I did a pretty good example of this on one of my space maps by making the character a 3rd person model of a space ship and shrinking it, it did actually look and feel like the map was 10x bigger
so i presume that would work both ways
ahh here it is just found it its an oldie but shows the effect
Intel i5 4950 Quad core 3.3ghz AMD FX 6300 x6 cores 3.5ghz(unclocked)
8gb Ram 8gb Ram
AMD Radeon 7570 1gb AMD Radeon HD 6670 2gb
and a well fed mouse on a wheel
I only smile because i have absolutely no idea whats going on
