Making Asteroids in 3ds Max with AfterBurn
1. Particle Flow Setup
Open 3ds Max. Go to Particle Systems and create a PF Source icon in the perspective viewport by clicking and dragging.
With the Rotate tool selected (E), rotate the PF Source icon vertically 90 degrees, or enter a value of 90 degrees in the Y axis field.
With the PF Source icon selected, click on the Modify panel button to open its parameters. Here set the values for Length and Width to 0, and change the Viewport % value to 100.
on the Particle View button (or press 6 on the keyboard) to open the Particle View window.
Click on the Birth operator and change the Emit Start and Emit Stop values to -100 and 100 respectively. Set the Amount value to 500.
to the Speed operator and change it's Divergence value to 6.0. This will make the particles spread out a bit.
2. After Burn Setup
Now it’s time to use the After Burn system. Press 8 on the keyboard to open the Environment and Effects window. Inside the Atmosphere panel, click on the Add button. This opens the Add Atmospheric Effect sub-window. Here select After Burn and then click on OK.
You can see AfterBurn
and the FusionWorks Renderer have been added
into the list.
Now create a standard Target Spot light and position it in the scene (Create > Lights > Standard LIghts > Target Spotlight).
Step 4Turn on the Shadow option and choose AB Shadow Map from the drop-down menu.
Now click on After Burn in the Environment and Effects window to open the AfterBurn Manager.
First click on the Pick Particles/ Daemons icon and then select the PF Source icon in the viewport. This adds the PF Source into the list. Then turn on the Show in Viewport icon to see the shape of the actual AfterBurn particles in the viewport.
Now click on the Pick Lights icon and then press the H key to open the Pick Object window. Here select the spot light (Spot001) and then click on the Pick button. You will then see the spotlight added to the Source Lights list.
Go to the Particle Shape parameters and change the Sphere Radius value to 10.0, and set the Var % (variation percentage) value to 10.0. Then click on the AFC icon and set the Hi Value to 40.0.
In the Colors rollout, click on the Color 1 icon and change the color values from light grey to dark grey going from left to right.
Click on the Ambient Color box and choose Key Mode.
Go to the Rendering
parameters and turn on the Self Shadows, Shadow Cast and Shadow Receive options.
Now render the scene and see how it looks. It looks impressive, but we need to add some more detail.
Go to Helpers > After Burn Daemons > Explode and draw an explode icon in the viewport.
Click on the Pick Particles/ Daemons icon and pick the Explode daemon.
Change the Color of the Explode to match what's shown in the following image.
Render the scene to see the difference the Explode daemon has made.
Increase the Multiplier value and render again to see how it looks.
