My naming is horrible so I am not sure if the title of the post properly conveyed what I am trying to do. In any case, here goes:
My landscape is made in World Machine. I export 6 different weight maps for 6 different landscape layers, import it all into UE4 and it works like a charm. The problem is, my final landscape will be HUGE and have different biomes. So at point A the 6 layers might be describing a jungle environment but at point B it might be a snow region.
Bottom line is in the snow region I need an entirely different texture set than what I got in the jungle region + a smooth transition between the two.
My ideas so far consist of material blending and vertex color. Anyone done something similar in the past and / or has a few pointers?
