Modeling a High Poly World War II Willys Jeep in Modo - Part 5

Today we're bringing you part 4 in the Willys Jeep tutorial series where you've been learning how to model a high poly World War II era vehicle using Modo 601. In this lesson you'll continue refining the frame and bumper sections, and then begin adding some of the smaller detail pieces. Including the reflectors, lug nuts and rivets. Michael will also get you started on the interior block-out.

Project Overview:

This tutorial series will teach you how to model a Willys Jeep from WWII in Modo 601. The tutorial is created for users new to modelling in Modo. It requires a basic knowledge in Viewport navigation and UI. We’ll first go through the planning stage, and then we’ll setup the blueprints and plan how we should separate the parts of the model.This tutorial will have five parts, and at the end of the fourth part. We’ll have our Willys jeep modeled with the interior blocked out. In the fifth and final part we’ll proceed to detail the interior.

Step 1

Lets start this part of the tutorial by adding a edge loop to our frame. Use the 'Slice' tool to cut both segments at once, as shown.

Step 2

Select all the vertices above our new edge and move them down a bit. Use the reference to put it in the right place.

Step 3

Select the polygons making up the front bumper and Cut/Paste them. It will separate the geometry.

Step 4

Scale it a bit in a vertical axis. Also select the polygons highlighted in the image and Delete those.

Step 5

We will add thickness to the bumper. Like in the previous parts you can use the 'Thicken' tool or copy and paste the geometry, Flip the polygons, using the 'Push' tool move it away and finally Bridge edges. Unfortunately the 'Thicken' tool once again gave me additional geometry so I went with the second option. How you approach it is your choice. I personally prefer more work but no fixing of the geometry after.

Step 6

After duplicating the geometry and pushing it remember to Flip it with 'F' key. The Double-click the open edges and use the 'Bridge' tool.

Step 7

The duplicated geometry looks wonky after using the 'Push' tool. So use the 'Scale' tool to fix it.

Step 8

Add support edges as shown in the image below.

Step 9

Select the open edges we created by detaching the bumper geometry and Move them forward. You can cap those but it won't be visible, no need to add geometry by doing so.

Step 10

Lets refine the shape of the back bumper. Using symmetry and the 'Move' tool, fix the bumper's shape.

Step 11

With symmetry activated Create a Cube. Symmetry will also create it on the other side which in this case is what we want. No need to create a new mesh object for these elements. I created them in the frame object.

Step 11 Image

Step 12

Change views to the Side, and Align our box to the blueprint.

Step 12 Image

Step 13

Bevel the corner edges to match the boxes to the elements you can see in the reference. I used a value of 1 for the 'Round Level'.

Step 13 Image

Step 14

Move the vertices to further match the shape.

Step 14 Image

Step 15

Duplicate the geometry. This time we won't use the 'Push' tool since we want it to scale only in one plane. Select the inner geometry, and Flip it. Activate the 'Scale' tool and Scale it in the Red/Blue plane.

Step 15 Image

Step 16

Double click the open edges and Bridge them.

Step 16 Image

Step 17

Add support loops. You can add all of them with the 'Loop Slice' tool with Symmetry and 2 segments.

Step 17 Image

Step 18

Once again add support edges. This time add them to the main frame geometry. First add edges running along the shapes with the 'Loop Slice', as shown.

Step 18 Image

Step 19

You also need to add support edges across the shape. Use 'Add Loop' to create edges like in the image below.

Step 19 Image

Step 20

Toggle subdivision to check if everything smoothes Ok. Remember you can use the 'Reflection' shading mode to check the curvature.

Step 20 Image

Step 21

Select the body mesh object or create new one. Create a Cylinder in the Side view aligning it to the back light reflector part.

Step 21 Image

Step 22

Move the cylinder to the body surface, and Delete the back polygon occluded by the body geometry.

Step 22 Image

Step 23

Using the 'Bevel' tool inset the center polygon twice.

Step 23 Image

Step 24

Using the 'Bevel' tool again, Extrude the loop of polygons to create the extrusion around the reflector.

Step 24 Image

Step 25

Using 'Loop Slice' add symmetrical support edges. Also Inset the polygon in the center. As you can see, even the 'Bevel' tool can be used to add support loops.

Step 25 Image

Step 26

Next add 2 spheres and align them as shown in the image. Remember that when you create a Sphere by default it has subdivision turned On, so select the sphere polygons and toggle subdivision Off. Also Delete half of each sphere which are being occluded by the reflector.

