hi!
this is ps4 files.(Fatal Frame: Maiden of Black Water)
unpack/repack gmpk no problem
but repack g1t >gmpk then into game will freeze at loading character

Thanks for the report, but I'm going to need a little more details.

So what you are saying is that if you unpack the .gmpk and then repack it without modifying any files, everything works as expected.

What I am unclear is whether you are altering the .g1t contained in the .gmpk before repacking for the step that you say that fail.

So, is your issue that, when you unpack the .gmpk, then unpack a .g1t from the newly extracted files, then repack the same .g1t without having modified the textures, and then reimport it into the .gmpk, the game freezes?
Or are you altering the textures before repacking the .g1t.

If it's the former, then I will need to know precisely which .g1t you extracted and then repacked.
If it's the latter, then I'm afraid it's not a gust_tools issue because if you alter the textures improperly, then the game will reject them, and there are just too many ways you can alter a texture to make them incompatible with a game (and it's not gust_tools' purpose to "fix" textures that have been modified incorrectly).

So I really need to have more data about what .g1t you are modifying and how. Without this information, there's just nothing I can do about this issue.

thank you reply.
before edit texture then repack to .g1t >repack to gmpk with .g1m still got freeze at loading character screen ,so try to repack g1t no edit any texture test then repack to .g1t >repack to gmpk with .g1m also got freeze at loading character screen(only know happen on ps4)

Ah, I see that the file only contains one .g1t and one .g1m.

What you need to be aware is that right now, texture types 0x60 and 0x62 are NOT fully supported by gust_g1t, and your file uses those types.

If you extract H_YRI_H.g1t you will actually see a lot of warnings like:

This means that repacking is unlikely to work. As a matter of fact, if you look at the 2nd mipmap for 002.dds you will find that it is not extracted correctly:

This also means that repacking will not work, and that you won't be able to edit the file.

I'm afraid that I am concentrating my efforts mostly on PC games, and trying to support other platform, such as PS4, takes a lot of time that I don't actually have. So some texture formats, like 0x60 and 0x62 are only partially supported, and will remain that way until I find some time to look into it (which may never happen at all), or until somebody else sends a patch.

Therefore I will close this issue as this is not something I am planning to fix in the short term. Sorry.
