So i wanted to have a go at using a PBR rendering software to see how the normal maps would look in real time. I also found that marmoset has a plugin that unreal engine and has the ability to export it as a unity package which is perfect for me since i want to turn this into a game environment. I used a free trial of marmoset but ended up buying it because it was so fun to use, the shaders and lighting provided with the software is fantastic and easy to use. The viewport as well is easily manipulated and has excellent quality. Altogether it is an excellent software and very fun to use.
Below are some renders to show how the normals look on the models.
