How to create a seemingly endless world?

I am facing a challenge in creating expansive worlds within UE5 and would greatly appreciate some guidance and insights from experienced users. Here’s the situation: I have designed a landscape for my level, but I find it to be too small for my vision of a vast world :slightly_smiling_face:. To overcome this limitation, I decided to create a new level and maximize all landscape-related settings to achieve a larger size. However, I noticed that this approach consumes a significant amount of resources, and my RAM utilization reached 100%.
