Is very easy to make this glass. Just assign a mia x material and choose one of the glass presets, glass solid in this case, and tune it as you like. Take care because if you put several pieces of glass behind other you will have to rise the max trace depth number or you will get dark areas.


I have been learning something about gamma correction, and suposedly the problem is that the gamma is applied two times, one in the lens shader, and another one in the texture, and then we have to use a gamma correction node.

I have just done that a moment ago and i was unable to get a better picture even trying the 0.45 thing (the number you have to multiply the given gamma), but im still a noob in gamma correction. Ill keep trying.
