Converting 3DS files to O2 light:
Let?s start:you have an 3ds file,now import in from 3DS to P3d:
3ds models have 1:10 scale,so just scale them 10 times bigger
ok,now it?s ok,but if you look to Buldozer u see somethnig is not allright:
yes,the shadows,but we?ll repair it...press CTRL+A(Select all) and that hit F5 and as you see now it?s look much better.
And dont forget to use Sharp Edges at the end ;)
