## BlendInTextureLayers

### Introduced

v4.0

### Description

Locates all the default texture ports (connection points) on the immediate shaders attached to the given objects. Creates layers with the requested presets, and adds these layers on the located ports.

### Scripting Syntax

    oReturn = BlendInTextureLayers( [PresetNames], [InputObjs], [SharedMatAction], [NotifyNoResult], [Mode], [Ambient], [Diffuse], [Transparency], [Reflection] );

### Return Value

Returns the layers created as an XSICollection. If the value of Mode is siReplaceNoBlend, the first preset is returned as a shader rather than a layer.

### Parameters

Parameter | Type | Description
--- | --- | ---
PresetNames | String | Shader Presets corresponding to the shaders and/or images you want to layer Default Value: "Image"
InputObjs | String | List of objects to search for default texture connection points Default Value: Current selection
SharedMatAction | Integer | Make shared materials local? Note: If "2" or "3" is used, a pop up dialog appears prompting the user to answer (0=No or 1=Yes). When the logged command is replayed, if "2" was used the command will automatically answer yes or no depending on the user's response. If "3" was used, the pop up dialog will reappear. Default Value: 2 (Ask Beginner User)
Possible Values: | Description:
0 | No
1 | Yes
2 | Ask beginner user
3 | Ask advanced user
NotifyNoResult | Boolean | True to notify user if no presets created. Default Value: False (no notification)
Mode | siBlendInTextureLayersModes | Method for blending in the new presets Default Value: siBlendInTextureLayers (no replacement)
Ambient | Boolean | If true, blend in to the ambient port (if present) Default Value: True (apply to ambient)
Diffuse | Boolean | If true, blend in to the diffuse port (if present) Default Value: True (apply to diffuse)
Transparency | Boolean | If true, blend in to the transparency port (if present) Default Value: false (don't apply to transparency)
Reflection | Boolean | If true, blend in to the reflection port (if present) Default Value: false (don't apply to reflection)

### Examples

#### VBScript Example

    '

    ' This example demonstrates how to apply blended shaders to all texture ports on a

    ' cube. It also shows how to access the shader information both from the collection

    ' returned by BlendInTextureLayers and through the object's material.

    '

    NewScene , false

    ' Create a default cube

    Set oBox = ActiveSceneRoot.AddGeometry( "Cube", "MeshSurface" )

    ' Apply Cloud and Gradient presets on all texture ports

    Set oLayers = BlendInTextureLayers( "Cloud,Gradient", oBox, 1, False, False )

    ' At this point you will also see a Multiple Property Sets page pop up for the shaders.

    ' Now display the name of the created shaders:

    For Each oLayer In oLayers

    	Set oShader = SIGetShaderOnCnxPoint( oLayer & ".color" )

    	Application.LogMessage oLayer.Name & " created with shader " & oShader.Name

    Next

    ' View the results in a rendered frame. (The colors appear quite smooth.)

    RenderPasses oDefPass, 1, 1

    ' Set the mode of the Gradient to "Darken":

    SetValue oBox.Material.Shaders( "Phong" ) & ".Gradient_Layer.mode", 8

    ' View the results in a rendered frame. (Now the colors seem to be quite mottled.)

    RenderPasses oDefPass, 1, 1

    ' Output of above script:

    'INFO : "Cloud_Layer created with shader Cloud"

    'INFO : "Gradient_Layer created with shader Gradient"
