The Camera Cull operator can be used to cull particles from display/render/export that are outside of a camera’s view frustum.
Delete: when enabled, culled particles will be deleted. When this operation is selected, the Camera Cull operator has a direct, history-dependent impact on the simulation.
Hide: when enabled, particles will be hidden from display/render/etc, but not deleted from the flow. When this operation is selected, the cull process happens as a post-effect and does not directly affect the simulation.
Test TRUE: when enabled, culled particles will have their output condition set to TRUE. When this operation is selected, the Camera Cull operator has a direct, history-dependent impact on the simulation.
Frustum cull: particles will be culled based on whether or not they are inside of a camera’s frustum.
Distance cull: particles will be culled based on whether or not they are within a certain distance to an object.
In “distance cull” mode, any object can be used - not just cameras.
Distance: the minimum distance to an input object that a particle must be in order to be culled.
Invert: inverts the effect of the distance cull (the distance value becomes a maximum value rather than a minimum value).
Display: when enabled, culling will affect particle display.
Render: when enabled, culling will affect particle rendering.
Export: when enabled, culling will affect particle exports.
Particle Interface: when enabled, culling will affect particle interfaces.
