Just had a few questions for people who have worked on large open world terrains before.
Do you create one large terrain or a bunch of different chunks of terrains?
If divided into different chunks how do you manage to line up and render each of the terrains including all the objects on each terrain?
What comes to mind are games such as mmorpgs, fallout, ect. Anything with massive terrains which have different areas to explore.
I used a bunch of terrain chunks with one chunk per scene. Beforehand i stiched them at the borders.
Then when one gets close to the border, i load the corresponding scene additivly, then set the neighbours.
If one gets to far away from a terrainchunk it is destroyed.
Also make sure that you move the world back to the origin so you could basically run forever without experiencing imprecision.
However, one has to admit that this approach would only be suitable if you have pro, otherwise serious hickups would occur when loading a new scene if its filled with objects additionally to the terrain.
