Burning Laser Effect in Maya from Gabriel Gumucio on Vimeo.
This tutorial assumes that you have an intermediate knowledge of Maya.
Import the geometry
Download the scene here:
www.gabrielg.se > Tutorials > Effects tutorial "Burning laser"
Load up the scene file, which includes the following geometry:- Plate
- LaserCannon and LaserBeam
- Motion Path curve (MotionPath)
- Glowing Sphere (LaserImpactGlow)
Set up animation
- Create a Locator
- Rename it MotionPathLocator
- Select MotionPathLocator and MotionPath and go to Animate>Attach to Motion Path> (Options)
- In the Options, choose Start/End, and enter ”50” as Start Time and ”290” as End Time
Now, let's make the laser beam follow the locator.
- Select MotionPathLocator and LaserCannon (in that order)
- Go to Constrain>Aim> (Options)
- Enter the following values: Aim vector: 0, 1, 0 Up vector: 1, 0, 0
You should now see the laser beam follow the Locator. But it moves linearly, lacking elegance. Let's make the motion a little more interesting.
- Select MotionPathLocator and find the U Value attribute in the Channel Box.
- Scrub to all the frames where the Locator makes an abrupt turn and set a keyframe on U Value at each such frame.
- Select all the keys by click-dragging in the Time Slider, right click and choose Tangents>Flat
Key Shader values
Let's animate the laser beam's shader, to make it turn on and off.- In the Hypershade, select LaserBeamShader
- Go to frame 40 (10 frames before the beam starts to move) and change the Incandescence color to Black.
- Right click and choose Set Key
- Go to frame 50 (where the beam starts to move) and change the Incandescence color to Red (or the color of your choice) with Value (V): 2
- Right click and choose Set Key
- Repeat this operation, but reversed, at the last key frame of your motion path.
