Hello.

I've been modelling this car for 3 days and I'm stuck after I do poly -> subd conversion (I'm a total newbie)

I followed almost the same precedure from https://deep.sitenest.net/tutorials/maya/car4/

pic 1. poly of my car. looks too square so decided to go for subd.

pic 2. wire frame.

So I converted to subd. And the result came out pretty bad.

pic 3. ugly fender.
user added image

Not only the fender isn't round but also look at that thing!
I figured out if I triangulate the fender, it becomes round but still, that thing doesn't dissapear.

pic 4. wire frame of the fender.

and another bad boy..

pic 5. head light.

I just want that part to be smooth.

pic 6. wire frame

so.... could somebody help me to flatten that thing?

Thank you for viewing this. user added image

btw, I also tried polygon -> smooth option.. and didn't work out well. Anyone know the reason?

could we see a wire of the poly befor you convert ? a close up of the problem area ? if you don't want to go back to polys with some undo's, you can put the subD in to poly proxy.. looks like you just have a vertix out of place..

It is hard to see why it turns so ugly without a lowpoly wireframe closeup of the area, but I'd wager a guess that you have 5-sided or more polygons. Keep it to quads as much as possible and only triangles where necessary and it will convert better to subd's and smooth way better with polysmooth too.

It would be a LOT smoother in polygons if you made the normals smooth. (EditPolys>Normals>Smooth/Harden options box) Set the value to smooth out the normals and press "ok." A big part of poly modeling is knowing how to mess with the normals correctly.

You can, of course, continue to persue sub-div's if you wish, but I really do think polys are easier.

You have way too many sides on those polygons. As I said, for clean results in subd or smooth you need 4 sided polygons. I see several places where you can weld (hold v for vertexsnap and drag 2 verts ontop of eachother, edit polygons -> merge vertices) vertices. Keep it clean and it will smooth clean. If you absolutely have to (which you will, in most complex models) you can use triangles. Hope this helps. If you need detail you need to cut using the split polygon tool. Your car looks really nice, but these principles will come back and haunt you if you don't do them correctly.

edit:
I don't think you're an idiot, I just wanted to be overly obvious and clear in what I meant.

insted of welding most of thoughs verts you can just delit them. 4 sides polys are def prefitable !!! remmeber to use the split poly tool on the fenders though.. you will need some edges to make the 4 sides polys there on the finders. so you can delit or weld the verts..

And I got another question.

how do you make door gaps in subd?
should I extraud face in poly? or is there a better way for it?

and in the above pic, there are little white dots everywhere. How would I fix that too?

Again, many thanks for viewing this.

I tweaked your pics to be smaller....should be about the same quality only now they are 800x600

try and keep them maximum 800x600....maybe run it through PS to get the filesize down as well.....every little bit helps

Hey I was in a good mood user added image

Good job so far btw user added image
