I have a "low poly" surface, where the color palette for polygons is low (e.g. 20 distinct colors). Is there a way to change the color (with a smooth transition) for all polygons painted with a certain color?
Maybe an analogy would be to smoothly make all polygons of a certain color transparent..
I have managed to get a 2D variant working: load a bitmap on a canvas and use a shader to change the color.
