Dragon Quest Builders 2 Modding: Reinject texture files from Model files

[Sapphire645]

I want to document this somewhere, but I don't really know where.

DQB2's files relating to models have a bunch of g1m and g1t all mashed together. The header first has the number of files [0,3] , then the pointers to the beggining of each file, then a bunch of data I haven't deciphered yet.

I made 2 very shoddy python files that can reinject texture files into the .unpack to reimport to the linkdata. It only works for files that have only 2, like character or weapons.

How to use:
-Have the scripts on the same directory as the unpack
-Run ModelUnpackExtractor, and write the name (including the extension) on the terminal
-It will generate a g1m and g1t file. Edit the g1t file as you would a normal g1t file.
-Run UnpackG1tReinjector, and write the name (including the extension) of the .unpack file. It will reinject the .unpack.g1t into the .unpack file.
-Reimport as normal

Example:

Has no one documented this before? Compared to everything else I find it sad that as a community we got past injecting normal textures but couldn't figure this one out.

DQB2ModelUnpacker Here are the tools to edit the models... Can't erase the thread so I guess I'll leave this here for anyone that might stumble upon it someday...

Nice work, Sapphire645! I was wondering if there's a way to handle UI textures for fan translation of the game. Both for the original DQB and DQB2. Do you happen to know anything about this matter?

Its all on the UI image file, just replace the file with custom images and volia! There's also a main text file with all the written UI text.

Yeah, I already managed to translate the text. All that's left is handling the phyre wrapper for the dds textures. I can't find a way to extract and replace them with my edited ones, and then repack them back into a phyre wrapper to be used in the game. All the tools available only support the PC version of the game (well at least the ones I found).

Here's a sample of a texture of the game!

It shouldnt be too complicated. The main file of the game (DQB2) is the linkdata. This video has all the tools to replace .dds textures of the game. The only thing you'd have to do is extract the icon sheet, which is a big file containing everything, and replace everything there.

Here is an example of how the image looks like (its shrunk down and .png for visualization purposes). Each language has a different mapping, so based on the language you're basing the translation on you'd have to use a different sheet. For example, european switch version has 5 sheets for its 5 languages.

Forgot to add, all versions of the game are the same. The index number of the files will change depending on the version, platform, region, etc... so I can't give you a number, but the sheet is after the "tips and tricks" images, which take a whole lot of space so it's easy to land on, and before the text files. Its also before the island name files and the boss monster name files.

It's also the first file after a bunch of empty index files if I'm remembering correctly.

If you have the whole game extracted then it'll be easier to pinpoint the file.

(Edit, on the European version I use it's index 600)

Ok, it seems to be pretty straight-forward indeed! However, this is for DQB2, right? Could you please try and convert the sample phyre file I sent you before? It is from DQB1, so now I'm curious if the original game is harder to work with than the sequel

I think I have my answer: DQB1 uses a different structure for encapsulating assets (nxarc). I didn't know that because actually a friend of mine is translating the game and it seems he already managed to extract the textures (in phyre format) but doesn't know how to proceed any further than that. And that's where we are now.

I... unfortunately have no idea about DQB1, sorry. There are tools online that convert Phyre into normal dds and back, although I can't tell you which one would work as I have no experience with it.

DQB1 and DQB2 were "developed by different companies", as in, DQB2 uses Koei Tecmo's own encryption format, while DQB1 uses something else. So they are fundamentaly different in that aspect. Tools that work for one game will not really work for the other.

Yeah, that's exactly the case here. DQB1 uses Phyre Engine, an obscure engine from Sony and every tool I found online that converts phyre texture to dds, only work with the PC version of the files. It's always like this lol

Anyway, thanks for taking your time to try and help me! I appreciate it!

You can try to compare the PC version of the same file to the console version with HxD, the differences might be small enough that you can convert the files to something the tool can read manually. Might be worth a shot?

Yeah, I didn't come to that. I forgot that completely, lol
But in fact, as I said before, I'm not the one actively translating the game. But I'll give it a shot! I'm just not good at all at HxD but I know how to at leat make something out of the magic and the headers a little

Welp, no deal! On PC the game was developed with Unity, and on Switch, it was with PhyreEngine. Guess I'll have to keep looking
