In this tutorial I will explain on how to make a tank track
and then how to animate it, its very easy, in 5 easy steps your done,
it will cost you 10 min!. I also learnt this over some tutorials but I
can't find them on the internet any more. So I though to write one, this
is also my first tutorial I ever wrote. And don't watch my English it's
rather BAD. Now lets start.
1. Making the Track Segment
Ok, first we need to make the segment of the track. We will make a basic
track segment of a tiger tank.
Allright lets start. Go to the top view and make a box with
the parameters like the picture below.
Now right click the object and covert it editable poly.
Now go to poly selection and select the polygons shown in the picture
Now press the little button next to the extrude button,
and then you enter 15 and hit "Ok".
Now select the opposite polygons on other side of the object (see picture
below) and extrude them also with 15.
Ok, now go to vertex selection mode and move
the vertex until you got something like the picture below.
Now right click the text "top view" and select
the bottom view. After that select these polygons and bevel them as shown
in the picture.
Next thing to do is to make a new box with the parameter like this picture.
You should also convert it to the editable poly.
Now go to polygon selection and select the top polygon and
extrude him with 8.
Now go into vertex mode and to the front view, now select
the top left vertex and move them to the right until they looks like the
picture, now do the same with the right top vertex.
Now deselect the vertex selection and press the attach button
and select the first object we made (make sure that your object are in
place like the picture below)
Now your 2 objects becomes 1, this is were we stop to model the segment
for the tutorial.
2. Path for your track
Now we must make a path that our track is going to follow.
Now make a Line (Shapes-->Line shape) now draw a nice path on how the
track must go and then close the spline.
Spline that marks the route of the track.
3. Duplicate the track segment
Now its time to duplicate our track segment so that it will be a track.
Select the track segment and select the move option
now hold down shift and drag the track segment so that the segment fits
in the duplicated segment, now you can enter how much copies of the object
you want enter a number that fills your path.
I have used 80 copies.
Now we have a rolled out track now select one segment (the
last or the first segment) and hit the "attach list" button,
now select all the track segment and hit the attach button.
Now we have 1 object that is the hole track.
4. Letting the track follow a path.
Now its time to let the track follow the spline, to do this select the
track object and go to the modifiers selection and select PathDeform.
Now hit the Pick Path button and select the spline we made.
Now if your track looks weird then check the Path Deform Axis z, x, or
y to make it right, if your track is flipped in side out then check "flip".
Mostly the track is to small, to make him bigger scale the spline NOT
THE OBJECT if your track is in place then you will notice (if you entered
to much copies of the track segment) that the track goes in him self (overlapping)
or that there are not enough track segments , if this is the case then
you select the track object and go to element selection of the editable
object, now you see your track not following the path anymore, now select
the track segment that were to much and delete them or when you want to
add some segments then you must select a track segment and shift drag
him to copy it. Now unselect the element selection and select PathDeform
(NOT A NEW PATHDEFORM) Now your track follows the path again, look if
the track is good, if not delete more segment until the track is good.
Track is overlapping.
5. Animating the Track.
This is very easy to do just go in auto key mode scroll to frame 100 and
select the PathDeform modifier of the track object and enter a number
(like 10) in the percent box and press play, now your see your track move
along the path.
Here is animated example with wheels :)
