I am trying to animate a 3d model of a head for my father’s research presentation. I’ve modeled the head and created a few different test textures (I just wanted to see if I could get everything working before I spent time making them look good) to highlight different regions of the head (Red=Frontal,Green=Around the Eye, etc). The rendered pictures are shown below. However, I cannot figure out how to have the different textures appear and disappear in the BGE based on user input. Essentially I want to have the Frontal texture appear after a left click and then have it disappear and the Around the Eye texture appear when the left mouse button is clicked again. Can anyone help me out with a way in which I can do this?
Also, there are no licensing issues involved with using this in my dad’s presentation are there?
