Model a Rocket with particle trail

In this tutorial, I'm going to show you how to create a rocket using NURBS, and then animate its movement using path curve. I'll also show how to make a simple smoke trail.

[Click Here to View Large Image]

First go to create/CV curve tool.

[Click Here to View Large Image]

Then just click to make points. Create a simple profile for the rocket. If you make a mistake, just press delete and the point will be deleted. When you've finished, press Enter.

[Click Here to View Large Image]

So you will get something like this:

[Click Here to View Large Image]

Next, select that curve and go to Surface/revolve option box

[Click Here to View Large Image]

In the options window, set it to rotate around the Z axis.

So now, you've got some basic rocket geometry.

[Click Here to View Large Image]

If you want to tweak the rocket shape, just select the curve and edit it. The rocket shape will be updated. Note that construction history must be on (it is on by default).

[Click Here to View Large Image]

Now select the rocket geometry and go to isoparm mode and select the last isopram.

[Click Here to View Large Image]

Then go to surfaces/planar. This will create a planar surface from the selected shape.

[Click Here to View Large Image]

Now create more curves like this.

[Click Here to View Large Image]

Select them all.

Now, revolve them.

From the top view, create another curve. This will form the shape of the wing.

Duplicate it.

Move its points to the axis. Just select all CV's and hold X and move them towards the axis.

Tweak it.

Now select both curves.

And go to surfaces/loft. This will make a surface between the selected curves.

Now we have the wing, but it is one sided. Since its pivot point lies at 0,0,0 - just duplicate it and set the negative scale around the Axis (I think it was Z in my case).

[Click Here to View Large Image]

Now select both wing surfaces and group them.

[Click Here to View Large Image]

Then go to duplicate options (now it's called duplicate special) and make three copies at every 90 degrees around the Z axis.

So the rocket geometry is completed.

Now select all curves and delete them. You can mask selection by unchecking surfaces. Then just grab the selection and only curves will be selected. Also delete history on surfaces.

[Click Here to View Large Image]

Assign shaders to the rocket.

Create point light. Move it to the back of the rocket and set intensity to something high (5 or 10) and set decay to linear.

Press 7 to see the lighting in viewport.

[Click Here to View Large Image]

Select rocket geometry and light and group them. Set the group's name to rocket.

[Click Here to View Large Image]

You can freeze transform the group. This will set all attributes to 0. You can make a layer and put the rocket in it. Refer the help for more info about layers.

[Click Here to View Large Image]

Now for a simple terrain. Create a polygon plane and set divisions to 100x100. Then go to sculpt geometry tool

[Click Here to View Large Image]

Deform the surface to look like a terrain.

[Click Here to View Large Image]

Make directional light and set intensity to 1.2 and color to light yellow or orange.

Make path curve for rocket.

[Click Here to View Large Image]

Now select rocket group and the path. Go to animation mode motion paths/attach to motion path option box.

Set time as you wish, I've set mine to 100 frames. As you can see, the rocket tip is oriented to negative Z. Set front vector to Z and up to Y. Check inverse front, so it will inverse Z to negative Z.

[Click Here to View Large Image]

When you attach it, the rocket will be set to the beginning of motion path. Play the animation. Cool?

Now smoke. Go to dynamics mode and go to particles/create emitter. By default it will create an omni emitter at 0,0,0. Also it will create a particle1 node. Move the emitter to the rocket's back:

[Click Here to View Large Image]

Then MMB drag the emitter to rocket group in outliner. This will parent the emitter to the rocket, so its movement is relative to the rocket.

[Click Here to View Large Image]

If you play the animation, the particles will appear behind the rocket. Select emitter and set speed to 0.2.

[Click Here to View Large Image]

Under particleShape1 go to render attributes and set Particle Render Type to Cloud (S/W). Set radius to 0.4 (these numbers are relative to scene size, so you might need to experiment).

[Click Here to View Large Image]

Then white particles are assigned the particle cloud shader to them (same thing as assigning shader to geometry). Note: make sure that the mouse is over particle.
Make color dark gray.

[Click Here to View Large Image]

Then click on the checker on the right side of Life Incandescence attribute. This will open create texture window. Create ramp texture.
Life Incandescence will take the values from ramp, and calculate particle color based on the life of each particle. In hypershade you can see three new nodes.
Edit the ramp.

