Shader Texture Size
Materials with procedural shaders are converted to textures. This value denes the size of these
textures. Note that volume shaders look different when converted to textures.
Create Neighbor Mesh Data (For HyperNURBS)
Enable this option to allow subdivision surfaces and the Toon shader to be used when the le is
imported into Macromedia Director. If you don’t need this functionality, disable the option for a
smaller le size (about 15% to 25% less).
Polygon Front And Back Visible
By default, Shockwave only displays polygons if their surface normals face the camera — polygons
that face away from the camera are ignored and are not displayed; this is to help speed up the display.
Usually this won’t cause problems provided that you’ve aligned the normals of your mesh correctly
and you’re not using alpha or transparency textures.
If you want to use alpha or transparency textures, add a Shockwave 3D Double Sided tag to each
object that uses these textures. Alternatively, enable the Polygon Front And Back Visible option to
make all surfaces double-sided. However, keep in mind that double-sided polygons slow down the
display of the objects in Shockwave. For this reason tags are usually the best option.
If you can’t see the fronts of surfaces in Shockwave, check if the normals in the CINEMA 4D scene
are correctly aligned. Correct them as necessary using the Align Normals and Reverse Normals
commands.
Substitute Group Objects
Null objects in Shockwave are called ‘group objects’. Since group objects cannot be animated in
Shockwave, the export lter converts animated Null objects to dummy mesh objects.
If these animated nulls are converted to mesh objects automatically, what’s the point of the Substitute
Group Objects option, then? If you enable the option, all Null objects are converted to mesh objects,
not just the animated ones. This is useful if you intend to animate the exported scene in Director using
Lingo. You’ll then be able to animate any of the converted Null objects, not just the ones originally
animated in CINEMA 4D.
