Removing or Disabling Style Features

This document explains how to disable or remove specific Hardline visual systems when they are not needed for a project.

Hardline is built from several independent full-screen and material-driven systems:

  • Outlines
  • Skybox
  • Environment lighting and shadows

Some of these are controlled by URP render features, and others are controlled by style values.

They are disabled in different ways.

Full-Screen Style Features

Hardline uses URP Renderer Features for its full-screen passes.

These features live on the Hardline render pipeline asset:

Assets/SmnStyleHardline/Core/Runtime/Graphics/URPSettings/SSH_RPAsset

Select this asset in the Project window to see the renderer configuration.

In the Inspector you will see a list of Renderer Features.

The important ones are:

  • Screen Space Shadows
  • SSH Outline Color
  • SSH Outline Geo
  • SSH Skybox

Each of these corresponds to a full-screen render pass.

Screen Space Shadows

This feature is required for:

  • Hardline shadow tinting
  • Environment shadow masking
  • Additional light shadow interaction

It provides the depth-based shadow buffer used by Hardline materials.

Do not disable this unless you are removing all environment shadow behavior.

SSH Outline Color

This is the color-based outline pass.

It generates outlines from:

  • Color contrast
  • Screen-space edges

If this feature is disabled:

  • All color outlines disappear
  • The Color Outline section in the style has no effect

SSH Outline Geo

This is the geometry-based outline pass.

It generates outlines from:

  • Surface normals
  • Depth discontinuities

If this feature is disabled:

  • All geometry outlines disappear
  • The Geo Outline section in the style has no effect

SSH Skybox

This is the procedural Hardline skybox.

It renders:

  • Gradient bands
  • Dual-tone sky colors
  • Procedural starfield

If this feature is disabled:

  • The Hardline skybox will not render
  • The scene will fall back to Unity’s normal skybox or camera clear color
  • All Skybox style values become inactive

Disabling Outlines

To remove outlines completely:

  1. Select SSH_RPAsset

  2. In the Renderer Features list, disable or remove:

  • SSH Outline Color
  • SSH Outline Geo

No changes to materials or style values are required.

The outline API and inspector will still exist, but they will no longer render anything.

Disabling the Hardline Skybox

To remove the procedural skybox:

  1. Select SSH_RPAsset

  2. Disable or remove:

  • SSH Skybox

The scene will then use:

  • The Camera background color, or
  • A standard Unity skybox

The Hardline skybox style controls will no longer affect rendering.

Environment Lighting and Shadows

Environment lighting and shadows are not a full-screen feature.

They are evaluated inside every Hardline material.

This means they cannot be disabled by removing a renderer feature.

Instead, they are controlled through style values.

Disabling Environment Light

To remove ambient environment lighting:

In the SSHStyleManager inspector:

Environment → Environment Light → Light Intensity

Set it to: 0

This removes all global ambient lighting from the scene.

Materials will render using only their base and accent colors.

Disabling Environment Shadows

To remove global shadowing:

In the SSHStyleManager inspector:

Environment → Shadows → Shadow Intensity

Set it to: 0

This disables the shadow layer entirely.

Disabling All Environment Influence

To make the scene ignore the environment system:

Set:

Environment → Environment Light → Light Intensity = 0

Environment → Shadows → Shadow Intensity = 0

This leaves:

  • Skybox (if enabled)
  • Outlines (if enabled)

but removes all lighting and shadow modulation from materials.

Material-Level Overrides

Even when environment lighting and shadows are enabled globally, individual materials can opt out.

Hardline shaders expose:

  • Environment_Light_Influence
  • Environment_Shadow_Influence

Setting these to zero on a material makes that object ignore:

  • Environment lighting
  • Shadow tinting

This is used for:

  • Fire
  • UI meshes
  • Particles
  • Glowing objects
  • Effects

Full-screen systems live in the URP Renderer.
Lighting systems live in the Style and Materials.

They are intentionally separated so each part can be removed cleanly without breaking the rest of the pipeline.
