Hi Chris,

Thanks I managed to use lerp to interpolate between facial expressions (ie happy to sad would be lerp between an arc (for the lips) with a certain length, width and fill radian to another). I also managed to connect a slider which controls the level of interpolation (how happy or sad you want it to be). While this works for an interpolation between 2 states, my question is regarding how to do multiple states simulatenously? I want to have multiple sliders which allow a combination of interpolations. ie sliders for happy to sad, happy to angry, happy to disgust and you can be on 40% sad, 60% angry, 80% disgust and the lips adjust to interpolate a combination of the three interpolations. Appreciate your help/support!
