==Lighting Settings Controls==

===LED Light Type dropdown menu===: The Illumination light temperature active only when Back Lit is chosen.  Selections are Warm White 2700K, Natural White 4000K (default), Cold White 6500K, Red, Green, Blue, Cyan and Magenta.

===Light Intensity control bar===: Adjusts the strength of illumination when Back Lit.

===Front Lit Button (exclusive)===: Select to preview image as a filament painting (i.e. the print is to be lit from the front).

===Back Lit Button=== (exclusive): Select to preview image as a colored lithophane or a mixed mode filament painting with the light source positioned behind the print.  Used by itself, it does not affect filament layer heights.

===Slicer View Button=== (exclusive): Select to preview the print as it would appear in a properly configured slicer view.  Select Front or Back Lit button to restore to blended view.  As an alternative, press and the scroll control button to temporarily switch to Slicer View while mouse cursor is in the preview window.

===Blending Type dropdown menu===: Select from Filament Painting or Lithophane modes.  Filament Painting is normally the default and sets the Front Lit button to on.  Lithophane mode invokes the Back lit mode and inverts the layer heights of populated filaments (sliders and on Color Core).


==General Options and Operations==

===Remesh=== (momentary): Recomputes the model mesh in the unlikely event that control actions are not properly reflected in the displayed geometry model.  (May be removed in later versions.)

===Wireframe check box===: Changes the preview to show the geometry model's wireframe.  Use Reset View button to restore

===Reset View=== (momentary): Press to restore properly scaled preview after a zoom, tilt or pan operation operation.  Also used to clear Wireframe check box and restore normal preview.

===Describe Button=== (momentary): Opens a pop up window listing the description of the current filaments and layer swaps needed in the slicer.  Note: The information is also written in a [project_name]_describe.txt file when a project is saved.

===Negative Button=== (toggle on/off):  Reverses the heights in the luminance map of an image - ON = dark (low) to light (high).  Off = light (high) to dark (low).  ON is the default setting for a filament painting; OFF for a lithophane.  Selecting Lithophane mode turns this button off, but the button has no impact on Blending Type selection.
