So essentially I made an animation of a rectangle moving up and down to use as a door the player would have to get through. And I’m really new to unreal so maybe I’m just being stupid, but when I imported the animation from blender, the animation would play but the collisions were weird. When the player ran into the rectangle at certain times collisions would work but other than that collisions didn’t work. I tried adding collision boxes to the mesh the animation was applied to, and I tried playing around with the collisions of the mesh and animation, but I cannot get it to work. I was wondering if anyone could help, sorry if this is a stupid newbie question. Thanks for the help.
So, in UE4 animation works only with Skeletal Mesh. When you importing your file, Unreal creates some assets together with mesh. One is skeleton(if you don’t create it in Blender), and other is PhysicsAsset. Last is - “collision” for skeletal meshes.
In your case, if box moving up and down only, i recommend use blueprint instead of animation.
Check the documentation, its contains lot of information:
