I bought a model of a character that has about 8 different materials to it. In LE2 as long as the material files the model was expecting were in the directory this all worked. In LE3 when I import the model and a material, then place an instance of the model in the scene, and drag the material over what should be the correct part of the model, it applies the material to the entire model. How can I use this model in Leadwerks 3?
