Hello everybody,
I wanna know what is the best way to deal with refractions in comp preferably nuke.i want to know how to adjust the background in nuke without affecting the refractions. I watched arvid's video on this:https://youtu.be/PUJZQKXW67I .But it isn't clear to me on what to do if i dont have geometry or projections. What to do when you have just a image plane? What to do if you haven't decided the backplate yet or it has to change? i dont think that the refractions affect the alpha channel. How to deal with this. Any help would be really appreciated.Thanks in advance.