Step 26 Image

Step 27

Duplicate the reflector. Rotate it with the 'Rotate' tool (by holding 'Ctrl' you can rotate in 15 degree steps) and place it at the back of the body.

Step 27 Image

Step 28

Once again Create new mesh object or create it within the body object. Using a 'Tube' Create a shape like the one in the image below. We will use it to create handle. Don't bother creating it perfectly symmetrical, we will mirror it later.

Step 28 Image

Step 29

Select the center loop around the handle and using 'Loop Slice' add a loop in the middle.

Step 29 Image

Step 30

Delete one half of the handle. Select the cap of the other half and Extrude it a bit.

Step 30 Image

Step 31

In the Top view move the cap up like in the image. You can use the blueprint for this.

Step 31 Image

Step 32

Make the shape more rectangular by selecting the polygons and scaling them. Do this for the polygons shown in the image. Do this symmetrically for the bottom, and also do this for the cap.

Step 32 Image

Step 33

Cut the cap like in the image below. You can use the 'Edge Slice' tool to cut it easily.

Step 33 Image

Step 34

Lets start adding support edges by adding an edge in the place where cylindrical part goes into more rectangular one.

Step 34 Image

Step 35

Scale the polygons as shown in the image to make the part used for attaching the handle to the body bigger.

Step 35 Image

Step 36

Add loops like in the image, and move the center left vertices to give a bit of a curvature to the side of the handle.

Step 36 Image

Step 37

Just like many times before, using the 'Mirror' tool and snapping, duplicate the handle geometry.

Step 37 Image

Step 38

After aligning the handle to the blueprint I check how they look. Unfortunately after comparing it to the reference I wasn't happy with the result. I Scaled the handle up and moved it. No point in keeping close to the blueprint, if the final result doesn't look good or doesn't match the reference you use. I also checked if a subdivided handle looks ok.

Step 38 Image

Step 39

To create the handle on the corners, duplicate the handle and move it closer to the corner.

Step 39 Image

Step 40

Select the vertices like in the image and move them closer to the body. You want the corner of your geometry to slightly touch your body mesh.

Step 40 Image

Step 41

Be sure in your 'Action Center' menu, none of the action centers are selected. Activate the 'Rotate' tool and click the Right mouse button in the place where both meshes to touch. We will now rotate the selected vertices around this point.

Step 41 Image

Step 42

If you didn't use symmetry, use the 'Mirror' tool to duplicate the handles on the other side. Snap the mirror to the center edge of the hood.

Step 42 Image

Step 43

Lets now refine the interior a bit. Be sure your edge below dashboard is straight. I used snapping with the 'Move' tool to snap the edge to the side vertex. You can also use the Scaling tool to straighten the edge.

Step 43 Image

Step 44

Select the polygons like in the image. We will add support edges to these. It will be easier to do once we isolate our selection.

Step 44 Image

Step 45

Use 'Shift+H' to isolate the selection. Then using the 'Bevel' tool inset those polygons a bit. It will create new edges around our polygons. By doing so we also change the edge flow.

Step 45 Image

Step 46

Extrude the polygons below the dashboard. Also use the 'Scale' tool to flatten it.

Step 46 Image

Step 47

We will need to once again change the edge flow. So Select the polygons as shown in the image.

Step 47 Image

Step 48

Isolate the selection and Deselect the polygons on both sides.

Step 48 Image

Step 49

Add a loop with the 'Slice' tool. We don't want any new edges on the side polygons and that's why we deselected those.

Step 49 Image

Step 50

We still need to connect this new edge to the side polygons. Add an edge like in the image with the 'Edge Slice' tool.

Step 50 Image

Step 51

Unhide the rest of the geometry and select the polygons as shown in the image. Once again we will isolate it to create a better edge flow.

Step 51 Image

Step 52

Like in the previous example, Deselect the polygons like I did.

Step 52 Image

Step 53

Using the 'Slice' tool, add an edge. Remember to constrain the slice plane with the 'Ctrl' button.

Step 53 Image

Step 54

Once again we need to cut the polygons. Using 'Edge Slice' add one edge. Right now we have two triangles creating one four sided polygon. We can easily remove the edge dividing it into two triangles with the 'Backspace' button.

Step 54 Image

Step 55

Once again check if your plane is flat. Also move it as far back as it should be. Since this plane should be angled, be sure you align its depth to the depth of the top edge of this plane.

