Week 15
:

 


 





Goals:
  1. Introduction to particle systems
  2. Ceating explosions
  3. Using MicroDEM to download and edit Digital Elevation Maps
Key Points:
  1. Blowing up stuff using PArray
  2. Creating the chunks
    1. Exploding_asteroid1.max
    2. Create the PArray in the top view
    3. Emitter: sphere, View port display-mesh, Part. type: object fragments
    4. Object fragment controls: Thickness-5, Chucks-150
    5. Timing: Start-10, Life-90
    6. Materials - Get from emitter
    7. Rotation and Collision:10
  3. Visibility
    1. Visibility track
    2. Key 0, Vis 1, step out - Key 10, Vis O, step in
  4. Explosion Material
    1. Plane in to top view and align to camera
    2. Hercules map to diffuse channel, HerculesM to Opacity
    3. Time:10, End: hold
    4. Make copy of plane and place behind
    5. turn off cast and receive shadows, no gloss, no shine
  5. Omni light, mult: 4, R: 255, G: 111, B:56
  6. Glow
    1. Render/Effects/Lens Effects/Glow, pick the omni light as source
    2. Highlight Glow, Occlusion 0, Glow behind off, Glow size: 300
    3. Options Tab: Apply to light only
    4. Right radial color to: R:242, G:150, B:0. Render frame 50
    5. Animate the glow intensity
      1. Frame 0, 0, step out
      2. Frame 11, 0, step in, linear out
      3. Frame 12, 50, linear in and out
      4. Frame 30, 0, linear in
  7. Blur
    1. PArray properties -blur object, render window to 2 frames
    2. Render/Effects/Blur, Radial, Pixel radius 10
