I'm not familiar with Busou Shinki I'll have to swing by your channel to see what your talking about.
Unless you're in the anime realm I wouldn't expect anybody, yet I still do mention anime things because of Google. I'm not saying this bit in a rude way, just that I'd expect people to get curious to Google to see the basicness of things. My bad.... Late at night posting does that to me.
Also, your way of handling clothing dyeing is interesting. I support any form of customization. editNPC height would also work, yet having a slider bar for height may work? The scale sliders could work here for NPC heights in the 'editnpc' or whatever the option is now. It's been awhile.
I would really love walking into a living cityscape, even if it's dummy npcs. That be awesome.
