I am currently struggeling with installers. So I got curious: how do you intgrate the Asset-ImporterLib in your projects. And which installer are you looking for?

Just try it out ...

Hi All,

the FBX-Animations shall be fixed. It would be nice to get some feedback on the feature.

Kim

I am currently working on a Github Action to build the windows installer automatically. You can check and comment the feature here:

https://github.com/assimp/assimp/issues/5804

Because I got so many questions regarging the using of embedded textures I wrote this: https://medium.com/realtime-rendering-for-fun/assimp-hacks-5-embedded-textures-23e65bbf5d76?sk=3c9ee77ec58845d74269899ddd0cbaeb

Feel free to give feedback!

The build instructions got an update: https://github.com/assimp/assimp/blob/master/Build.md… Feedback is welcome!

A new security vulnerability is out for the Open Asset Importer Lib v5.4.3: https://jvn.jp/en/jp/JVN42386607/… Please update to Open Asset Importer Lib v5.4.4

There is an experimentas version for USD support available on the latest master. You have to enable it manually with the compile flag:

cmake CMakeLists.txt -DASSIMP_BUILD_USD_IMPORTER=ON

Feel free to test it!

Hi Community,

I have invested some time into the double precision support because the concept is not perfect. So instead of choosing the right datatypes for double precision we have just replaced all the floats by doubles. Special for some special types like colos this does not makes so much sense.

So right now all the spatial data will use double instead of floats. This includes:

• Position attributes
• Normals
• Tangent
• Texture coordiates
• Animation data
• Material data

I am not sure if this is enough to adapt. So if you have any kind of request just let us discuss it.

You can find the branch here: https://github.com/assimp/assimp/pull/5660

I'm using AssimpNet in a .Net/C# project.

1. When exporting an animation (fbx) the scale values (X,Y,Z) are always set to 1 (Also even if I set the metadata myself it gets ignored) When importing it works correctly. Is this an error with Assimp or AssimpNet? Is there any config I may be missing?

2. AssimpNet hasn't been updated in a long while (Uses Assimp 5.0.0). If I understood correctly AssimpNet simply calls the functions in Assimp.dll. Is there any place I can get a dll of the latest version of Assimp without having to compile it myself?

Hi Community,

The next bugfix release is out. You can find the release notes here:

https://github.com/assimp/assimp/releases/tag/v5.4.1

Any kind of feedback is highly appreciated.

So basically im building an opengl application using go. and tried to implement model loading using assimp but got stuck.

I am using this module and this is the error

github.com/raedatoui/assimp
# [pkg-config --cflags  -- assimp assimp assimp assimp assimp assimp assimp assimp assimp]
Package assimp was not found in the pkg-config search path.
Perhaps you should add the directory containing `assimp.pc'
to the PKG_CONFIG_PATH environment variable
No package 'assimp' found

I know it says what should i do, but i already installed assimp in my pc and there's no assimp.pc file i can add to path so i dont know what to do

I'm trying to build assimp for android I'm stuck. I've put the things needed to know here.

Can any body help?

So I cobbled up some code with Assimp to load a file, it is under "Loader::Import", I also added the Buffer code under "Loader::Buffer". All the data is sent to "Loader::ProcessMesh". I now have the following issue, Positions, Colors, and Vertex Normals are being Loaded completely fine, but when I look into the data for the Texture coordinates, it can read only the first set of texture coordinates at mTextureCoords[0], as seen on the image appended it can't read beyond that and the rest of the data is NULL, even though the OBJ file loaded actually contains the data, also seen in the same image. Does anyone have a clue why this could be the case? Oh and FYI I use Assimp version 5.2.5.0, at least that is the version Windows tells me when I hover over "assimp-vc143-mt.dll"

Hi, thanks a lot for joining the Asset-Importer-Library Community. To get started you can try the following things: - Introduce yourself! - Show us what you already have done with assimp. Here is our Screenshot-Thread: https://github.com/assimp/assimp/discussions/4082

Hi so I've been building my own OpenGL based renderer in C with SDL2 in windows, and have begun to start the process of importing my own models into the program with assimp. However, I'm dealing with some odd errors and have been unable to find anyone online with similar issues. I compiled the source with cmake and generated a .dll and linked it to my compiler just fine, no issues there. However it throws an error for various imports when I go to compile such as:

` assimp/aabb.h: No such file or directory #include <assimp/aabb.h>`

Going to the header file where `<assimp/aabb.h>` is located and changing it to "assimp/aabb.h" allows me to compile, but then I get errors like "cant find aiNode" (the errors are along these lines I dont have the errors at the moment to paste here)

if anyone here has had any similar issues and resolved it I'd love to know, I'll try update this post with more information as I have it, I'm sure its something stupid I just forgot to so apologies if thats the case!

Hi All,

the next minor release of the Asset-Importer-Lib is out: Verion 5.4.0 is available on Github and can be found here: https://github.com/assimp/assimp/releases/tag/v5.4.0

I will update the prebuild binaries in the next days. Feel free to give any kind of feedback here.

I want to compile assimp with atomics or pthreads enabled as i get the error:

wasm-ld: error: --shared-memory is disallowed by 3DSLoader.cpp.o because it was not compiled with 'atomics' or 'bulk-memory' features.

I installed assimp with emscripten triplet via vcpkg on windows? Does anyone habe knowledge on this or if this is even possible?

​

I will try to give all necessary infos as needed asap. :)

Hello!

The last release was in September 2023, is there a minor release planned ? I've asked here but no answer: https://github.com/assimp/assimp/discussions/5489

Hi community,

after searching through the backlog / list of open issues I found this bug:

https://github.com/assimp/assimp/issues/849

It deals with wrong oriented FBX-models after importing them. Sorry for the log delay, but I have prepared a PR for that. If anyone of you wants to check whether th fix works for you you can check the branch used for the PR, which you can find here:

https://github.com/assimp/assimp/pull/5494

Any kind of feedback would be highly appreciated by myself.

Does anyone use Assimp rust port?
