Could you share a quick video with how it looks now? You said changing the initial state didn’t work, but did it look right before interacting with it?
I think you could also try reimporting the mesh with the Use T0 as Ref Pose set to True. What it does is basically it updates the skeletal mesh pose based on the first keyframe you had exported. So make sure that when exporting the mesh, you have the drawer in the closed position.
Another solution for what you want to achieve would be to use a Static Mesh for the drawer instead and use a Timeline to animate it opening and closing. You can connect the flip flop to Play/Reverse to if you interact with it quickly, it’ll just go back from the current position without jumping the animation. It limits a little bit what you can do, but if you just need a linear animation, it should work pretty well.
If you’re not familiar with Timelines, you can check some documentation here: Creating Timelines in Unreal Engine | Unreal Engine 5.5 Documentation | Epic Developer Community
Please let me know how it goes, I hope it helps this time!
