Quote from DanielAragonim surprised it looks so good.not that i doubt your skills or anything which are obviously good, but you said the original hl2 buggy had 4k polies and this one has roughly half. tbh this one looks much smoother in places. the original looked downright boxy in some places.
The polycount will be about 5000 once I get it into HL2. Right now 3dsmax is only counting faces, not triangles.
