VRML 1 Import
Determines whether and by how much VRML 1 files are scaled when they are loaded.
If Optimize Hierarchy is enabled, the scene structure is optimized once the VRML1 file has been loaded. Superfluous dummy objects are removed and the object hierarchy is optimized. This creates a clearer overview, helping you to work more quickly.
The mesh exported by some NURBS modeling applications tends to be prone to software shading errors. With the VRML 1, VRML 2 and Wavefront formats, you can now include vertex normals in the file provided that you have activated vertex normals in the modeling application. Vertex normals are normals for points. Depending on how many surfaces are involved, a point may have multiple normals.
With the help of these vertex normals, CINEMA 4D is able to produce good shading despite the sub-optimal mesh. The vertex normals are stored in a Normal tag (see below).
CINEMA 4D is able to display and correctly render the imported objects thanks to these Normal tags. Keep in mind that if you edit the points of such imported objects, the Normal tags will no longer work properly and the mesh may produce shading errors. You can, however, move, scale and rotate the object itself and the tags will still function correctly.
If you delete the Normal tag, the standard shading will be used instead.
