could a mod please move this topic to the WIP section? this is not a 3DSMax issue at all
first of all, looking at your model i can see 1 big error: the whole mesh is one piece. this is a common big mistake for beginners (i have done it too
) look at the real car. you will notice that the hood, fender and bumper are all different and independent parts. the same counts for your model. work with a number of different objects.
also you should study up on how turbosmooth/meshsmooth actually works. if you manage to understand it, then modeling the mesh and getting what you want to will eventually become easier. if you don't get the hang of it, nevermind you can still just try around, but it will take a lot longer
second golden rule
: always use quads if you are doing a high poly model, like the one you are doing! if you simply cannot work around a tri, then you should see how the mesh needs to be organised so you don't see it in the end.
n-gons and tris give very bat smoothing results. it has to do with the way turbo/meshsmooth works. it's not utterly important to know why the software works that way........ just keep in mind: always use quads
with these first things in mind, you should look at your model again, and i am sure you will be able to figure out what is going so horribly wrong
