InTerra ~ Shaders for Terrain & its Objects

Object into Terrain Integration shader:

• Easily adjustable Object-Terrain intersection for textures and mesh normals.

• Object-Terrain textures transition based on heightmaps.

• Options for steep slopes texturing - Secondary intersection that allows you to set the intersection for steep slopes separately, you can also apply the Triplanar Mapping to it or the Distortion as an alternative for triplanar with basically zero performance impact.

Note that the steep slopes texturing depend on correctly calculated Object mesh normals !

• Parallax occlusion mapping

• Triplanar mapping Object texturing

• Detail Maps

• Emission

• Tessellation for HDRP & URP (In URP Object integration shader is supported only from 6000.0 Unity version)

• Multiple Terrains possibility - One Object Material can receive data only from one Terrain which is determined by the average position of all Objects using the Material and for multiple Terrains you will need a copy of Material for each Terrain, there is a tool for creating and managing these copies, but currently just as Beta.

Terrain & Mesh Terrain shader (Basically just like Unity Terrain shaders but with additional features):

• Distance Blending - Covering the texture in distance by its scaled up version and/or stochastic texturing

• Triplanar mapping for steep slopes texturing (for the first four layers in Built-in or eight in HDRP) with possibility for only first Layer to be triplanar to improve performance and there is also possibility to apply that one Layer to all steep slopes automatically (and possibility to move any Layer to first position)

• Parallax occlusion mapping

• Tessellation (HDRP & URP Only)

• Tracks that allow the objects with InTerra Tracks script to create the tracks on terrain.

• Heightmap Blending (for the first four Layers in Built-in and URP or eight in HDRP)

• Global wetness, puddles with raindrops and Snow.

• Color tint for Terrain Layers

• Color tint Terrain Texture

• Additional Normal Terrain Texture

The Asset also includes Mask map creator for Terrain Layers

Limitations:

• Non-Uniform scaling of Objects is not supported (some seams might appear when use)

• Seams for integrated Objects might appear just because of the way the shadows are calculated in Unity, in which case an increase of shadow bias might help. Baked/mixed lighting can make seams visible too, but I'm trying to find some workaround. The seams can also appear because of Ambient Occlusion, for example the default setting of URP SSAO highlights the intersection a little.

• Triplanar features will be applied on Terrain Base map only if you do not have more than one pass (four Layer in Built-in and URP, eight in HDRP) and you are using "First Layer Only" - otherwise the calculation would be too heavy and the Base map would become pointless.
