Auto generate UV lightmap (second channel)

I’m new in Unreal Engine and I’m previously created game in Unity.
I have many assets from my Unity projects and I would like to transfer its to Unreal Engine. All went good except one thing: UV second channel. In Unity it generates automatically and also works fine. How can I do that in Unreal? Is possible any better way to do this than edit all my 2000 meshes in 3D software like Maya or 3ds Max?

Thanks for your reply.


Don’t use the generate new uv’s, it’s a bodge job way of creating a second uv channel.
Create the second uv channel, (light map uv) in your modelling program. There’s a tutorial on light mapping here,*** TraptCG***]( :cool:
