Cant play fbx animation correctly

Open GitCodeBoy opened this issue 2 years ago • 9 comments

I loaded a fbx file and the f3d window can show the model, but when I press the space key to play animation,f3d cant play animation correctly like other software like motionbuilder or maya.

Here is the test fbx i use :https://github.com/GitCodeBoy/test-fbx , when I open it on motionbuilder or 3D Viewer window 10 ,i can see a catwomen walk around.

To Reproduce Steps to reproduce the behavior: 1.open the f3d.exe 2.drag the test file into the application window 3. press 'space' 4. find the model get strange 5. image

Expected behavior play animation correctly

It's an issue in Assimp, it has been reported many times, for example here: https://github.com/assimp/assimp/issues/4620 https://github.com/assimp/assimp/issues/4487 https://github.com/assimp/assimp/issues/3390
Animations were working well in Assimp 5.0
Let's keep this issue open until it's fixed in Assimp.

这是 Assimp 中的一个问题，已多次报告，例如这里：assimp/assimp#4620 assimp/assimp#4487 assimp/assimp#3390 动画在 Assimp 5.0 中运行良好 让我们保持这个问题开放，直到它在 Assimp 中得到修复。

Are there any temporary solutions?

You can try to build f3d yourself with a downgraded Assimp version 5.0

Please note there is some texture issues with assimp 5.0

Another workaround would be to convert your fbx to gltf/glb.

f3d does not show anything after i convert my test file to glb by Windows 3D Viewer 'Save as',the glb file can be opened by Windows 3D Viewer corretly image

Could you share the .glb file ?

Could you share the .glb file ?

I uploaded it on my test repo :repo

Could you share the .glb file ?

If I need to do anything else when converting FBX files？

Looks like we forgot to check this one @Meakk

I think that's because the model is very large and the frustum culling isn't working when there is an animation (it is based on the T-pose bounding box).
It's a duplicate of https://github.com/f3d-app/f3d/issues/57

Closing as duplicate then. @GitCodeBoy you can work around it by positioning the camera in the right location.

mwestphal avatar Feb 02 '23 17:02 mwestphal

Keeping it open for the Assimp bug though.
