Nice one! What’s ideal about this solution is I don’t have to mess with any networking stuff, it’s all done in the shader which is exactly what I wanted 
I’m still confused as to what actual values the Vector nodes give out at times. Absolute World Position is just that right? The position of the pixel in world space? Screen Position still confused me somewhat, that’s a (assuming normalized) float2 from 0-1 in X and Y, corresponding to the pixels location on the screen right?
