Auto Exposure
Select the Auto Exposure check box to render the scene with balanced
brightness and contrast. This is essential when using physically accurate
lighting, such as a Sky or Sun light. If adding either of these lights to your
scene, you will be prompted to turn Auto Exposure on, if it is not already.
Use Presenter Texture Space
Texture space describes the way in which a texture is applied to an item. For
example, applying a cylindrical texture space to a pipe will cause textures on
the pipe to be rendered more naturally. An item’s texture space may have
been assigned from the original CAD application and stored in the native
CAD file, or set up within the Presenter window with the options of Box,
Plane, Cylinder, or Sphere. The Explicit option allows a user-defined
texture space to be applied and will be available if the item had a texture space
applied to it in the original CAD application. Each texture space option applies
some imaginary bounding geometry around the item and “shrink-wraps” the
texture as best it can to the geometry underneath this bounding geometry.
If you’ve applied a texture to an item, the Presenter window will attempt to
work out the best fit from the four texture spaces available. If this isn't what
you intended, then you can then edit the texture space.
