Linking Nodes

Inputs are black when there is no connection. They are white when another node is plugged in. Also, when your material contains more than two different types of surface root nodes (such as a PoserSurface node and a Physical Surface node), connections will gray out when you try to connect a node type that is “invalid” for that input.

Input connections will become dimmed when you try to connect a node to an input that is not valid.

After creating a node, you may need to link it to an input on another node. This is accomplished in one of three ways:

• Direct Link: Click the output of the node you wish to link (1) and drag the cursor over the node or shader input you wish to link to (2). Release the mouse button to complete the link.

Attaching a new node to the root node.

• Moving Existing Links: To move a link from one node to another, click the input you want to unlink (1) and drag the cursor off the node. Place the cursor over the new node you wish to link (2) and release the mouse button.

Relinking nodes.

• Clicking and dragging: Click the input you wish to connect to (1) and drag. A node connection line follows your cursor. When you release the mouse button, the New Node menu appears (2), allowing you to create a new node whose output is pre-connected to your selected input.

Adding a new node to a root node input.

You can link a node to as many other nodes as you wish and each node input can be linked to as many input nodes as you wish.
