https://assetstore.unity.com/packages/vfx/shaders/terrain-blending-pro-187819

This freebie is a combination of a basic PBR Surface shader and a modified terrain shader to easily mask the intersection between models and terrain.

Basic features are:

 - PBR-based

 - Albedo, Normal, AO and Emission support for your assets

 - Albedo and Normal support for the blending texture

 - can easily be extended with basic shader know-how

 - parameter-based perfect tiling with the terrain base texture

 - Snow-Mode: Add some blending on top of your assets for an even more coherent environmental look

 - Inflate-Mode: Inflates your mesh in the blending area to have it blend with the ground even better

This kit also contains an example scene with textures, materials and a model to show how it works.

The shader for the meshes requires Shader Model 3.0 or higher while the modified Terrain shader requires Shader Model 3.5 or higher.
