Render Kill List

The Render Kill List is a list of Entity ids which, even if they've been simulated and exported in the Simulation Cache Files, will be removed from the rendering. Those ids are stored in the Simulation Cache Layout Modification History files. The entities in the Kill List are displayed as uncolored characters.

This list can be painted with the Kill List painting mode of the Paint Tool or edited with the Simulation Cache Layout Tool using  buttons.
