Stormz shows how to create materials that change based on object-orientation.

 You may have seen demonstrations that show how game engines can create materials that can change based on the orientation of the object on which you place them. It’s an excellent system for quickly putting moss on rocks and trees, trees on the sides of hills and mountains, snow on the flat surfaces, and not the slopes. Some DCC render engines also let you create these kinds of dynamic materials, like Redshift.

Materials That Change Based Orientation.

A new tutorial from Stormx shows how you can use the Redshift State Node to create materials that will change based on the object’s orientation. The example is placing moss on a rock. The setup is an easy one and includes a way to break up the moss to look more natural.
