I took a look at the channel various types of music many beautiful pieces
But to monetize the music in UN5 you need have the rights of the music if I have not misread the conditions of use of Epik unreal engine if that’s not a problem The sky as the limit
In my opinion for the kind of music of the channel you need fractals tipe stuff from the 90s if the thing is 2D or can you make it look 3D with 2D illusions it can work a fake 3D
3D fractals in real time 4k is science fiction 100%
