ROUND SHAPES WITH HARD EDGES.....where do I put the support lines?

ratatatatat

Hi guys. So, this has been an issue I have been avoiding for a while now. Everytime I create an object that has a combination of curves and straight edges, I have a whole world of trouble getting the hard edges I want to not effect the smoothness of the rounded areas. A picture is the best description:)




where do I put the support edges, so that the rounded area does not get effected by the support edges created to define the hard edges of the flat areas?

I'd love to know, it's been so long that I have avoided these kinds of shapes.

Thanks

Try the double turbosmooth method.Or use a lot more segments/sides on the "basemesh".

'double turbosmooth' whaa? You mean just adding 2 iterations?

I tried with a more dense base mesh but it got out of hand how messy it was getting. Trying to retop for a low poly is unrealistic. This is for a shape like a r2-d2 helmet, with a slot cut out of the top:P

No, he means this method:

ahhhh. that's totally new information for me:P Thanks a ton guys that pretty much exactly what I was after.

Here's a little magic trick (image below).

Typical lip geometry will create the artifact seen on the left row, because on the left side of the object, geometry row A is affected by geometry row B, while on the right side, A remains unaffected.

What you do is build the control loop lip as a continuation of row B, with the same angles.

This still creates an artifact, but a less significant one. You can leave it as it is, or combine it with other methods like slightly more geometry, to suit your needs.

Observe that the softer the transition, the less visible the artifact:

AWESOME...this is even better. Having ontrol over the edges is more what I needed, so this method is perfect. I just couldn't for the life of me work my head around it this time.
Heres an example of what I was after,using the method WarrenM and Obscura posted



Low poly is just a 1 minute job, quite low, with symmetry and added the turbosmoothes and smooth groups and Max did the rest.

Both methods RULE!

Thanks so much for the quick replies.

Never thought about this, great tip perna

yup

looks great :thumbup:

A similar approach was used to build this:

@Illusions_Nice work man. I used your topo for my asset as it was almost the same. However, there is a flat area that houses the screw on the side of the dome that I stopped tinkering with because I just couldn't get the pinching to stop, I could only make it less noticeable.
Heres some images of the model it's on. As you can see, the piece with the shapes I initially enquired about is TINY (the piece that joins the aerial to the aerial housing) and this will be as close as anyone will ever get so I decided to stop refining after I wasted an hour. It was a learning experience:P

p.s. the piece looks a bit square in the screenshot but it's not, it's pretty spot on:)

so I had a look at the reference some more and noticed there was more detail in the piece. 5 minutes later, after adding more surface detail, this is pretty much perfect.

thanks folks
