I used the GLSL export plugin from Blender in order to use with the game engine as a material, but I can't seem to use it properly.
I tried following the information provided by the Leadwerks wiki, but I'm not a programmer, so I don't know how to properly call the .vert and .frag files into Leadwerks. Any indication of what to do would be greatly appreciated!
