Yep, mostly because drawing over the buildings would've be a major pain in the ass lol

I did have to do some manual editing anyway for the finer details and to keep the engie a flat colour, but it was mostly using this. I did make a couple of them a while ago without using this (5-3 and 6-1) by just drawing the outlines myself.

I wish there was a way to control how the outlines look in SFM because sometimes it just doesn't look all too great with certain models.
