alright.. there is a car tutorial that is coming.. sometime.. i don' t know when. As for making a car.. there are two main ways:

POLY MODELING - CONVERT TO SUB-D

Pros
really smooth
You can get the panels in one piece
polys are easy on the comp
easy to manipulate surface (edit points are on the surface)
easy to texture

cons
takes a while to get a "finished" look to it
a lot of dividing the polygon.
really hard to get the curve to be really smooth

NURBS

pros
You can get a "finished" looking product really fast
easy to make holes in the surface (great for hoods, and front ends)

Cons
Birail can be a really big pain in the a$$
the surfaces are really hard to stich together (hard to get pannels in one piece)
pain to texture
edit points aren't on the surface

Now.. I did my car in nurbs... and i don't really know why... i just wanted to try new things, and nurbs are fast. If you look in the wip (honda CRX) you can see a nurbs car model.

Currently, i am working on the crx and also the s2000. The s2000 is being done in polys, then being converted to sub-d's. So far.. i am preferring to use polys.. mainly for texturing, and the panels can be made in one piece.

If you need any help, just pm me or else contact me at snowboarderCF on AIm.

Have Fun
