Overview
Roadscape features one main generator and a bunch of extra generators, here are their names and functions.
Main Road Generator
The Main Road Generator is the generator responsible for designing the road system and to apply terra-formation to your original terrain.
It is also the generator responsible for generating bridge and tunnel bases, as well as a subdivided path mesh which is used by extra generators.
This is the most performance heavy process.
Bridge
The Bridge Generator is the generator responsible for turning the bridge based output from the main generator into actual bridges.
3.1 LTS features a new bridge generator, in addition to the legacy one.
Roadscape is planned to have different bridge generators, reflecting different types of bridges we can find in reality.
All future bridge generators will have the same geonode system as the new one introduced in 3.1 LTS.
The legacy generator is meant to be deprecated.
Auto Markings
The Auto Markings Generator is the generator responsible for turning the subdivided path mesh output from the main generator into actual road markings.
It generates dotted or continuous road markings depending on the vertex group assigned to each edges in the main generator.
Custom Markings
The Custom Markings Generator is the one responsible for generating custom road markings. It generates markings along the edges of its base mesh.
It generates crosswalks, checkered, crosswalk bent and continuous road markings depending on the vertex group assigned to each edges in its own object.
Guardrails
The Guardrails Generator is the one responsible for generating guardrails. It generates markings along the edges of its base mesh.
3.1 LTS features a new guardrails generator that is faster and easier to use.
The legacy generator is meant to be deprecated.
Road Sides Instancing
The Road Sides Instancing Generator is the one responsible for turning the output from the main generator into a scattering of custom choosen objects along the sides of the road.
It generates these objects based on vertex groups assigned within the main generator.
3.1 LTS features alternative version of this generator, namely one based on curve drawing, which is much faster to use.
Only one will remain in future versions.
Road Details
The Road Details Generator is the one responsible for scattering road details onto the road.
Skidmarks
The Skidmarks Generator is the one responsible for generating tire marks along the edges of its base mesh.
Curbs
The Curbs Generator is the one responsible for generating race track curbs along the edges of its base mesh.
Vegetation
The Vegetation Scattering tool is the generator responsible for generating vegetation on the terrain. It needs the terrain output of the main generator to be fed to it in order to function properly.
It generates vegetation based on vertex weight painting on that very bit of terrain mesh.
3.1 LTS introduces a new scattering tool that is curve drawing based, which is much faster and easier to use.
The legacy vegetation scattering is meant to be deprecated in future versions.
Sidewalks
The Sidewalks Generator is the one responsible from creating sidewalks along the edges of its base mesh.
It is also meant to be deprecated in future versions for a better alternative.
