Support landscape material.
If you want to use snow trails on your landscape you can use a SnowActor_Land who will follow player's camera and only draw limited area around player's pawn.
You can also create a SnowActor who will draw proven area with own render target,it's useful for trails you don't want fade by distance.It can use with Niagara.
Tow draw ways are supported:
Use a texture to draw trails which is useful for simple shapes such as sphere,box,or car.
Use a scene capture 2D which follows your actor to draw accurate trail with depth.Character's footsteps and complex skeleton mesh with animation could draw their trails accurately by this way.
To save computing time
Drawers won't draw until it's moving
SnowActors will update only when draw information updated
Tessellation depend on distance.
A debug board Actor is equipped to show how height map are drawn.
You can modify banked shape and blur quality by material used to draw render target.
Snow quality is controllable,you can change render target size and capture orthogonal width,capture render target size.
The trail is drawn on the render target
