Surprisingly there's a two very simple techniques to remedy LBP's low resolution sticker quality. First thing which everyone always seems to forget is that you have to zoom up really close to the object you plan on turning into a sticker. This is because you capture much more the object itself rather then the area surrounding it. Second technique involves taking multiple pictures of the object in different increments rather then taking a single picture. This results in REALLY high resolution creations even though it's marginally more taxing on thermo, you saw this with my Stonehenge-esque Railgun during the Cydaria fiasco even though It wasn't as refined as it could've been since I was only experimenting with sticker art at the time. It's the same technique I use on my StA-01 Volkenmeir MBT and StROLM-15K Draken Tank Destroyer. Each are around 3-5 stickers each, making them way more thermo friendly compared to those wasteful Panther 1A3's :^)
It also streamlines the creation process. I've been pumping out vehicles faster then I can think of edgy pseudo-German names for them.
