Glass experiments

Just some small experiments with some glass and refractions using a water texture I made. (No caustics though)

With the water texture (and bumpmapped):

Just some simple UV-mapping practice (and more glass (w/out water texture)):

Well, it looks a bit unrealistic, especially the first seems to be hollow.
What refraction index is the material set to? Notice that water has 1.3.
Maybe it only seems so because it’s not common to see a water cube on the table :wink:

But the texture looks good.
