Snow Trail

Adds a terrain where objects leave prints and trails. To affect the surface the object has to be lower than the floor.

Usage

1- Click the “Add New” button
2- Select the collection with the objects that will affect the terrain in the modifiers tab
3- Animate the objects to go lower than the floor to affect it.

Parameters

▼ TERRAIN
Size X: X axis scale
Size Y: Y axis scale
Terrain Texture Scale: The scale of the texture displacing the terrain
Terrain Texture Displacement: Displacement multiplier to make the terrain uneven
Terrain Density: How dense the terrain is when interacting with other objects (more dense results in sharper edges, less dense makes soft and curved edges)
Subdivisions After (Heavy): Adds a subdivision surface after the simulation to smooth the geometry

*Keep subdivision at 0 to generate the simulation, as it will greatly increase the simulation time, once done you can set it back to 1

Smooth: A control to smooth/relax the mesh

▼ PRINTS BORDER
Border Height: How high the border of trails will displace
Material: Replace terrain material

*If you use another material and need the UVs for the terrain, you can use the Attribute Node in shader nodes with the attribute “UVMap” like I’m using here:

Collection: Set the collection with the objects that will affect the terrain
Low Res Preview: A switch to lower the resolution to speed up previews

*To create the animation I added a second hidden plane a bit lower than the generator with collision physics and dropped the monkey heads that will hit that second plane and since they are lower than the generator they will leave a print.
