Cast Shadows

When this option is set, the object will cast shadows onto other geometry/terrain/etc.

Global Illumination

Enables/disables voxelization for GI (this affects indirect occlusion from an object).

Support Second VisArea

Normally, objects are considered to be in only one VisArea.
This option allows them to be added to multiple VisAreas (if their bounding box overlaps them), this does have a performance cost.
Without this option, some large objects may not be displayed when viewed through portals (in certain situations).

Outdoor

When enabled, the entity ignores the use of VisAreas in the level. Multiple Vis Areas can be combined to define the points from where the would be visible/invisible. For more information, please see the Vis Area page.

Rain Occluder

Set the brush to occlude rain, this works in conjunction with the Rain Entity.
If your level does contain rain, you should set this wisely as there is a limit of 512 objects that can occlude at any given time.

View Distance Ratio

Defines how far from the current camera position the object can be seen.

Exclude From Navigation

When this option is set, the object will not be considered as a part of the AI triangulation system. This ensures that the geometry of the object will not contribute to NavMesh generation and it will not generate any NavMesh on top of the object, or any hole in the NavMesh where the object is placed.

AI Hideable

When this option is set, AI will use this object as a hiding spot (using the specified hide point type).

No Dynamic Water

Avoids boolean-merge on any surrounding static that intersects with the first vessel.

No Static Decals

When this option is set, decals will not project onto the object.

Occluder

Used for the construction of a level occlusion mesh.
