Object Model: Shader.RemoveTextureLayer

Shader.RemoveTextureLayer

Introduced

v4.0

Description

Removes a texture layer from the container. If this container is the only owner of the layer, then the layer will be deleted from the scene, otherwise it is simply removed from this container (but still owned by other containers).

Tip: A Material can also be a texture layer container, and has the same set of related methods.

C# Syntax

Shader.RemoveTextureLayer( Object in_varLayerToRemove );

Scripting Syntax

Shader.RemoveTextureLayer( Layer );

Parameters

Parameter	Type	Description
Layer	TextureLayer or String	Texture layer to remove from this container.

Examples

1. JScript Example

/*
        This JScript example shows creating texture layers on
        a shader, plus enumerating and removing them.
*/
oRoot = ActiveProject.ActiveScene.Root;
oSph = oRoot.AddGeometry( "Sphere", "MeshSurface" );
oMat = oSph.AddMaterial( "Phong" );
oPhong = oMat.Shaders(0);
// Add a layer at the end (since there are no others the "After"
// flag is irrelevant).
oLayers = new Array(3);
oLayers[0] = oPhong.CreateTextureLayer( "B", true );
// Add another layer before the other one.
oLayers[1] = oPhong.CreateTextureLayer( "A", false, oLayers[0] );
// Create a third layer at the very start.
oLayers[2] = oPhong.CreateTextureLayer( "base", false );
Application.LogMessage( "Created " + oPhong.TextureLayers.Count + " layers." );
for ( i = 0; i < oPhong.TextureLayers.Count; i++ )
{
        oLayer = oPhong.TextureLayers(i);
        Application.LogMessage( (i+1) + ": " + oLayer );
}
oPhong.RemoveTextureLayer( oLayers[1] );
oPhong.RemoveTextureLayer( oPhong.FullName + "." + oLayers[2].Name );
count = oPhong.TextureLayers.Count;
Application.LogMessage( "Only " + count + " remains after removal." );
for ( i = 0; i < count; i++ )
{
        Application.LogMessage( (i+1) + ": " + oPhong.TextureLayers.Item(i) );
}
// This example should log something like:
//INFO : "Created 3 layers."
//INFO : "1: sphere.Material.Phong.base"
//INFO : "2: sphere.Material.Phong.A"
//INFO : "3: sphere.Material.Phong.B"
//INFO : "Only 1 remains after removal."
//INFO : "1: sphere.Material.Phong.B"
