If you are going to keep these up, you might as well flat shade the models...
Don't listen to comments like these. Flatshading doesn't automatically make things better. Almost all default blockland models use some for of smoothshading in them. The difference is that these are just crappy models that don't fit in either way. This is one of those add-ons released just so the creator can feel proud of people using it. A dish out crap kind of deal hoping to achieve positive reviews. Like an RTB colorset, I bet more than half of the authors of colorsets don't even use their own. I mean seriously, when was the last time anyone used props?
Here's a tip, make them into playertypes or something, then people might use them.
