i dont think its reflection you are seeking. you are seeking a powerfull graphic shader to represent the split second flash. a specular flash. Ive played with the idea months back within the current shader at that state of development. and i think we should have a little somthing extra implemented over and above the current specular implementation. and it should definelty be very dependant on light direction. however whilst this was an observation method im sceptical about how often it could be used given how angle dependant it and weather permitting the function is. its more of a chance occurance leading to an outcome than a strategic method leading to a kill. because to use it strategically would involve already knowing where the enemy is located, theoretically.
