Animation and UVs to work in UE

Hi all. I am entering the Snow Challenge and plan to make a snow tornado. I made a keyframe anim in Blender but forgot to unwrap uvs for the mesh. My texture scale looks off, and I tried applying scale. I must be missing something. I was transforming in Object mode and also using Proportional edit in Edit mode. I have a video of the animation here.

I have a video but I cant send it on here it says. When I apply all it messes up the animation position and such. Does anyone know how I can get this to work?
PS: I’ve never exported a full animation from Blender to Unreal.

Thank you for any help.

you should be able to upload the video to youtube and post it here.
I cant help you on the blender-part, as I have zero experience with it.

ok. I can upload a video of the animation and then show the UVs.

Here is the video link. I apologize if my family is talking in the background.
