Changes

Almost all shaders inside SCS Game engine are using vertex colors. That's why it's very important how you set them.  If shader explicitly doesn't specify otherwise , then vertex colors with values 0.5 are actually neutral colors and won't change the look of resulting mesh inside game. If vertex colors are below 0.5 it will "darken" the model and what will be above 0.5 will result in "brighter" mesh.
