INSIDE 3DS MAX® 7 [Electronic resources] نسخه متنی

1.

Open up a new 3ds max 7 scene, and, in the Top viewport, create a Tube primitive with the following dimensions:

• Radius 1 = 3000

• Radius 2 = 29000

• Height = 5000

• Cap Segments = 11

2.

Next, apply an Edit Poly modifier to the tube. Enter Polygon sub-object mode and marquee-select the whole bottom of the tube in the Front viewport. Then click the Grow button in the Selection rollout several times, until every face is selected except for the top cap segments of the tube. Delete the selected polygons. This leaves us with only the cap segments on the top of the tube (Figure 8.26).

3.

Rename the tube LoRes_valleyfloor. Merge in the LoRes_herocliff model from your previous file or from Landscape_CliffDisplace.max. Move the LoRes_valleyfloor object down so that it intersects just above the bottom edge of the cliff (Figure 8.27).

4.

Quickly map the LoRes_valleyfloor object by putting a UVW Map modifier on it, with the Mapping type set to Planar and aligned with the Z axis.

5.

Right-click the LoRes_valleyfloor object, and in the bottom right Quad menu, choose Convert To > Convert to Editable Poly.

6.

Right-click the LoRes_valleyfloor object again, and choose Clone from the bottom right Quad menu. Make a copy of the LoRes_valleyfloor object and rename it HiRes_valleyfloor.

7.

Open the Material Editor, go to an empty Material slot, and click the Get Material button. In the Material/Map browser that appears, choose Mtl Library in Browse From and click the Open button in the File section. Find the HiRes_valleyfloor.mat file on the DVD and open it (Figure 8.28).

8.

Double-click the HiRes_valleyfloor material to open it in the empty material slot. Apply the HiRes_valleyfloor material to the HiRes_valleyfloor object. Then apply a Displace Mesh (WSM) modifier to the HiRes_valleyfloor object with the following settings:

• Custom Settings

• Subdivision Displacement

• Spatial and Curvature

• Edge, Distance, Angle = 30, 30, 30

• Delaunay Subdivision Style

9.

Wait for the displacement to display on the HiRes_valleyfloor model. Once you can see the displacement, go back to the LoRes_valleyfloor model and add some extra edge loops with the Ring and Connect tools, as we did with the cliff. Then raise the geometry on the LoRes_valleyfloor to roughly match the raised displacements on the HiRes_valleyfloor model (Figure 8.29).

10.

Drag the HiRes_valley floor material to an empty slot, and rename it LoRes_valleyfloor. Delete the Mix map from the Displacement map slot of this material, and then apply it to the LoRes_valleyfloor model.

11.

Repeat the same Render To Texture process that we used on the herocliff models to generate Normal maps. Then hide the HiRes_valleyfloor to see how the Normal-mapped LoRes_valleyfloor looks. Open the file Landscape_ValleyFloor.max to see how it compares with your file.

12.

Open Landscape_Terrain.max to see how the cliff has been modified and duplicated to populate the environment.
