I'm a beginner with QGIS and Unreal Engine.

I have three shapefiles in QGIS:

1. Lakes
2. Rivers
3. Biomes

I'm trying to figure out how to process or export these shapefiles in a way that makes them usable in Unreal Engine for a project I'm working on. It would be great not to use any plugins if possible, and stick to the standard tools available in QGIS and Unreal Engine.

Specifically, can you provide guidance on:

• Any preprocessing steps needed in QGIS to prepare the data?
• The best export format for Unreal Engine Compatibility?
• How to handle the three different types of data (lakes, rivers, biomes) effectively?
