Godot/live2d crash when loading models other than samples.. #75

Closed pillowtrucker closed 2 months ago

pillowtrucker commented 3 months ago

Hi! I've been trying to load https://github.com/n0099/TouhouCannonBall-Live2d-Models/tree/main/Rinnosuke and/or https://github.com/andatoshiki/toshiki-live2d/tree/master/%E4%B8%BA%E7%BE%8E%E5%A5%BD%E7%9A%84%E4%B8%96%E7%95%8C%E7%8C%AE%E4%B8%8A%E7%A5%9D%E7%A6%8F%EF%BC%81Fantastic%20Days/1399100 on linux. When I load the asset to attach it to the Model node, godot crashes with free(): corrupted unsorted chunks or

Fatal glibc error: malloc.c:2594 (sysmalloc): assertion failed: (old_top == initial_top (av) && old_size == 0) || ((unsigned long) (old_size) >= MINSIZE && prev_inuse (old_top) && ((unsigned long) old_end & (pagesize - 1)) == 0)

I'm not able to get any more information from gdb because godot exits instead of propagating the error...

When I try the same thing with the Niziiro Mao model, everything works fine... I'm running godot 4.2.1-stable. I've tried building with llvm and with gcc, but there was no difference. Any idea what I'm doing wrong ?

I figured out how to get more useful debug info:

it seems that it's failing to parse the motions and/or trying to free some memory that it didn't actually allocate

pillowtrucker commented 3 months ago

The crash happens immediately upon trying to parse the first motion - if I try to step beyond that I immediately get the crash. I don't know if even the path to the motion is correct, but I'm assuming it's not simply that.

There are some difference in the json schema of the motions from the working model and the ones that crash, for example the "UserData": [] array is present in the crashing models, not in the working sample. There are also some differences in the headers: broken:

working:

I don't know if this is relevant or important.

According to the information you provided, you are able to load the sample data (map_pro) provided by Live2D Inc., but the application crashes when you try to load a specific model. This is also apparent from the error logs.

In such cases, it is recommended to investigate using the loading options in GDCubism.

fig1

This feature has been implemented since version 0.4 and can be specified with the following options under Assets:

Firstly, before loading the Live2D model into Assets, try unchecking these options to see if it can be loaded.

Each of these options allows you to exclude the loading of Expressions and Motions when loading the Live2D model.

If you can load the model with these options unchecked, it is highly likely that the Live2D model you are trying to load does not have the correct structure.

pillowtrucker commented 3 months ago

Disabling motions in Godot stops the crash, but the display is just some background color. I'm not convinced the model is the problem though, as it works with every other viewer, including the official one from Cubism.. Here is my godot: Screenshot_20240406_104154 Here is Live2d official viewer: Screenshot_20240406_104309 Here is the web viewer https://guansss.github.io/live2d-viewer-web/ : Screenshot_20240406_104425 The model I'm trying to use is https://github.com/Eikanya/Live2d-model/tree/master/为美好的世界献上祝福！Fantastic Days/1399100

Regarding the Load Failure

Thank you for verifying with the Load Motions checkbox unchecked. If the checkbox is unchecked, it seems that it does not crash, which suggests that the *.motion3.json used in the target Live2D model has an unexpected data structure.

GDCubism is responsible only for rendering in GodotEngine, and the data itself is directly using the CubismNativeFramework provided by Live2D Inc.

While it would be better not to crash even with an incorrect structure, any bugs occurring in CubismNativeFramework are outside of GDCubism.

There's no choice but to handle data-side issues individually, but a similar situation has been discussed in a previous Issue, which might serve as a reference. https://github.com/MizunagiKB/gd_cubism/issues/52

Regarding the Issue of Live2D Model Not Displaying Correctly

This issue was due to the ppunit value specified in the Cubism Editor not being handled appropriately. I have made a correction for this bug. https://github.com/MizunagiKB/gd_cubism/commit/a1868c830f31755eab388e6494b639b0ae41da78

https://github.com/MizunagiKB/gd_cubism/tree/bugfix_calc_ppunit

With this change, if you build with the 0.6 branch, it should display correctly.

Thank you. I'm still trying to debug the motion issue. I think the problem is that the .moc3 files are for version 3.3 of Live2D SDK, and this is version 5. I can replicate the crash with the native samples https://github.com/Live2D/CubismNativeSamples and it gives slightly better debugging information:

It still gives the confusing errors about memory corruption during JSON parsing and it doesn't really hint at the fact that it's actually the moc3 files that are incompatible, but I've tested different configurations of working and broken JSON and png files. The crash is in different places then, but it always happens when it's trying to refer to the moc3, even if I make the JSON and png files identical to a working model.

It's disappointing that the way Cubism chose to handle this is with a weird crash, especially since their official viewer opens them correctly, but it's not your fault :+1:
Their viewer is also in java, so maybe they use some other library and give the users a different one.. Or maybe they have several different versions active to handle the incompatibilities..

pillowtrucker commented 2 months ago

I'm a dunce. I spent hours looking for something in the framework code to figure out if the moc3 version is used anywhere. I finally just tried your script from https://github.com/MizunagiKB/gd_cubism/issues/52 and that fixes the motion files and loads the model. But I still don't know what they've done in CubismViewer that this is not necessary there.

pillowtrucker commented 2 months ago

I'm reopening this as there are several options for backwards compatibility that I think might be worth trying. https://docs.live2d.com/en/cubism-sdk-manual/compatibility-with-cubism-5/#facemotion-fix I will try this first

MizunagiKB commented 2 months ago

The content of the transition destination describes the method to support compatibility with Expression behavior.

The content describes the operation of Expression, and the method is to replace the Expression processing, which is currently performed by a dedicated class, with the Motion class implemented in the past SDK.

As for the method of support, it is not an adjustment with arguments or properties, but a method of rewriting the code that each person has downloaded. Therefore, it cannot be supported on the GDCubism side.

On the other hand, if we try to incorporate the CubismNativeFramework itself to support it, different license conditions will mix, so we are not considering incorporating the code on the Live2D side.

Even if there is no problem with the license, it is not good to incorporate it from the point of maintenance.

However, I think there are people who need such changes and differences in operation. People who use GDCubism will probably work while reading BUILD.en.adoc, so if you add it as additional information in the document, the opportunity for people who need it to notice may increase.

I will add it as additional information in the document.

pillowtrucker commented 2 months ago

I've ported your python script to the framework now and opened a PR with Cubism. The expression logic is a different issue, I think. It's kind of weird how they've done it and not very convenient, but it doesn't seem to be related to the crashes. Thank you for your time and work on this!
