### Texture Samplers \

{% 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 ![](https://2172137675-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FIDY48Kh4vjaW2sp9MS3a%2Fuploads%2FV3sqNvuVMj0uAMT1OuuD%2F4.png?alt=media) {% 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 {% endhint %}

Power: 2 | Softness: 0.0 | SpecularPower: 4 | SpecularValue: 50

Supports PBR. \- Reacts to lighting condition (LIT) ![](https://2172137675-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FIDY48Kh4vjaW2sp9MS3a%2Fuploads%2FHZ9OxA0ZT9rtlTV5GF0t%2F13.png?alt=media) #### ![](https://2172137675-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FIDY48Kh4vjaW2sp9MS3a%2Fuploads%2FRhnUI4A7gpfoNjGWpZDl%2F14.png?alt=media) #### **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.*

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

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) * *ReceiveDecals* boolean wont work * Uses Translucent Rendering (Non PBR) * A cheaper alternative if you don’t mind lighting conditions * UNLIT ![](https://2172137675-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FIDY48Kh4vjaW2sp9MS3a%2Fuploads%2FQbzQLLFGAofAU3RWa9vG%2F18.png?alt=media) ![](https://2172137675-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FIDY48Kh4vjaW2sp9MS3a%2Fuploads%2FkRsyAhyxNhKRkMdn6JcA%2F19.png?alt=media) * Automatically rotate based on the normal of the collision * Exposed Param that you can modify to create desired splatter behavior * *LifetimeMultiplier* * *ScaleMultiplier* * *SpawnCount* * *VelocityMultiplier* ### Artery/Dripping ### ![](https://2172137675-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FIDY48Kh4vjaW2sp9MS3a%2Fuploads%2FPNEwDkS02Y808TatBIRV%2F20.png?alt=media) *** ## Shader Controls

Build up animation for the puddles via Dissolve Function

*** ## Demos ### Use Case - Blood Linger and Accumulation

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.

{% hint style="info" %} Use a curve to modify the timing in order to match blood-dripping behavior. Then use the value to drive the *Dissolve* parameter. {% endhint %}

{% hint style="info" %} You can check more demos by going to this map. **Showroom\_Demo** While on this map, just simply play the Level Sequence. {% endhint %}

*** ## Affect by DOF

Still inside the LiquidBase (Master Material)

On the left side details panel. Find **TranslucencyPass** and Change to **Before DOF.** ## Reducing Steep Angle Artifacts (UE 5.5 Deprecated) Decal material instances derived from master materials such as `M_LiquidDecalBase` and `M_LiquidDecal_Puddle` have control to lessen the decal projections artifacts.

## 5.5 New DBuffer Implementation

Go to Mannequin master material

\ Check Decal Response (DBuffer) to make sure it is Color, Normal, Roughness.

Feed DBuffer(BaseColor) with this formula

For Roughness

For Normal (1st)

For Normal(2nd)
