Culling Material Effect

  • Supported Platforms
  • Supported Engine Versions


VR Demo:


This Effect is useful for Technical View of Objects, where it is needed to look through 3D Geometry to see the underlying parts of the Construction/Product.

This Effect has a Material Function and can easily be implemented into existing or custom Materials. There are already Material instances in which you can load your Textures or values.

You have two choices of Culling objects, one is a simple Cutting Plane and the other one is a Sphere Volume. Both methods are fully interactive, work simultaneously and can also be animated by Sequencer. The Sphere Volume can be bound to the Viewers Camera to allow the viewer to "dive" into a model.

There are two VR Example Maps, one demonstrates the Culling Effect around the View and the other one lets you pickup and place a Cutting Plane and a Sphere.