Step 55 Image

Step 56

Choose 'Linear' falloff. Activate the 'Move' tool, and by using 'Auto size' and choosing the right axis, align the falloff like in the image. You can now move those polygons in the side view to get something like in the image.

Step 56 Image

Step 57

With 'Add Loop', add support loops. In the 'Add Loop' properties, check 'Absolute distance' before adding the edges. Test the advantage it gives in a situation like this.

Step 57 Image

Step 58

Select the polygon in front of the benches. Using 'Add Loop' again, add a support edge only for the selected polygons. It will create n-gons, but once again they won't mess anything up.

Step 58 Image

Step 59

Do the same thing to the sides of the benches. Since our polygon loops ends with n-gons, we will need to cut those with 'Edge Slice'.

Step 59 Image

Step 60

Below you can see how I finished the edge flow.

Step 60 Image

Step 61

Also add support loops between the benches. You can use 'Loop Slice' with symmetry and 2 segments and 'Slice Selected' checked. Before using 'Loop Slice', select the polygons you want to cut.

Step 61 Image

Step 62

Create a separate 'Mesh' object for interior. Create simple boxes to blockout the seats and steering wheel. I won't go into detailing the interior in this part. Blocking it out now though helps with judging the proportions.

Step 62 Image

Step 63

Create a new 'Mesh' object for the rivets. In the side view create a Cylinder and Scale it to the rivet in the blueprint. Since there is no need to subdivide the rivets, be sure to use more segments for the cylinder. I used 48 sides.

Step 63 Image

Step 64

Using the 'Bevel' tool, recreate the shape shown in the image.

Step 64 Image

Step 65

Using subdivision on the rivets would needlessly ramp up our polygon count. Since they are a really small elements, we can bevel the edges and just use material smoothing. Bevel the edges with 1 as the 'Round Level' value. Also Inset the center polygon to get a support edge in the middle. This support edge will make the smoothing look better (since we won't subdivide this element it won't help to retain the shape).

Step 65 Image

Step 66

We will use the 'Paste Tool' to copy the rivets onto the body geometry. Activate the 'Background' constrain in the snapping menu ('F11'). Select the rivet polygons and copy them with 'Ctrl+C'. The 'Paste Tool' will paste whatever geometry you copied. With the background constraint, you can click on the body geometry to create new rivets.

Step 66 Image

Step 67

Using reference, duplicate the rivets onto the body geometry. Be sure you don't drag the scale gizmo on the newly created rivet. You can also set the 'Bias' in the 'Paste Tool' properties. It will offset your mesh from the geometry you are copying onto.

Step 67 Image

Step 68

Unfortunately the 'Paste Tool' doesn't rotate the rivets based on the underlying polygons normals. You will have to manually Rotate them after placing them on the body geometry.

Step 68 Image

Step 69

Lets now create the nut. Create a separate 'Mesh' object for the nut and create a 6 sided Cylinder. Be sure to make it slightly bigger than the rivet. Look at your reference to nail the scale.

Step 69 Image

Step 70

Select all of the edges and Bevel them just like the rivet. As you can see after beveling we get this shading gradient on the front and side faces.

Step 70 Image

Step 71

To fix the shading issue, Inset the center polygon and add 2 loops around the nut.

Step 71 Image

Step 72

You can once again use the 'Paste Tool' to place the nuts on the wheel. Some times the 'Paste Tool' creates copies something you didn't want. To check if everything is OK, isolate the nut object and look around. Also Rotate the nuts so they are oriented differently.

Step 72 Image

Step 73

Add more nuts to the inner detail of the wheel. You will need to Scale those to match. Also add them to the handles.

Step 73 Image

Step 74

In the previous image you can see that our mudguard is a bit too low poly after subdividing. To change that, select the body object and in the right bottom corner, in the 'Properties' tab. Find the 'Subdivision Level', you can increase it to 3.

Step 74 Image

Step 75

To make our model a bit more interesting, add a box under the body. In the reference you can find some type of tank under the body. You can use details like this one to break the symmetry of your model.

Step 75 Image

Step 76

Remember to add support loops to the tank. Inset the caps and add support loops around the shape.

Step 76 Image

Step 77

Check if all the elements looks good after subdividing. In the next part we will jump into detailing our interior. You can also check your reference to see where you can reuse your rivets and nuts, to add more details without creating new objects.

Step 77 Image
