What is the purpose of the Material Out Node, I was searching within the documentation and couldn't find the information, sorry if I by passed ?

Hi,
output nodes are useful to create the necessary output pins in node-graph groupded nodes.
Let’s say that you have a material network composed by several nodes, if you group them when the material is already connected, the new group will have the correct Material Output node connected to the material node.
If the material is not already connected, when grouped, the resulting group node will have no output pins, and you have to manually create a Matetial Output node connected to material inside the group node, to see the desired pin in the bottom of group, and correctly use or export the material.
The same workflow can be used to group different type of nodes, with differnt output pins type, to better organize your scene.

I don't understand ?

What do you mean if the material is not already connected when grouped; with no output pins ?

Place 2 material nodes, select both, right click and create a group. Double click to enter the group. Now place your Material Out node and go back to the main scene graph (select the 'Scene' tab). Now watch, you can now link the Material Out of this group to geometry.

When you say two material nodes, you mean; diffuse, spec etc; correct ?

Yes!

Thanks.
