NewTek Lightwave 3D: Modifying Lightwave Objects

  1. 1. Animation V Modifying Lightwave Objects
  2. 2. Object Properties  Properties dialogue box  Some neat tricks you can do to your object  Morph your object into another object  Change the way the object appears  Shortcut = p
  3. 3. Let’s Get Started  Start up Lightwave 3D  Select Load Object (+)  In the Landscape folder, select Ground.lwo
  4. 4. Loading Objects  Whoa, what happened?  When loading large objects, Lightwave changes the grid size to fit the object on the grid  The camera moves back so it can shoot the large item
  5. 5. Scaling Things Back to Size  Select the Camera  Check the settings on the numerics  Grid size jumped to 500 meters!  Camera is back from center nearly 5 kilometers from center
  6. 6. Scaling Things Back to Size  Select the View tab  In the Grid section, select Grid Size  Type in 2 and press OK  Now the ground really covers the whole space
  7. 7. Bring the Camera Back  Select the Camera  In the numerics box change the settings:  X = 0 m  Y = 1.75 m  Z = - 8 m  This is raise the camera and back it up a little from center
  8. 8. Let’s Look at Something  From the Items tab, select Load Object  From the Animals tab, select Triceratops  Change your view to the Camera view (6)  Press F9 to see what you have so far
  9. 9. Clean Up the Lighting  Select the Light  Switch to the Top view (2)  Using the Modify tab, move the rotate the light so it’s lighting the dino better  Do another test render to see how he looks
  10. 10. How About Some Background?  Lighting is better, but he needs a backdrop  Select Windows > Backdrop Options
  11. 11. How About Some Background?  Lighting is better, but he needs a backdrop  Select Windows > Backdrop Options  Turn on the gradient backdrop  Do another test render
  12. 12. Modifying Object Properties  Under Objects, make sure Triceratops is selected  Click on the Properties button (p)
  13. 13. Modifying Object Properties  Select the 2nd tab Deform  Morphing  Displacement map  Enable Bump
  14. 14. Modifying Object Properties  Morphing  Change your object into another object  Displacement map  Warps your object based on an image or texture map  Enable Bump  Roughs up the surface of your object
  15. 15. Add a Displacement Map  Click on the T button under Displacement Map  T stands for Texture  Under Layer Type, select Image Map
  16. 16.  Since our dino is mostly a cylinder, under Projection choose Cylinder  Under Image, choose Load Image Add a Displacement Map
  17. 17.  In the Reflections folder, select FractalReflections.tga  Change the Texture Amplitude to 0.5 Add a Displacement Map
  18. 18.  Do another test render to check him out  This displacement is caused by an image and doesn’t change over time  Modify the displacement by choosing different Texture Axis Add a Displacement Map
  19. 19.  Render this frame (F9) and Save the frame as Displacement.jpg to the desktop. Take a Picture for your Homework
  20. 20. Animated Displacement  Change the Layer Type to Procedural Texture  Change the Procedural Type to Ripples  Press the Play button to see how this displacement map changes over time
  21. 21. Animated Displacement  Change the settings:  Texture Value = 0.05  Wave Sources = 1  Wavelength = 0.5  Wave Speed = 0.02  As you change these settings, watch what happens to dino!
