SoftClip
Near-camera fade for 3D geometry
SoftClip fades 3D geometry and particles as they approach the camera, using two distances and a selected distance metric.
SoftClip
Overview
What SoftClip does
SoftClip addresses abrupt disappearance near the camera during flythroughs and particle motion. It operates on classic scene3d and is usually placed before Renderer3D. The input scene must include the Camera3D used as the distance reference.
Transparent Distance defines full transparency near the camera; Opaque Distance defines full visibility farther away. The clear test interval uses 0.5 and 2 units. Between them, the transition is linear with Smooth Transition off and nonlinear with it on.
Radial off uses depth perpendicular to a camera-parallel plane. Radial on uses full distance to the eye point. Off-axis points have different values under these metrics; a wide plane can have different radial distances at its center and edges.
Show In Display Views reveals SoftClip in other 3D views. It is not a 2D-mask visualization. Enable compares the scene with and without the effect while preserving connections and object placement.
For local application, process a branch containing the camera, then merge it with other geometry. Ensure the near plane does not clip the object before the fade. Review RGB and alpha after Renderer3D; the practices have not yet been natively rendered.
When to use it
Hide abrupt appearance or disappearance of objects near the camera.
Soften a camera flythrough of 3D elements.
Prepare a smooth near-camera fade for particles in a 3D scene.
Compare axial and radial distance metrics.
Limit SoftClip to one scene branch.
