The Precompute tab allows you to perform a full, partial, or system precompute. The tab is displayed when you have loaded a scene.

Full precompute	Run the full lighting precompute process on the currently loaded scene.
Partial precompute	Precompute for visualisation modes only. Enlighten performs a partial precompute of the currently loaded scene up to and including clustering. This allows viewing of input densities, atlas packing and mesh projection. Lighting is not available.
System precompute	Do a partial precompute of the currently loaded scene including geometry packing, system generation and system packing. Lighting is not available.
Forced precompute	Perform the precompute from scratch disregarding existing data.
Distributed precompute	Pass the precompute tasks to IncrediBuild for remote execution. The precompute results are identical to a local build. Requires IncrediBuild version 3.50 or later on the system PATH, and 4.60 or later to distribute the 64-bit version of the tools.
Low memory precompute	Serialises high memory precompute tasks. The execution of multiple tasks at the same time may consume too much memory for very large scenes.
Include console targets	Precompute the scene for console targets. If not required, disable this for faster precomputes.
Include mobile targets	Precompute the scene for mobile targets. If not required, disable this for faster precomputes.
Open precompute log file	Open the log file for the previous precompute. Only available after a precompute has been launched during this run of GeoRadiosity.

After you launch the precompute, if Distributed precompute was selected, the IncrediBuild window is displayed. If Distributed precompute was not selected, the GeoPrecompMonitor is displayed.

GeoPrecompMonitor provides a visual representation of the progress of the precompute process.

The Vis tab displays colour-coded precompute progress bars grouped by Enlighten system.

Green indicates success.
Yellow indicates a warning.
Red indicates an error.

You can zoom into and out of the *Vis* tab using the mouse wheel.

The Log tab displays precompute log information. This information is written to a date and time stamped log file in the scene folder. For example:

..\Samples\Assets\Arches\Precomp_Arches_101029_112150.log
