Environment API

The Environment API controls all global lighting and shadow behavior in Hardline.

This includes:

• Shadow color and strength
• Shadow cutoff and range
• Environment light color and intensity
• Additional light masks

This API does not control real Unity lighting. It controls how the Hardline environment system shades the scene.

---

Shadows

SetShadowColor(Color v)

GetShadowColor() → Color

Controls the global tint applied to all shadows.

---

SetShadowIntensity(float v)

GetShadowIntensity() → float

Multiplier applied to shadow strength.

Valid range: 0.0 – 2.0

Higher values produce darker shadows.

---

SetShadowClip(float v)

GetShadowClip() → float

Controls where shadow bands clip.

Valid range: 0.0 – 1.0

Higher values bigger, chunky shadows. This is at what darkness in the shadow sample we should cut out for the solid shadow.

E.g. Distance from a light source shadows are cancelled out.

---

SetShadowRangeMult(float v)

GetShadowRangeMult() → float

Scales how far from occlusion sources at which shadows are cancelled.

Valid range: 0.0 – 4.0

---

Environment Light

SetEnvironmentLightColor(Color v)

GetEnvironmentLightColor() → Color

Controls the ambient fill color applied to all materials.

---

SetEnvironmentLightIntensity(float v)

GetEnvironmentLightIntensity() → float

Controls how strong the environment light is.

Valid range: 0.0 – 2.0

---

SetEnvironmentLightInfluence(float v)

GetEnvironmentLightInfluence() → float

Controls how strongly lights cancel out environment lighting.

Valid range: 0.0 – 1.0

Higher values cancel out more of the environment light, useful for night-time or dark scenes, where lights should return visibility and color back to baseline.

---

Additional Lights

These are not real lights.
They are distance masks used to locally modify environment and shadow layers.

GetAdditionalLightCount() → int

Returns how many additional lights are currently active.

This is capped by:

StyleControllerEnvironment.MaxAdditionalLights

---

GetAdditionalLight(int index) → Vector4

Returns light data at the given slot.

The vector contains:

• xyz → world position
• w → range

Returns Vector4.zero if the index is invalid.

---

Synchronization

RequestImmediateLightSync()

Forces a rescan and upload of all additional lights.

Use this when:

• Lights are enabled or disabled
• Lights are moved
• The camera jumps large distances
