In Unreal Engine 4, beginners mostly suffer because they can’t make a scene. But, %66 percent of people get across that very quickly, and almost everyone gets stuck on the issue of lighting, positioning props, etc. (Well, as far as I know). Well, I have a tactic. Which is, randomly making a scene, then getting inspiration from that scene to make the scene you desire.
Material instances are fairly simple, but they are really useful. If you use material instances, you won’t have to make ten whole materials just to have a variety of colors to choose from. They use a base material that limits how many nodes, values etc. you have by assigning parameters to the ones that are used, and keeping the other nodes and values constant in the base material, and when an instance is created only the nodes with parameters can be used.
