the fence, but now I'm definitely getting it!

I truly appreciate your prompt creation of this thread.👏

I had been undecided, but this has helped me make up my mind.


As you may know, I'm still relatively new to editing MDL files.😅

With that in mind, I was wondering if the method is the same as it was in Ys X?

 

Honestly I have not tried to make any mods yet.  At least in theory, yes, it is exactly the same as modding Ys X.  🙂

 

I will probably not try to mod it until the full game comes out.  The demo is missing many files!

Honestly I'm just curious if they still have well modeled panties. The dresses are too long in the demo for me to see up. As long as Falcom hasn't resorted to doing to the black voids of death I'll be happy.

I took a look through all the folders but I can't seem to find the english text files or the like. Are those all in the tbl files? Script_en seemed more like actual game scripting then the english text.

Dialogue etc are inside the scena files (script_en).

I put up the free camera script, go nuts!  Download here.

 

Also, here is a list of all the characters and what the model files are.  Most of the actual files are missing from the demo.

Thanks. Managed to find it and poke around the script, and wouldn't you know it's surprisingly easy to change text. Went and replaced the intro text with the Xseed TL just to see if it was possible.

Good news, Falcom hasn't fallen yet.

 

Edit: most of the female NPCs in town simply have black blobs under their dresses, which kind of makes sense as their dresses go all the way to their ankles anway. Only important npcs seem to have panties. Aina has them but I suck at getting shots with the free camera mod and it's tough because her dress is pretty long too. Still, got the info I wanted.

Estelle's underwear mod (testing mod).

 

aefasfasfas.thumb.jpg.facf697f71ef50e6ab1b89535042e2b9.jpg

 

I only made this mod to test whether the modding process for Trails in the Sky is the same as for Kai no Kiseki. I directly transplanted Agnes's body from Kai underwear mod onto Estelle, so the skin tone will be different from Estelle's original.

 

I will remake this mod when Trails in the Sky the 1st is officially released.

 

Estelle_UDWtest.7z

 

Installation:

Follow this tutorial to unpack 'asset_common_model.pac' and 'image.pac'.

Place the 'asset' folder from the mod to game base folder.

Enjoy!

I just tested it on the CLE release. Can confirm Hide HUD is the only thing that works for me 😂.

When I press Num 0, the script just gives me a 'beep' and nothing happens.

God Damn it why did Falcon have to give publishing rights to multiple companies.

I have to press it twice to get it to work. There's two different beeps. And the second one is what lets me move around freely.

Are you playing the GungHo (English) version or the CLE (Chinese) version? I tried again on the CLE version, but it's still not working.

Just a reminder in case anything happens, ayakamods tolerates all kinds of mods. So might consider uploading there as well.

How is it installed? Do I have to copy the files to a folder or inside the .PAC files?

 

All models mods will probably be installed the same way, follow the instructions on the first page on extracting the asset_common_model.pac and disable/delete them, move the asset folder to the root folder with the exe, then extract the mod and move the asset folder from the mod folder to the same place and it'll overwrite the original files.

 

Edit: trying to install the mod itself, the textures seem to be broken? Not sure what I would be doing wrong frankly.

You're so fast, my friend!😄

 

I just found out that the game will be released next month，you have made all the necessary preparations.

 

I tried making an Estelle nude mod, and the tool worked fine.
