Better blend with RVTs?

[motorsep]

I finally got simple RVT blend between static mesh boulder and static mesh terrain working:

Still, you can see intersection line between the two (although it looks better than without RVT blending, it’s still not what I am after).

How can I adjust mesh normals on the boulder so that geometrical transition is smoother, eliminating intersection line entirely or really minimizing it ?

Thanks

P.S. I can’t use DFs nor pixel depth offset.

try this: Ue4 - Terrain Mesh Normal Blending with Virtual Textures Guide! — polycount

helps if your landscape normals are in world-space since the other mesh(es) cannot always know tanget-specific stuff about the landscape.

technique works great for me: Finally getting the hang of the newer heightmesh in UE426! - Album on Imgur
