Step 4: Rockets

ROCKETS! Make some rockets for your spaceship using the lathe tool

1. NAME your OBJECTS

  • Use OBJECT | PROPERTIES and name your saucer "Saucer"

  • (Note - on older versions of Anim8or, we used SETTINGS | OBJECT)

  • Name any objects you create in your Flying Saucer file from now on

2. CREATE a NEW OBJECT

  • Use OBJECT | NEW to create a blank screen for your ROCKET

  • (multiple objects can be stored in the same AN8 file - just keep them named appropriately!)

3. From the SIDE view, DRAW a PATH

  • Choose the SIDE view (Key-4)

  • Set the OPTIONS | GRID | SNAP to GRID (Spacing) option to ENABLE

  • Use a CURVED PATH tool and draw as follows

    • Starting left side right on the Z-Axis, click and drag to draw the "nose" of the rocket

    • Continue dragging the little red square to establish the next points; try to draw the rough outline shown here using just six points


This curved path is called a "SPLINE"

4. REFINE the SPLINE

  • Perfect the End Points

    • Click on an end point and you can move it so it lands PRECISELY on the Z-Axis

  • Make some corners

    • Choose a point like the tip of the tail and double click it

    • The "Knot Editor" lets you make it a CORNER rather than smooth point - Click OK

    • Make all the other points corner points EXCEPT the one on the "back" to give your object a more classic rocket like profile

  • Tighten the curve

    • Click on the curved point on the back of the rocket spline, and adjust the green "handles" to shorten the curve. Less curve can reduce the polycount

5. BUILD - LATHE

  • Use BUILD | LATHE and select the Z-Axis

  • Both the START and END should be closed

  • Click OK

    • If it looks like a mess, you probably didn't draw your rocket from the SIDE view. You can adapt by hitting UNDO

    • Try the LATHE command again, this time set the axis for the one that DOESN'T appear in the legend in the lower left of the screen

  • DELETE the SPLINE

    • The thin black line that you used to sculpt your lathe can now be deleted - it serves no purpose at this point

FLIP the NORMALS

    • Lathed objects always start out "inside out" for some reason. You can correct them with these steps

      • Select your rocket object

      • Use EDIT - FLIP NORMALS

HOLLOW POINTS?!

    • Does the very tip of your rocket oddly coloured or transparent? There seems to be a glitch that we can fix:

      • View the rocket from the FRONT view

      • MOVE the rocket to the left or right of the Y axis

      • Use BUILD | MIRROR IMAGE and choose X Axis to create a duplicate of your original translated along the X Axis

      • If the "hollow tip" glitch is fixed, use this duplicate and delete the old glitchy object

6. APPLY MATERIALS

  • Use OBJECT EDIT to paint the entire rocket a uniform colour

  • BE SURE to NAME your materials appropriately, or they can be lost when you add the rocket to the saucer.

  • To colour individual faces of the rocket you can use POINT EDIT mode, but first you'll find you need to flip the normals


HAVING PROBLEMS SELECTING FACES?

If you have problems selecting faces after lathing, your model may have been lathed INSIDE OUT.

  • Choose the WIREFRAME view - can you see the faces being selected now? Are they yellow on the INSIDE?

  • Here's how to "FLIP the NORMALS" to turn your object right-way out.

    • Go back to OBJECT EDIT mode

    • Select the object

    • Use EDIT - FLIP NORMALS

7. COPY to the SAUCER

  • Use "QUAD" view by tapping the DEL key in the lower right corner of your keyboard

  • COPY (CTRL-C) the rocket object, and PASTE it (CTRL-V) into the Saucer Object window

  • MOVE and SCALE the rocket to fit properly

  • Is the rocket facing the wrong way?

    • View the model from the TOP view

    • Use the ROTATE TOOL, but do it using only the RIGHT mousebutton - it rotates it more intuitively on only ONE axis on your screen.

8. POSITION and MIRROR

  • Select the rocket and use BUILD | MIRROR IMAGE (X-Axis Mirror) to create a symmetrical duplicate on the other side of the saucer.

Step 5 - Time to add some tail fins, using the EXTRUDE tool
