Camera

The Camera section has two distinct uses:

• Filter instances not visible by the camera or far away from it, using Exclude non-visible and Distance clipping.

• The selected camera position is also used by LODs to determine when to switch from one LOD to the next.

Scene camera

The current view is used by default. But since its position changes every time you move in the SketchUp viewport, you probably want to select a scene whose Camera Location will be used.

Exclude non-visible

Discards instances that are not in the camera's field of view. This is particularly useful to boost performance by preventing the generation of instances that will not be visible by the render camera anyway.

Parameter	Description
Expand FOV	This expands the field of view of the camera when determining if an instance is visible or not. This is useful when we have large objects whose parts could be visible by the camera even though their origin is not. Note that the actual camera FOV is not affected.
Camera offset	Moves the camera backward or forward when determining if an instance is visible or not. The use-case is the same as above, but for objects that are originally behind the camera. Note that the actual camera position is not affected.

Distance clipping

Discards instances that are far away from the camera. This is particularly useful to boost performance by preventing the generation of instances that are too far away from the render camera to be visible.

Parameter	Description
Distance	Distance from the camera beyond which instances are discarded
Falloff distance	Length of the falloff that interpolates density near the above distance.
Falloff curve	See the Falloff Curves section.
