This is my latest project im workin g on.It will be a part of a bigger scene.Materials isn’t at final stage.
I don’t know how can make realistic strings. I tried to do it with curves, but it don’t look very well.
As for the strings, I expect you will need to make a very small mesh with a cylinder with the wire winding around it for the heavy gauge strings and 3 cylinders for the 3 tops strings.
It depends how ‘heavy’ you string your guitar I suppose!
