Using Video Post to Make Jewels Sparkle in 3DS Max

Using Lens Effects to Make Lights Sparkle

To make these jewels really appear to sparkle, you will now add a light to the scene. The light will use Lens Effects to create add some of the optical effects you see in jewelry advertisements.
  1. Select the Create tab.
  2. Select the Lights icon.
  3. Choose Omni.
  4. Click to create a light near the upper right corner of the cross. Move the light down in the Front view until it rests just above the cross. The precise position of the light isn't important, as long as it is close to, and above, the cross.

  5. Select the Modify tab.
  6. Under the Atmospheres and Effects rollout, choose Add.

  7. Select Lens Effects, then choose OK. Lens Effects let you apply optical effects to lights.
  8. Select Lens Effects under the Atmospheres and Effects rollout.
  9. Choose Setup.
  10. In the window that pops open, Under the Lens Effects Parameters rollout, choose Ray, then the button to apply this effect to the light.
  11. Choose Star then the button to apply another effect to the light.

  12. Render the Perspective view again.

    Tip
    You can use the materials assigned to the objects in this scene to dress up your own objects. To add these materials to your own material library, just select the desired sample sphere in the Material Editor and choose the Put to Library button.


You will find our version of the finished project in 0331d.max in the self-extracting executable m0431a.exe.

Creating Refractive Materials in 3DS MAX

DO NOT DUPLICATE. DO NOT DISTRIBUTE. CONTENT WATERMARKED.

Now that you have created the jewel geometry, you must create the refractive raytraced material that that will make it look like a jewel.

This material will be highly reflective, transparent and have a refraction index. These are the characteristics of jewels in the real world. Raytraced materials are useful because they more accurately reflect the way light and materials work together. They are particularly useful when you are creating objects with optical effects, like mirrors, glass objects, jewels, water, and so forth.

  1. Type M to display the Material Editor.
  2. Select an unused sample sphere.
  3. Select the word Standard to the right of the word Type. This lets you specify the kind of material you want to create.
  4. Double-click Raytrace from the list of material types.
  5. Select the rectangular color swatch just to the right of the word Diffuse.
  6. Use the Color Selector to create a dark green color. This specifies the color of the object in the unshiny areas.
  7. In the Specular Level spinner, type 150. This makes the object have small specular highlights.
  8. In the Glossiness spinner, type 60. This makes the specular highlights very bright.

  9. Select the Transparency color swatch and make this color a lighter green.
  10. Choose Close to exit this window.
  11. In the Index of Ref. spinner, type 2.149. A high index of refraction makes it look as if light were bouncing around a great deal inside the object. Check out the MAX help system, under the topic Raytrace Material, for a list of refraction index values associated with various kinds of materials.
  12. In the Material Editor, select the 2-Sided checkbox. This makes the faces inside the object reflect and refract light as well as the outside faces.
  13. In the scene, select the cross, if it's not already selected.
  14. Select the Assign Material to Selection icon in the Material Editor. You can drag and drop the sample sphere onto the cross, if you prefer.
  15. Close the Material Editor.
  16. Select the Display tab.
  17. Choose Unhide All.
  18. Adjust the position of the cross, if desired.
  19. Render the Perspective view.


You will find our version of the project to this point in 0631c.max in the self-extracting executable m0431a.exe.

Creating Jewels that Refract Light using Ray Tracing in 3DSmax

DO NOT DUPLICATE. DO NOT DISTRIBUTE. CONTENT WATERMARKED

Introduction

In this project, you create a faceted cross by modifying a geosphere. After you create the cross, you create and assign a ray-traced material to the cross to make it look like it is carved from an emerald.

In this project, you learn how to:

  • Turn geospheres into jewels.
  • Shape geospheres using an FFDBox modifier.
  • Create a ray-traced material that refracts light like a green diamond.
  • Use lens effects to make a light sparkle.

This project also contains a diamond, ruby and sapphire material you can use in your own images and animations. If you wish, you can add the materials in this scene to your own material library.

Creating Jewels with Facets

The easiest way to create a jewel is to start with a geosphere. Most jewels have surfaces composed of facets. There are lots of evenly and symmetrically distributed facets on a geosphere. You can use tools like FFDBox and Edit Mesh to move the vertices of the geosphere to create the desired effect.

Prior to proceeding with this project, open 0631a.max which can be found in the self-extracting executable m0631a.exe. To unpack the source files, just transfer the .exe file to a folder on your local hard disk. From the Windows Start menu, choose Run. Select the .exe, then choose OK. Specify where you would like the source files placed.

Follow these instructions to create a faceted cross.

  1. Select the Sphere in the Front view.
  2. Select the Modify tab.
  3. Remove the check from the Smooth checkbox on the Modify command panel. This tells 3D Studio MAX not to smooth away facets on the sphere when it renders.
  4. Select the Octa checkbox. This arranges the faces of the sphere in a common jewel cut. You can experiment with other options if you like.
  5. On the Main Toolbar, choose the Select and Uniform Scale icon, then drag down to select the Select and Non-Uniform Scale button.
  6. Drag down on the Z spinner located under the viewports to flatten the sphere.
  7. In the Modify command panel, from the Modifier List select the FFD (Box) modifier. You will use this to modify the sphere.
  8. In the command panel, select the Set Number of Points button.
  9. Type 6 in all spinners to specify the number of control points on the object.
  10. Choose OK to exit this window.
  11. In the command panel, in the Modifier stack, select the + associated with the FFD(box) 6x6x6 entry.
  12. Select Control Points from the list of sub-objects.

  13. Select two points in the top view to put a window around the four control points indicated in the image.
  14. Select the Non-Uniform Scale icon, if it is not already selected.
  15. Move your mouse onto the band above and to the left of the inner triangle on the scale icon. It will turn yellow. Click and drag on the band to scale the vertices on the X and Y axis, but not the Z axis.

  16. Choose the Select and Move icon on the Main toolbar.
  17. Move the selected points to the position shown in the image.

  18. Repeat this procedure for the remaining corners on the object.

  19. Select, move and scale vertices until your cross looks like the one shown in the image.

  20. Choose the Create tab to indicate that you don't want to move or scale control points any more.

You will find our version of the file to this point in 0631b.max in the self-extracting executable m0631a.exe.

Making Materials Use Material Channels in 3DS MAX - Part 2 of a Free Tutorial

In this lesson you modify simple materials to make them capable of throwing sparks. To do this, you assign a Material Effects Channel to them. You associate this channel value with an effect in Video Post. This is how MAX knows which objects should have the effect.

Prior to proceeding with this project unpack the source files from the m0706a.exe self-extracting executable. To do this transfer the .exe file to a folder on your local hard disk. From the Windows Start menu choose Run. Select the .exe file. Choose OK, then specify where the source files should be places.

  1. Open the 0706a.max file. You will see two ball and coil assembles. If you select the Play Animation icon in the lower right corner of the screen you can watch the two objects, which represent Tesla coils, move toward and away from each other. Between the two objects you will see particle systems that fire particles at one another.

  2. Type M to display the Material Editor.
  3. Select the upper left sample sphere that contains the yellow material.
  4. Select the Material Effects Channel icon, then choose 1. This material has already been assigned to the coils and spheres in the scene.

  5. Use the techniques just demonstrated to assign the Material Effects Channel 2 to the metallic Particle Spark material located in the upper middle sample sphere.

  6. Close the Material Editor.
You will find our version of the model to this point in 0706b.max unpacked from the m0706a.exe self-extracting executable.
