I had a lot of emails recently asking about the car building method I use and several in particular about the use of splines. Not that I am real expert on the subject, but I figure that I would put together something that just outlines some basic steps for those Max users that are just getting started in car modelling. This a model of a Mclaren F1 that I created over the course of an evening in an attempt to show the spline/polyedit method that I prefer to use. The first step was to roughly trace out the spline curves from some blueprints. I kept the spline cage flairly simple and just framed out the major portions of the car. The next step was to apply a surface modifier with either of the following depending on how dense of mesh you like to work with : spline->surface->1 step->meshsmooth iteration=1->editmesh spline->surface->2 steps->editmesh Then comes the hard part of doing all the cutting, extruding, chamfering and edge flipping/hiding. If the model looks a bit off it is because I just eyeballed alot of the features from some reference photos. Normally I would try and match the curves,openings,etc to the blueprints while polyediting but that process would take a lot longer to do. As you can see I didn't get a chance to finish the model, but in its current state the mesh is around 60K polys with a meshsmooth iteration=2 applied. You shouldn't need to go above 2 iterations otherwise you would be better off adding cuts to the base mesh. Hope this has been of help to some of you :)
