sorry for the late reply. I used vscode with an extension called “gltf tools”, and it was inside here that i was able to preview my gltf models with animations and bones. In this preview my gltf looked completely fine, but when exporting to ue5 then i only got a single frame of animation for each animation. I found that the export tool i was using were exporting the gltfs with 2 nodes per bone, and i rewrote the code of the tool to instead create the gltf with 1 node per bone instead. As seen in the image i only have 1 node per bone, which fixed the issue in my case. You could try using the gltf tools in vscode and see if your gltf also uses 2 nodes on each bone
