okay, i remember seeing a thread about how you can get that nice air-rippling effect from fire using a shader (i believe) where ti would warp and distort the screen using normal maps as the driving force…
i was wondering, is this kind of shader capable of creating air-rippling effects if it is not facing the screen to the point where you’d be able to make effects like you see in the Force Unleashed?
if this has already been done, does this need pro or can the standard free version use this? (asking since my pro-trial has already expired and if i can inplement that sort of effect driven by normal maps for my own game, it would really add the pizazz)
Yes, that project uses render texture. As far as I am aware, there is no possible way to achieve this effect without render textures. So Unity Pro is required for such effects.
