Please watch this video as it does a much better job showcasing the error than what could be described by text:
This error is specifically referring only to the animation of the morph targets. The morph targets of the model have no difficulty getting imported into UE4, and the animation morph target data goes through just fine.
What is frustrating is that when I select an animation, it will only animate the very first frame of the morph target, and the morph target refuses to animate the remaining keyframes. In the video, you can see that the keyframes are there, UE4 is just not animating.
What I noticed after playing around with it is that the moment I edit a single keyframe ever so slightly, then suddenly the morph targets start animating. However, the moment I select ‘apply’ and/or ‘save’ then the bug occurs again. I have no idea why this is happening, or what I could possibly do to fix it. Help would be very much appreciated!
