Unreal engine Motion blur

I'm having a problem with motion blur in the unreal engine. I have to unlock the display rate at runtime to have proper motion blur in the movie render queue, but if I do. The path that was imported from 3ds Max is not smoothed. Wheels will start jiggling. I tried to bake the animation and import as a fbx, and still not working. If I try to smooth the curve manually, I ll lose some details. Please help...
here is some photo of the issue

Most likely there is an interpretation between the keyframes that is the issue. So if you render a frame on the keyframe it is correct but if you render between two keyframes you have this strange issue with wobbling wheels.
The best is to make sure to animate in the same FPS as intended to be rendered out in Unreal.
So if you intend to render in 30 frames per second you need to animate in 30 frames per second.

I went back to 3ds max and double check make sure when I exported the same frame rate I use in unreal (24 fps) and the same problem still occurred…
I have no problem render with lock display rate at runtime but if I do there will be no proper motion blur

Another issue that can arise is if the transforms are non uniform. Does the export log stat issue with uniform meshes?

There is not, and I'm still having this issue, but I can fix it by changing the export frame rate in 3ds max from 24(desire frame rate) to 240, but now I'm having issues when I'm importing the data smith

What version of CDS are you using? Do you have the latest?

Did you ever fix this issue?
