Terrain texturing in unity is really poor, it only allows a diffuse and normal map. Is there a way for terrain to use the “standard shader” from unity5 ? So it works exactly like on materials beside terrain. It’s called PBR, right ?
I really need higher quality textures on my terrain(s).
That’s easy. Just use “Built In Standard” material in Terrain Settings. You can use texture maps for albedo, normal and smoothness, and a float to control metallic value.
What do you mean Normal and Smoothness? did you mean The Smoothness value are taken from normal alpha?

This is what the Add Texture dialog looks like when you use built-in standard material.
The RGB channel of the first texture is the albedo color, while the alpha channel controls the smoothness value. The second texture is used as the normal map.
Ah i see, btw sorry if this off topic but is there a plan to implement height based texture blending for terrain splating? since we get limited texture slot for terrain atm.
