animation flip during 1 frame ?

Hey !

i m working on roller shutter animation. I did a simple animation on 3DSmax, and exported it on FBX ( with baked animation option )

but like you can watch here : - YouTube

I ve an issue : during animation, the shutter flip on X axe, during 1 frame !?

Do you know why ?

Thanks,

please ? :confused:

well that is certainly strange … don’t know what might cause this but have your tried turning off collisions and physics for the mesh in ue4?

Did you try to check the “Preserve Local Transform” box when importing your FBX ?
