I’m trying to create a map for some characters to travel; to do so, I have navigation mesh creation in mind.
The problem is more of an aesthetics issue: the map is made from a height map, which means the mesh stops “brutally”. The camera can only move into the map area, and going to its edges, can see the gap around it.
I thought about creating a second ground mesh from the same height map, but with a bigger width; unfortunately the “mountains distribution” over it is not the same as the map mesh, due to the extended width.
I didn’t know about alpha map !
I like the effect it gives on borders, but unfortunately my ground is big, so I need to repeat the texture (uScale > 1), meaning I can’t use alpha on it.
Moreover, the alpha graduation would not apply to meshes being around the edges of the groud.
