Common Controls
Settings Tab
The Settings tab in the Inspector is duplicated in other 3D nodes. These common controls are
described in detail at the end of this chapter in “The Common Controls” section.
UV Map 3D [3UV]
UV Map 3D Node Introduction
The UV Map 3D node replaces the UV texture coordinates on the geometry in the scene.
These coordinates tell Fusion how to apply a texture to an object. While it is possible to adjust
the global properties of the selected mapping mode, it is not possible to manipulate the UV
coordinates of individual vertices directly from within Fusion. The onscreen controls drawn in
the viewers are for reference only and cannot be manipulated.
Camera Projections with UV Map 3D
The Camera Mapping mode makes it possible to project texture coordinates onto geometry
through a camera. Once you select Camera from the Mapping mode menu, then connect the
Camera 3D node that you want to use to create the UV coordinates.
Note that this does not directly project an image through the camera. The image to be
projected should be connected to the diffuse texture input of whatever material is assigned to
the objects. When the texture is applied, it uses the UV coordinates created by the camera.
Because this is a texture projection and not light, the Alpha channel of the texture correctly sets
the opacity of the geometry.
See the Camera 3D and Projector 3D nodes for alternate approaches to projection.
The projection can optionally be locked to the vertices as it appears on a selected frame.
This fails if the number of vertices in the mesh changes over time, as Fusion must be able to
match up the mesh at the reference time and the current time. To be more specific, vertices
may not be created or destroyed or reordered. So, projection locking does not work for many
particle systems, or for primitives with animated subdivisions, or with duplicate nodes using
non-zero time offsets.
NOTE: The UV Map 3D node does not put a texture or material on the mesh; it only
modifies the texture coordinates that the materials use. This may be confusing
because the material usually sits upstream, as seen in the Basic Node Setup
example below.
