Preferences can be opened from menu Extensions -> De Luminae ->
[Extension name] -> Preferences.
Some parameters are common to all extensions, others are specific. They are
classified in groups:
To restore the default value of a parameter: click on the arrow to
right of value.
To restore the values of all the parameters of the current tab:
click on the "Defaults" button.
Global preferences are common to all extensions.
In trial version of extension most options are set to default values. For
more details read License information.
Number of parallel calculations - Maximum number of processes in
parallel on the computer. The maximum is the number of CPU cores.
Show warning messages - Switch on/off warning messages.
Show switching extension message - Switch on/off warning messages
before extensions are swiched.
Show "Admin tools" menu - Add some advanced tools in menu
(requires restarting SketchUp).
Export / import preferences: allows you to save
preferences and reload them, possibly on another
instance (another machine or other version of SketchUp).
Show calculation log: displays the file "log.txt"
which lists the operations performed and the elapsed time. This
file is created at the end of the calculation.
Show cache size: displays the disk space used by
the cache for each plugin. The number of calculations kept in
cache is adjustable for each extension (see below).
Enable automatic check for updates - Enable extension to
automatically check to De Luminae site if new version is available. If
new version is available user is informed, but not forced to download and
Sound notification - Play a sound when computation is done and
duration in seconds is greater than value. Set to 0 to stay always
Date format - Select the display format for dates.
Display time zone abbreviations - Select the display format for
Abbreviations of time zones - Customize the abbreviations of time
Calculation periods - Customize calculation periods (seasons
Default reflectance - Reflectance of default material for surfaces
without defined material.
Take into account north angle - Take into account north angle
parameter (shadow_info['NorthAngle']) for extensions involving Sun
position (Sunexposure, Watt, Daylight Autonomy, Daylight Factor,
Cache directory - Folder used for temporary computations and
Some parameters are present on all the extensions:
Show report - Automatic report display after each calculation.
Algorithm for false color textures - Setting the generation of
textures. The indicators are calculated on a grid of sensors
according to the Level of detail , then these values are
interpreted for visual representation. Several algorithms are
available, see page Interpolation
Maximum texture size - Adjust the maximum size of textures
generated. Warning: for size of 8192 or above, rendering time
and memory usage increase a lot.
Texture smoothing - Adjust the smoothing level of the
Use fixed size for snapshot images - Fix the size of snapshot
Use fixed size - Width of the fixed size image (1600 pixels by
Don't use fixed size - The size of the exported image will
correspond directly to the size of the model on the screen.
The default values for these settings should be appropriate for most
Min face area - Minimal surface area, below which surface is
skipped as extremely small. If this limit is set to zero, surfaces can
still be discarded by the threshold distance to borders.
Area limit for single sensor - Area below which a single sensor is
generated for the surface.
Virtual surface offset - Offset default value for virtual
Coverage area of sensors - Assign to each sensor the area
corresponding to the nearest points of the plane (diagram of Voronoi).
The traditional alternative is to consider that every sensor represents
the same surface which can lead to anomalies (corner sensors).
Maximum scale in px/m - Texture resolution in pixels per meter.
Actual textures resolution is limited by both this setting and maximum
textures size. For a large model (town planning), use a low value, for
example 10 pixels / meter.
Interpolation density - Setting the number of interpolated points
for each sensor.
Warning if many surfaces - Warn if surfaces to calculate is bove
Cache size - Number of calculations kept in the cache. The cache
allows to accelerate successive calculations on the same project.
Each extension has its dedicated cache. To clear the cache, put this
value to zero and start a calculation.
Complex period - Definition of the complex period used in
'complex' duration mode. See complex
This section provides access to internal software settings. These parameters
should not be changed without support.
