Soft Clip placed between a Merge 3D and a Renderer 3D node
Inspector
Controls Tab
The Controls tab determines how an object transitions between opaque and transparent as it
moves closer to the camera.
Enable
This checkbox can be used 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 of
the tool. Other parts, like scripts in the Settings tab, still process as normal.
Smooth Transition
By default, an object coming closer and closer to the camera slowly fades out with a linear
progression. With the Smooth Transition checkbox enabled, the transition changes to a
nonlinear curve, arguably a more natural-looking transition.
Radial
By default, the soft clipping is done based on the perpendicular distance to a plane (parallel
with the near plane) passing through the eye point. When the Radial option is checked, the
Radial distance to the eye point is used instead of the Perpendicular distance. The problem with
Perpendicular distance soft clipping is that when you move the camera about, as objects on the
left or right side of the frustum move into the center, they become less clipped, although they
remain the same distance from the eye. Radial soft clip fixes this. Sometimes Radial soft clipping
is not desirable.
For example, if you apply soft clip to an object that is close to the camera, like an image plane,
the center of the image plane could be unclipped while the edges could be fully clipped
because they are farther from the eye point.
