Product Version94.1.1+git 
Target Version95.0Fixed in Version 
Summary0003972: Assimp .3ds support broken in 94 and 94.1.1+git
DescriptionThe latest Zero-k test version uses .3ds for numerous wrecks, these work fine in 91 engine version... but produce this or a similar error on 94.1.1+git engine version.

[f=0000678] Warning: could not load model "leveler_d.3ds" (reason: [AssimpParser] Model Import: Chunk is too large)

Again, all .3ds models work _perfectly_ fine on engine 91. (I even played a 5v5 on ZK test with engine 91 earlier today)

I tested both mentioned engines...
All .3ds models fail to load, low poly / high poly / with and without smoothing / ETC
Steps To Reproduce1. get latest zk:test version (currently r11266)
2. Build/spawn any unit with a .3ds wreck
(Here are the unit names of a few, for convenience:
corlevlr
armrock
blackdawn
corvalk)
3. Kill it in a manner that produces a wreck
4. Wreck will not load, an error similar to above will appear.
Additional InformationPweese Fix.

 It works for me with zk-r11267 and spring-gb7c15b9.

Maybe the file(s) you have are locally corrupt?

 Rafal First alerted this to me and said on public online zk:test + latest engine server the problem occured, my local testing confirmed so I posted here.

Testing again this morning:
I've redownloaded my engine (spring_{develop}94.1.1-1027-gb7c15b9_minimal-portable.7z)

and redownloaded zk:test using prdownloader.

Still occurs exactly as described.

 Same issue on 94.1.1-1027-gb7c15b9 and Zero-K r11275.

Without knowing anything else about it: May be OS specific or graphics issue?
I'm on Microsoft Windows 7 Home Premium Edition, 32-bit Service Pack 1 (build 7601) and ATI Radeon HD 5700 Series

EDIT: Running the "worksforme" replay also gives the issue.

 Windows XP Pro SP3 elite hacked version...
ATI Radeon HD 4650
AMD Phenom II 965 X4 Black
4 GB ddr3 1337 ram

Again, all works on engine 91.

 I *assume* it is a platform issue because while libassimp was updated a few times between 91 and 94, there were *no* changes to the 3DS loading code.

In particular this looks susceptible (comments mine) to generating the "Chunk is too large" error:

class Discreet3DS {
    ...
    struct Chunk {
        uint16_t Flag; // UNSIGNED
        uint32_t Size; // UNSIGNED
    } PACK_STRUCT;
}

void Discreet3DSImporter::ReadChunk(Discreet3DS::Chunk* pcOut)
{
    ai_assert(pcOut != NULL);

    pcOut->Flag = stream->GetI2(); // SIGNED (StreamReader.h --> int16_t)
    pcOut->Size = stream->GetI4(); // SIGNED (StreamReader.h --> int32_t)
    ...
}

 Please test {develop}94.1.1-1031-g274e6f1 when it becomes available.

 Error still occurs on 94.1.1-1031-g274e6f1 in the exact same manner

-unrelated below-
Also, I get IMMENSE lag on that engine version, ZK runs at ~ 5 FPS on startup, in comparison to usually running over 100 most of the game.

 i think i got it:

sizeof(Chunk) is 6 on linux
sizeof(Chunk) is 8 on windows

-> __attribute__((packed)) is ignored ?!
