{% hint style="info" %}
The material requires 3 main maps in order to mimic a liquid-like shine\
\
**Alpha Mask Map** - This is the primary source of the color modifiers, dissolve, and opacity.**Normal Map and ReflectionTexture** - By sampling these two textures you mimic a fake specular behavior.
{% endhint %}

### Modifiers ![](/files/q78XB69Lr5UQOpKzAdfS) <a href="#id-7bi33pm0m2yr" id="id-7bi33pm0m2yr"></a>

{% hint style="info" %}
**NormalStrength** - Normal map intensity control\
**Power** - Alpha Mask exponent control used for lerping two colors\
**Softness** - Edge Softness

**SpecularPower** - Fake specular exponent control\
**SpecularValue** - Fake specular intensity multiplier

#### Particle Decal Renderer (NEW) <a href="#lsgwbpcouwvj" id="lsgwbpcouwvj"></a>

\- Can disable projection to Meshes using *ReceiveDecals* boolean.\
\- Uses Deferred Decal rendering. Supports PBR.

\- Reacts to lighting condition (LIT)

#### ![](/files/04bRXZckOc6XWfBmOVj1) <a href="#id-1nwz9ha7rnxf" id="id-1nwz9ha7rnxf"></a>

#### **Removing the Emissive**

By default the *M\_LiquidDecalBase* uses emissive channel for it’s color.\
In this case you may experience a glowy shading in dark light setting.

For you to utilize the lighting condition. You’ll need to make modification for the *M\_LiquidDecalBase.*

<figure><img src="/files/dsPSn3QNEacTVDQwuVpg" alt=""><figcaption></figcaption></figure>

As you can see, the color is connected to the EmissiveColor channel.

<figure><img src="/files/ER54lseNhAgddYLOaHUd" alt=""><figcaption></figcaption></figure>

Switch the connection to the *BaseColor.* Make sure to delete the *divide to EyeAdaptation*.

{% hint style="info" %}
You have to modify these parameters on the *MaterialInstance* to reduce the dark contrast shading.
{% endhint %}

Darkness: **1.5**\
NormalFlatness: **1.0**\
SecondaryColor: **FF001700**

#### Shader Based Projection (Legacy) <a href="#id-20t6jphuo9gk" id="id-20t6jphuo9gk"></a>

* *ReceiveDecals* boolean wont work
* Uses Translucent Rendering (Non PBR)
* A cheaper alternative if you don’t mind lighting conditions
* UNLIT

![](/files/nQkI7ZVMenWiFxsxTTYg)

* Automatically rotate based on the normal of the collision
* Exposed Param that you can modify to create desired splatter behavior
* *LifetimeMultiplier*
* *ScaleMultiplier*
* *SpawnCount*
* *VelocityMultiplier*

Attach *NS\_Dripping\_Dynamic* to desired bone/socket location.\
The emitter has a collision event that spawns splashes and splatters.\
Combine it with a decal component for an accumulation effect.

## Reducing Steep Angle Artifacts <mark style="color:red;">(UE 5.5 Deprecated)</mark>

Decal material instances derived from master materials such as `M_LiquidDecalBase` and `M_LiquidDecal_Puddle` have control to lessen the decal projections artifacts.
