ShaderFX has always supported Group Nodes, which are a collection of nodes combined together into a single, easier to use Group node.

However to make new Group Nodes, artists were required to use Maxscript. This is no longer required in ShaderFX 3.0.

Artists can now create new Group Nodes with an easy to use interface without the need for any scripting.

Group Nodes are 100% compatible with older Group Nodes and can easily be shared between team members.
