These examples of material change GUI's use the VR Vive controllers to initiate the selection of the materials and the selection of the material that the user is changing to. I didn't manage to find an example of a material change GUI which was controlled by the leap motion tracked hands. I did find a GUI which was controlled by the leap motion hands but the unity asset did not work with the unity gesture section pack that is currently in the scene of the project. The package here was built for the original unity core and Orion. Because of this is makes the project crash. I will now try to use object activation to make the GUI appear and select objects within the GUI on trigger with the leap motion hands in my project.
