VisArea

The vis area object is used to define indoor areas for culling and optimization purposes, as well as lighting. Objects inside a vis area won't be rendered from outside and vice versa, this can help with performance immensely.

Vis areas also can be setup to occlude certain lighting elements such as the sun, which gives flexibility in setting up lighting for your indoor areas.

  1. In Rollup Bar, on the Objects tab, click Area, VisArea.

  2. Place the vis area object around the desired area in your level and set the Height parameter value. Keep the shape of the vis area as simple as possible.

  3. Ensure everything related is inside the vis area.

  4. Enable Snap To Grid.
