Section Plane
The Iray Section Plane is a helper object for placing section cuts through an entire 3ds Max scene. This creates an infinite
planar cut in the Iray rendering, but is shown as a simple rectangular grid in the viewport with arbitrary size and spacing.
Multiple Section Planes can be combined to cut the scene in several places.
Adding a Section Plane
To add a Section Plane, from the dropdown on the Tool panel under Create > Helpers, select
Iray+. On the Object Type rollout, select Section Plane:
Parameters
Properties:
- On: toggles the section cut in the rendered image. Disable this to show the full scene.
- Clip Light: when enabled, the part of the scene hidden by the section cut is invisible to the camera,
but still affects lighting in the scene. Use this to see inside a model whilst preserving the original scene lighting.
When disabled, the cut mesh is completely hidden by the section and does not affect lighting in the scene.
- Flip Direction: when enabled, this reverses which side of the Section Plane is hidden in the rendering.
Grid:
- Length: sets the length of the helper shown in the viewport.
- Width: sets the width of the helper shown in the viewport.
- Spacing: sets the size of the grid shown within the helper in the viewport.
Display:
- XY Plane/YZ Plane/ZX Plane: sets the initial orientation of the section cut.
✱ Note: standard 3ds Max transforms (move, rotate, scale) and animated
transforms are supported.
