Nice tutorial, just a quick note: It isn't necessary to have Photoshop CS5 or above, I have CS2 and it can do what's described here. Older versions back to at least Photoshop 6, which is my oldest PC version, can do it except that pre-CS versions don't have the 'Filter Gallery', filters are chosen from the Filter menu instead.
I know this is three years later, but GIMP does not have a distort glass filter. Gimp users have to do some major work in order to do a glass effect. I am thinking gimp users may not "have" to do this step. Since most frames in TS4 game with a "glassie look glare". Am I right?
GIMP has a very handy "oilify" filter under artistic. It mimics the texture of the paintings in Sims 4 very well. I'd agree though that a glass effect would be totally optional, especially since paintings frequently aren't displayed behind glass.
