TextureLayerPort
v4.0
The TextureLayerPort is an object used to describe which
specific shader and material parameters a TextureLayer affects. Like shader
connections, they indicate what shader ports are being driven by
the layer.
The port has a few properties which describe how the layer affects
a single shading parameter, generally these are used to modify the
layer's settings in a port-specific way, for example by inverting
or scaling the overall effect. A layer may be set up to blend its
color by 50% with the layer beneath it. However, that layer's the
ambient port effect may only be 25% whereas the diffuse port
contribution could be set to 100%.
/*
This example shows creation of texture layer ports,
plus enumerating and removing them.
