Basic Node Setup
The output of a Catcher node should be connected to the material input of your 3D geometry
node. A camera is set up as a proctor with an image connected to the camera’s image input.
When the camera is set to texture projection mode, the Catcher node is used to determine
which geometry receives the texture.

Inspector
Controls Tab
The Options in the Controls tab determine how the Catcher handles the accumulation of
multiple projections.
Enable
Use this checkbox to enable or disable the node. This is not the same as the red switch in the
upper-left corner of the Inspector. The red switch disables the tool altogether and passes the
image on without any modification. The Enable checkbox is limited to the effect part of the tool.
Other parts, like scripts in the Settings tab, still process as normal.
Color Mode
The Color mode menu is used to control how the Catcher combines the light from multiple
projectors. It has no effect on the results when only one projector is in the scene. This control is
designed to work with the software renderer in the Renderer 3D node and has no effect when
using the OpenGL renderer.
