View Full Version : Can you spot what I'm missing? (lathing)

Firstly, thanks for having a look at this message :)

I am trying to follow the tutorial #6 from the Max4 Tutorials file. In which one is to model a Low-Polygon Character (Tubby).
And although I've found it to be pretty straight forward for the most part, somehow I ended up with a different result.
It involves using the "Lathe" modifier to create the head of Tubby. I am including an excerpt from the beggining of the tutorial so that you can see the steps one is to follow, along with an image from the same tutorial showing what you are supposed to get, and an image from my following to show the different result I get.
I hope someone here can spot the reason why I end up with many more horizontal segments.

The tutorial excerpt
Starting Tubby's Head
For Tubby's head, instead of a box, you'll start with a spline line and then lathe it to produce the initial shape. You could start with a sphere and adjust the vertices, but using a spline provides more control from the start, thus producing faster results.

Creating the head shape

On the Create panel, click the Shapes button to access the Object Type rollout for Shape objects.

Click the Line button.

The button highlights; you can now draw a spline curve in a viewport. Keep the default settings.

In the Front viewport, above the neck, draw a spline that looks like the right side of a letter B.

This is an approximate shape of the side profile of Tubby's head.

Around the eye area, make two close-set vertices above and below where the eye will go. Around the mouth, place one segment about where the mouth will be. Use seven or eight vertices to define each bump in the curve, as shown.

By the way, the image posted in the previous message belongs to the tutorial too.

The following steps are also part of the tutorial excerpt:

4. Click to enter each point, and right-click when done to exit Line creation mode.

5. Open the Modify panel, and in the Modifier List > Patch/Spline Editing section, add a Lathe modifier.

The Lathe modifier spins a curve around an axis to create a rounded shape. This is similar to a real-world lathe in woodworking. By default it spins around the center of the spline, which creates an odd-looking shape.

6. On the Parameters rollout > Align group, click the Min button.

This tells Lathe to use the left side of the spline. You should see something like a head shape.

(continue in next message...)

One more step:

7. Still on the Parameters rollout, set Segments to 12.

The reason for using a lower number of segments is that you will be adding MeshSmooth to the model, as with the body. Using 12 segments gives you enough detail to get started.
End of excerpt -----------------------------------------------------

There are a total of 19 steps, but they are not necessary to make my point.

See the image included in this message. This is the spline I lathed for the head. As you can see it has a lot more horizontal segments! Why? I also followed step #7.

Thanks in advance for your patience and help :)

hmmm

could it be that your lathe output is set to 'patch' and not mesh

it seems patch naturally adds a lot more segments?

looks like the spline interpulation is higher than the tutorial.
in the modify panel select the spline, in the interpulation rollout set the steps to 0, and make sure the "optimize" checkbox is checked.

hOpe this helps,
