How to Make a Sci-fi Film, the Easy Way

I will start with this first although it does not need to be done in this order, you can construct models in goolge sketchup or other software, these can be moved around in your scene in wax but their parts cannot move. If i had a model of a fighter landing and the landing gear extending i would have to make one model for the fighter and one for each element of the landing gear, although in sketchup this can be one model with a few groups or components to use it in wax the gear and fighter must be separate models otherwise they will be unable to move relative to each other. sketchup models can be found at the google 3d warehouse http://sketchup.google.com/3dwarehouse/cldetails?mid=7e7ef910316459a3b281964dca26f211&prevstart=0 this is a good scifi collection.
or across the internet searching for what you want followed by the word "mesh"  example: starship mesh  , space fighter mesh  .these meshes will be of a variety of formats but wax 2.0 can only take those in "3DS, Quake MD2 & MilkShape MS3d" . so when you have a model you like you must convert it.
IMPORTANT: when making a film/animation one of the first things people will see is your models, a bad or boring mesh/model will ruin a video.

Now we must convert the models to .3ds  .

In wax we will want to animate our models infront of a background, this could be a still image or a video. IF it is a video AVOID camera shake as this will look awful unless you can make the 3d model wobble in exactly the same way to compensate for it(very very hard). in my film here i used this image as a still, it was a screenshot from sketchup .

The next stage is opening the models in wax 2.0, this is how. choose the add media files icon above thew mediapool in wax. select a picture file .jpg/.bmp/.png in the pop up box, what picture this is does not matter as it will not be visible in the final video. Drag and drop this still into the timeline at the top track, stretch it until it lasts as long as you want
Then switch from media pool to video plugins. select the model loader plugin and drag and drop this onto the image track, click on the model loader plugin which appears and select the 3ds file you created earlier. wax will then prompt you to find all the textures, this is easy and almost automatic( just keep clicking ok) if they are in the same folder as the model. when all textures are found the model will appear in the viewer /preview screen.
After this bring in your background clip in the mediapool  and drop it into a track below your model loaded track. the image/video will appear in the background in the preview area.

Now we have the model but as time passes in the video it just stays still, HOW BORING! we can make it move though.
open up the transform 3d plugin that automatically drops in with the model loader and notice that there are a range of fields describing the position, rotation and size of the model. all are currently set to default. to make the object move set the position you want at the start of the motion by typing in the data,  then click the little clock icon on all the quantities you want to change during the motion. then move the time slider along to the time at which you want the motion to stop, type the new values for position, rotation and scale into the transform 3d list and click the clock icon for each one again. then play the video and watch as the object moves between the positions/rotations/scales as time passes. AWESOME! also note that the positon of the camera in 3d space can be set and keyframed using the camera section under global settings, this will move the camera relative to the models but picture/video backgrounds will remain unchanged.
If you add more tracks then remember that the ones at the top obscure the ones below them.

once you are satisfied with how your video runs in the preview( audio might not work correctly at this point) click the project settings button at the top and set the details( see image) then click the button to the right of this to render ( can take up to 10 minutes to render). there are many problems that can occur, PM me with an exact description of what you did, what went wrong and what wax said and i will try to tell you how to correct this( it is a while since i used wax i have moved on to other programs now but wax is the easiest to learn). 

When each scene of your film is created in wax use software such as windows movie maker to put them in order and add titles between them before saving as your film.

So, you say, i want to put myself into a computer generated scene/ have the model behind me in the video. there is a way to do this first film yourself against a green background(blue can work as well), import this video into wax and place it  your video as the top track. then drop a green image( just plain green) into the track below. use the chroma key plugin to cut out the green in the video of you and let the green of the image in the track below replace it. render the video. repeat this until all the background has been replaced with pure green by removing one shade of the real( in your original video) background at a time and then placing the render as the top track in a new wax project and cutting out the next shade until all the background has been replaced with the green image. finally import the render containing the perfect green background into wax and use chroma key to cut out this background , place the video you want to superimpose yourself onto in the track below.

wax also contains the particles plugin which can be used for smoke or explosions, simply drag an image into the tracks and stretch it to start at the point you want then drop in the particles plugin. this is set to a fire effect but by changing the particles settings it can be used in many other ways. the following set ups will produce:
