Making things transparent was surprisingly easy.
It had always bugged me how all these alpha bits were always opaque in SY's conversions. I tried to do it before but somehow never could. I found a tutorial now, it has like 4 steps. It isn't perfect (this is a Cities XL model ported to Cities:Skylines and then to TS4 so the textures are compressed to hell) but it's sooo much better than having a square ruining the model.
Also I turned Latin characters into Simlish. (Back when I first tried, like 2 years ago)
I'm back in S4S slimming down my CC folder so it doesn't take 30 mins to load a neigborhood lol. SY has some massively unoptimized models I'm really considering throwing out, but then I'll have nothing to place instead.
(Some may be easier than others though)
This one may take me forever.
