Displace A Mesh

Slide 3

During this exercise you'll learn how to simplify a mesh.

  1. Examine the hierarchy.
  2. Right click over Terrain and select Modifiers » SimplifyModifier from the listed options.
  3. This adds a SimplifyModifier to the mesh construction history.
  4. The hierarchy looks like this: This is a picture of the hierarchy.
  5. Right click over SimplifyModifier and select Simplify: 75% from the listed options. This is a picture of the worksheet.
  6. The mesh is simplified but the U/V values have been destroyed.
  7. Right click over Terrain and select Modifiers » PlanarProjectModifier from the listed options.
  8. This adds a PlanarProjectModifier to the mesh construction history.
  9. Right click over the PlanarProjectModifier and select Projection: 16XY from the listed options.
  10. Hold down CTRL and left click the link node named Link: TrailMaterial.
  11. Right click and select Connect Nodes Directly from the generic command menu.
    This connects the PlanarProjectModifier to the link node. The PlanarProjectModifier now affects the UV for all faces in the mesh that use the material indicated by the link node. UV values for faces using different materials are not modified. This will prove very useful.
  12. The hierarchy looks like this: This is a picture of the hierarchy.
  13. Several modifiers have been added to the mesh construction history.
  14. The CalculateNormalsModifier is applied to the mesh before these modifiers.
  15. Left click the CalculateNormalsModifier. Drag it and drop it over Terrain to place it at the end of the list.
  16. If you make a mistake, hit CTRL + Z to undo the change.
  17. The hierarchy looks like this: This is a picture of the hierarchy.
  18. Select Worksheet » Global Edges from the main menu. [ ALT + W + E ]
