I am creating a extreme large map(most likely more than 200km) using landscape in UE4.
It is foreseeing that level steaming will be used. However, when I try to create more than one landscape and place next to each other, there is space shown as below:
Here is the heightmap file used:
Landscape 1
Landscape 2
For my whole landscape, the highest point will get over 5km.
Both heightmap is generate from other software, and that software can only export 8-bits png image, I properly will convert the heightmap to 16-bits grayscale and blur the whole image to smooth the edge.
Before I go on to convert the heightmap to 16-bits grayscale, I think I should solve the connecting problem of two landscape before I go on.
