Yes an no. Damascus steel looks different than Beskar. The former has a lot of ”jaggies” along the waves, and usually more circular patterns, while Beskar has smooth waves. Beskar also seems to have more light-dark tonal variations in the waves.What about the. marbling effect, is it going to look like Damascus steel?
So, it will look like this (but with real metal shine underneath, not spray paint):
The one on the left is a screencap, the two on the right are my prototypes, each with a different silver spray paint (dark/light) under the pattern. I'm not absolutely sure yet which screen pattern I'm going with, but probably the one above, since that's the very first bar we saw in the show.
