I “solved” the problem: No matter what i did, i could not get that specific animation working in any context. What did work was exporting it to an .FBX with preview mesh, importing that into 3DSMax, then exporting it from there and importing it into UE4 again, without making any changes.
I’ve created a custom dodge roll animation using additive layer tracks to modify the default third person idle animation. The animation shows up fine in the preview in Persona:
The thumbnail in the content browser is affected as well:
However it does not work when using it in montages, or playing it directly via the Character blueprint with a custom event, or via a state machine in the Anim Graph:
The animation is simply stuck at the first frame and doesn’t move one bit. The roll involves root motion, and if i disable root motion in the animation, the root itself moves, but everything else stays locked. I also tried exporting the animation to an .FBX file and reimporting it. In that case, the newly imported animation does not even work in the Persona preview or thumbnail. Thank you in advance.
What i meant is, the animation does not even show up in the Preview of the Montage. Unlike other, premade animations for example. If i drag the standard jump animation into the montage, it plays just fine, but mine doesn’t work.