Note, the bottom of the ramp is beginning of particle's life and the top of the ramp is end. Tweak the colors to start with bright orange and change to orange and than to black.

Also make one ramp for life transparency. Set its color to go from gray to white.

This will make particles fade.

[Click Here to View Large Image]

Now you can see that every particle is the same size. I don't like that. The trail shall get thicker at the end.

So go to per particle attributes tab and click general button. Then select RadiusPP attribute, and click add.

[Click Here to View Large Image]

Notice that RadiusPP is now in the list. Hold RMB on it. You shall get small popup menu. Choose create ramp. Particle size will be connected to the ramp texture.

[Click Here to View Large Image]

Hold RMB on RadiusPP and choose edit ramp. Edit the ramp so the first color is gray with .3 value and the last color (top color) shall be set to white (value of 1).
This means that every particle will grow from .3 to 1.

Now you can render. I don't like that gaps in the trail.

[Click Here to View Large Image]

Select emitter and change rate to 400. Now more particles will be emitted.

Also you can see that particles die too fast (trail is too short). Under particleShape1 there's a tab called lifespan Attributes. Open it and set Lifespan Mode to Random Range and set lifespan to 2, and Lifespan Random to 0.2

This means that every particle will live 2 seconds (48 frames) plus/minus 0.2 seconds.

[Click Here to View Large Image]

Now the trail could behave more randomly. To do that select the particle and go to ;fields/turbulence. Set attenuation to 0. and magnitude to 2.5 or 3. Magnitude is the strength of the field. Also set frequency to 3 or 4.

[Click Here to View Large Image]

Now make a NURBS sphere and scale it. This will be the sky.

Assign surface shader to it and assign ramp texture to its color. Set the colors like I have. Also set ramp to U ramp. Also if you look at the Sphere Shape node, go to render stats tab and turn off cast shadows and receive shadows.

Now set renderer to mental ray. I prefer using mental ray with particles and fluids since it gived nice results especially when using final gather. Also mental ray provides faster raytracing with volumetric objects.

Select Directional light that you previously created and turn on raytrace shadows. Increase Shadow Rays to 5. Under mental ray settings turn on final gathering. Final gather will use that sky sphere as an illumination object.

[Click Here to View Large Image]

Now if you render, you will see some nice results. However I don't like the shading of the particles. It looks good from a distance but it's useless for close ups.

[Click Here to View Large Image]

Go back to life incandescence ramp. It should look like this. Note that the ramp is using only flat colors. But what if we could map texture to each of these colors?

Of course we can do that. Remember -- in Maya, you can map texture to everything.

[Click Here to View Large Image]

So create solidFractal and Stucco textures. Refer to Lava shader tutorial to see how to make it look like fire. Map the solid fractal to first color of the ramp (just MMB drag texture to color in the ramp). For the second color, use stucco with shaker set to 30 or 40 and map one color with fractal used in the first color. Third color of the ramp should be black. Also, it's a good idea to map color attribute of particle shader to fractal texture with small color gain. I do this just to get slight color variation.

[Click Here to View Large Image]

So from now it's all tweaking. So tweak!

[Anonymous] ( 2009-03-24 04:20:02 ) [Post Comments]

frankly, to those complaining that the tutorial wasnt good for newbies if your that new to maya you should probably learn the fundamentals before particles. Excellent tutorial! I agree there was a hitch with the smoke part of the tut, but overall very good.

where the smoke tab came from? Any help would be nice.

this is awesome cheers for doing it! but some of the shader stuff just got me confused, it would be sooooo good if you did like a very slow pictre by picture one spreading out that section for the simple ones like me!

[Anonymous]TS ( 2009-01-18 03:02:56 ) [Post Comments]

Hey man your tutorial doesn't work... Where does that "Smoke" tab come from? You set the particle type to Cloud, and then you proceed on talking about the "Smoke" tab which does not exist. How did you get that "Smoke" tab?

Thanx a lot dude. Very good tutorial. I only had problems with rendering. The smoke did not render properly after I followed your steps but that might be because im using the PLE version of Maya....:(
