Using UE4 to create a base for 2D artwork

Hello, I am a bit confused about this because I am not able to find a specific answer anywhere. I am a 2D visual artist, I want to try and use unreal engine to create the main ‘base snapshots’ for some scenes that I will be painting for a music album.

So my question is, is it legal to do this, to create the base layer for the artworks that will be used as music album covers / booklets (which might be sold by the band later on)?. Am I restricted to certain assets on marketplace? or is there a specific license for this?

Yes! You won’t owe any royalties for using UE4 to render 2d images. Epic doesn’t restrict the types of assets you can use. All this is free under the UE EULA. EULA - Unreal Engine