  22. 22. Decisions, Decisions  Once you have your settings the way you like or don’t like, it’s time to choose  Use Texture  Remove Texture
  23. 23. Reset the Board  At the bottom of the Displacement Map dialogue box choose Remove Texture  This turns it off for now, but you can go back and turn it back on if you like  We are going to try out some other tricks for now
  24. 24. Render Tab  Changes how the object is seen on camera  Or not seen if you like  Options  Change to a solid color  Make it semitransparent or invisible  Make parts of the object invisible  Whether it casts a shadow or can have a shadow cast on it
  25. 25. Clip Map  Makes parts of the object invisible based on an image or texture
  26. 26. Make a Clip Map  In the Render tab, select the T button for Clip Map  Under Layer Type, choose Image Map  Under Projection, choose Cylindrical  Under Image, choose FractalReflections.tga
  27. 27. Make a Clip Map  This effect you can’t see until you render  Press F9 to check it out
  28. 28. Take a Picture for your Homework  Save a JPG of this render to the desktop and call it ClipMap.jpg
  29. 29. Make a Clip Map  Change the Texture Axis to Y and X and render those versions!  Like the displacement map image, these will not change over time
  30. 30. Make a Clip Map  If you want them to change over time, use an animated texture like ripples
  31. 31. Render Tab  Matte Object  Turns your object into a solid matte color  No shading or highlights to the object  One flat color  Interesting effect with a clip matte
  32. 32. Make a Matte  Turn off the Clip Map texture if needed.  In the Render tab select Matte Object  Click on the black square and select a color  Render the frame and check it out
  33. 33. Render Tab  Object Dissolve  Turns the whole object to whatever opacity setting you would like  Opaque  Semitransparent  Invisible  Distance Dissolve  Makes the object become completely invisible as it moves away from the camera  Kind of like in a fog
  34. 34. Make a Ghost  Turn off the Matte Object  In the Object Dissolve window, drag the arrows until you have a setting @ 50%  Render the frame and check it out
  35. 35. Take a Picture for your Homework  Save a JPG of your render to the desktop and save it as Dissolve.jpg
  36. 36. Using an Envelope  Allows you to change parameters over time  Key frames for parameters, rather than for the object itself  Any time you see an E box, that setting can change over time
  37. 37. Make Dino Vanish Over Time  Set the Object Dissolve to 0%  Next to the Object Dissolve box, click on the E to open the Envelope  The Graphic Editor opens up  Looks complicated, but it’s pretty easy
  38. 38. Make Dino Vanish Over Time  Click on the Key icon just under the chart  At frame 120 click on the line  This sets a keyframe for Dino at 0%  No transparency
  39. 39. Make Dino Vanish Over Time  Click another key frame at frame 60  Switch to the Drag icon  Now we are going to change this value
  40. 40. Make Dino Vanish Over Time  Drag this key frame up to 100 %  You should see the opacity ramp up from 0% from frame 0 to 100% at frame 60, then back down to 0% at frame 120.  If not, use the drag tool to make these settings
  41. 41. Make Dino Vanish Over Time  Drag the Timeline slider and notice how your object fades out to nothing and then reappears  Scary!!
  42. 42. Turning Off Envelopes  Not as easy as Textures  Hold the Command key and then click on the E box  Choose Remove Envelope  You can turn it back on by clicking on the E again if you want
  43. 43. Make Dino Vanish Over Time  Hold down the Command key and click on the envelope box  Choose Remove Envelope  Drag the Dissolve slider back to 0%
  44. 44. Other Render Settings  Unseen by:  Makes the object unaffected or unseen by various effects  Can even be hidden from the camera  Shadows  Turn on or off the ability to cast a shadow or receive a shadow from something else
  45. 45. Edges Tab  Polygon Size  Changes how big the polygons APPEAR to the camera  Too small or too big = interesting effect  Edges  Highlights different lines that make up the object
  46. 46. Tinker with Polygon Size  Drag the Polygon Size slider to 50%  Render the frame and check it out  Notice that you can envelope this effect to have the polygons change size over time
  47. 47. Tinker with Polygon Size  Select over 50% and change the size to 1000%  Render the frame and check it out  Polygons are too big making Dino chiseled
  48. 48. Bring the Polys Back to Normal  Drag the Polygon slider to change the size back to 100%
  49. 49. Paint the Edges  Check the Silhouette Edges box  Under Edge Color, choose a color  Render a frame and check it out
  50. 50. Paint the Edges  Uncheck Silhouette  Select Other Edges  Change the Size to Medium  Change the color and render a frame to check it out
  51. 51. Just the Edges  On the top change the polygon size to 1%  Render the frame and check it out
  52. 52. Take a Picture for your Homework  Save your rendered frame as a JPG to your desktop and call it Edges.jpg
