This parameter can be used to add a "pearlescent" effect to the Standard material type.

 

-   ##### Use Pearl Effect

    This can be used to enable/disable the pearlescent effect of a material.

 

-   ##### Color Shift

    Use this value to adjust the amount of shift from the base color that the pearlescent effect will produce.

    This value determine how the decal material is blended with the background. A value of 0 means the background material's color component is used. A value of 1 means the decal material's color component is used. A value between 0 and 1 will blend the two values. The components are linearly interpolated.

A value of 1 means the decal material's roughness component is used. A value between 0 and 1 will blend the two values. The components are linearly interpolated.

 

-   ##### Metal

    This value determine how the decal material is blended with the background. A value of 0 means the background material's metal component is used. A value of 1 means the decal material's metal component is used. A value between 0 and 1 will blend the two values. The components are linearly interpolated.

 

-   ##### Occlusion

A value of 1 means the decal material's occlusion component multiplied with the background one is used. A value between 0 and 1 will blend the two values. The components are linearly interpolated.

-   ##### Normal Mode - Tangent / Override

    This parameter permits you to control the way surface normals will be generated based on the given value, where:

    -   0 - The mesh normal will be that of the surface the geodecal mesh is covering
    -   1 - The mesh normal will be that of the geodecal mesh itself
    -   &gt; 0, &lt; 1 - The mesh normal will be an interpolated normal between that of the original mesh and the geodecal mesh.

 

-   ##### Render On ClearCoat (3DS Max) / Render Under Clearcoat (Blender)

    When this is checked in **3DS Max**, the material will be rendered *over* the [ClearCoat](flightsim-materials/#clearcoat) layer instead of under it. When this is checked in **Blender**, the material will be rendered *under* the [ClearCoat](flightsim-materials/#clearcoat) layer instead of over it.

 

-   ##### Decal Channel Masks

    This section is used to determine the render channels which the Decal material will use in the simulation. You can check 1 or more of the boxes, but note that if you *un-check* all options, **the decal will be invisible in the simulation**. The options available are as follows:

    -   **Scenery Channel** - The decal material will render on scenery objects.
    -   **Terrain Channel** - The decal material will render on terrain.
    -   **SimObject Channel** - The decal material will render on SimObjects.

For more information please see here: [Insect Splatter](../../modeling/aircraft/airframe/windshield-and-windows/#insect-splatter).  

{{< image-center

For more information please see here: [Insect Splatter](../../modeling/aircraft/airframe/windshield-and-windows/#insect-splatter).  
    Adjusting the slider value will adjust the alpha mask application so you can see the insects "appear" on the windshield, as shown in the image below (note the image has been tone adjusted to make it more obvious what is happening):

-   ##### Rain Drop Tiling

    This value can be used to adjust the size of the raindrops on the windshield. When setting this value be aware that higher values will create smaller raindrops, and lower values will create bigger raindrops. Only valid when [Recieve Rain](#recieve-rain) is enabled.

 

-   ##### Rain On Backface

    This option determines on which side of the glass the rain effect will be rendered. This is disabled by default - rain will be rendered on the front face - and is generally only required if you see the raindrops move in the wrong direction to the current airflow (from wind or movement). Only valid when [Recieve Rain](#recieve-rain) is enabled.

-   ##### Melt Sys

    If your aircraft is equipped with a **melt system** to remove ice accretions (ie: a series of chemical sprays that can be activated to remove the ice from parts of the aircraft like the leading-edges, stabiliser, etc...) then this should be set to 1.

    If your material does not require two separate roughness maps - as would be the case, for example, with a varnished carbon part - and you simply need to apply a layer of clearcoat while keeping the roughness information of your base material, you can check this option. When checked, it will disable the [Clearcoat Colour (RGB) ClearCoat Roughness (A)](flightsim-material-textures/#clear-coat-amount) texture slot, and will use the roughness from the material's [Occlusion(R) Roughness(G) Metallic(B)](flightsim-material-textures/#occlusionr-roughnessg-metallicb) texture map. This will also enable the [Base Roughness](#base-roughness) modifier to be edited.
