Terrain alphamap fade
How do I disable this, without having to change the alphamap resolution: 
It is fine if it is just squared.
Doesn't appear to be an easy way of doing this.
How about putting a plane on the your terrain and setting it 0.01 above it.
Of course that's only going to work on flat terrains which may not be what you want but your image looks like a flat terrain which is why I'm putting this in answers and not comments.
EDIT:
I'm pretty sure it can't be done on the terrain. I did a bit of research before answering and found this and this
None of them come up with a better answer than placing a plane/mesh above the terrain. You could create a mesh based on a given coordinate on the terrain and build it so it shapes the same as the terrain as you've not got a flat terrain, not tried this but terrain.sampleheight would probably a way to achieve it.
The problem is that will become costly as some posts in those questions show. That said costly a few years ago may well go unnoticed now.
I actually have bumpy terrain it is just hard to see on the image above, so does anybody else have any suggestions?
