Hello, I would like to create a big 3D terrain which is built out of 10 collada files. These collada files represent the terrain scenes. My problem is that I do not know how to load only the terrains the player is moving on. Does somebody have an idea?

    You would need to learn about loading the terrain in chunks and create something similar to world partitioning in Unreal which will take a lot of studying and I don't know how to do that 100% yet. The principle seems to revolve around having lots of stuff happen based on the player position within the game world so you're not loading everything in at once and breaking your project or making it impossible for average PCs to run things.

    Going by these videos, it looks like for some kind of large scale game, you would need to put your terrain in bit by bit and then use the LOD settings to take care of optimisation. Might be worth trying it because I've created a fairly large island in my game and I've been floored at Godot 4's performance dealing with multiple navmesh agents.

    Game12 My problem is that I do not know how to load only the terrains the player is moving on.

    Perhaps this will help or inspire:
