For this tutorial it is expected that you have already followed the instructions in the tutorial Modeling a Pumpkin in Hexagon.

Step 1: Import pumpkin_6.obj and draw the outlines for the eyes and mouth

In the front view, click “File”, click “Import” and import pumpkin_6.obj

It is easier to add the Halloween face to pumpkin_6.obj because it is a pure polygonal file

with no smoothing. Adding a Halloween face to a hexagon file with smoothing can be a nightmare to modelers as you will find that the edges you add by tessellating are no longer straight so you cannot get the signature triangular eyes of a Halloween pumpkin :-) You can use Boolean method to cut out the eyes and mouth but this can complicate the mesh by adding a lot of vertices.

The following figure shows the guidelines of the eyes and mouth of my pumpkin. I made them by using the facet tools (click “Tools” in the menu bar, then click “Vertex modeling”, then “Facet”), with grid snap on (click “Display” in the menu bar, then “Sanp”), and with a bit of scaling.


I mark the guidelines onto the pumpkin mainly by using “Tessellate” (second icon of the drop down menu after clicking “Free Tessellate” icon at the “Vertex modeling” toolbar), which adds edges by joining any two vertices or edges; and “Connect” on the “Vertex Modeling” toolbar, which adds edges by joining two vertices of the same polygon. I mark the guidelines by joining vertices because this will not produce new vertices so as not to complicate the model mesh (although you might sometimes add a few vertices using “Tessellate” as it does not automatically snap to existent vertices).

The following figure is pumpkin_6.obj with guidelines for the mouth and eyes marked on.


Step 2: Carve the eyes and the mouth

Press F2 to change to “Select Faces” mode. Select the faces making up the eyes and mouth as the following figure shows (the highlighted faces) and click “Fast Extrude” under the “Vertex modeling” toolbar (pointed by the arrow in the following figure).


I strongly suggest you working on only one eye or the mouth each time, as it is easy to get messed up with both eyes and mouth selected.

Upon clicking “Fast Extrude” you will see a yellow handle. Adjust the yellow handle to push the selected faces (those of your selected eye or mouth) inwards and you will see something like this.


The selected faces are still under select. Adjust how thick you want your pumpkin to be by adjusting the yellow handle. When you are satisfied with the adjustment, press the delete key to delete the selected faces. You will see something like this upon finishing the procedures for both eyes and the mouth (I have toggled to “Select object” mode so you can see the result more easily).


Actually using “Fast Extrude” is mainly to create the illusion of thickness of the pumpkin. Here the pumpkin in fact has no thickness except around the eyes and the mouth. You can actually use “Thickness” under “Surface modeling” toolbar (pointed by the arrow in the next figure). But using “Thickness” will produce a lot of hidden faces that cannot be shown and complicate the model mesh substantially, so in this case this practice is not recommended.

Step 3: Model the stalk of the pumpkin

Change to top view (click “View” in the menu bar, then click “top view”). Press F2 to change to “Select faces” mode.

Select the highlighted and circled faces in the following figure. This is where the stalk of the pumpkin is located.


Change to front view (click “View” in the menu bar, then “front view”). Click “Fast Extrude” from the “Vertex modeling” toolbar. Pull the handle upward to make the stalk.


Adjust until you are happy with the length of the stalk and you will have something like this.


Step 4: Continue to adjust the stalk and export the finished pumpkin to OBJ format

I have scaled up the radius of the ring of vertices at the top of the stalk by clicking the Scale Manipulator and directly typing in the sizes along X- and Z- axes (pointed by arrows in the following figure).


When you are happy with your pumpkin export it to OBJ format for further manipulation. I have exported it to pumpkin_10.obj with the following settings.


Step 5: A few more words

The following is a render of pumpkin_10.obj (with a simple orange material) in Poser 5.


I have included pumpkin_10.obj with this tutorial. Hope you enjoy my tutorial :-)

Happy modeling and Happy Halloween!
