Lighting

When the Lighting section is opened and the Strength is not 0, there are two extra tools that open on the image.

One is the directional light and this is shown by a Sun shape which can be dragged around the image to adjust the direction of the light.

The other works like the extend areas tool and appears like a hand drawn arrow, and will drag the light from the place where you first click, across the area where you then drag the tool.

This is to help make the areas of lighting the same where they should be the same, for instance, on one surface at the same angle.

The lighting section contains a tab with Presets and a tab with sliders.

Adjusting the Strength slider opens up the other options.

The options are:

Lighting color

Shadows – Opens up the blocks of colors for the shadows and the sliders to adjust to exactly the color that you want.

Highlights – Opens up the blocks of colors for the Highlights and the sliders to adjust to exactly the color that you want.

Cloud Shadows

Cloud shadows are shadows cast by the sun onto the ground. These can be used to make a flat landscape more interesting.

Shadow Type – Adrop down to select different patterns of clouds to cast onto the ground.

Shadow scale – Allows you to increase or decrease the amount of shadows cast onto the ground. When it is 0, then this has no effect.

Angle – Rotate the shadows cast onto the ground.

Buildings

This section only appears when you have dragged a building label onto the picture.

Relight as facade – Button to adjust the lighting so that all buildings are lit as if theywere vertical flat planes. Turn on or off.

Soften Lighting

This gives you a slider for each section that decreases the lighting in each of the areas.

Lighting Texture

This gives you a slider for each section that allows you to change the roughness of each area. Rougher areas will bring out more texture, especially when the light is glancing.

Reset Section and Save Sliders

At the bottom of each section are the buttons for Reset Section, and Save Preset.

Save a preset for future use by clicking Save Preset. This opens a box to type a preset name. Click OK to save it as a Preset in that section. Click Cancel to exit the Save Preset box.

Click Reset Section to revert all slider values to 0, undoing all of your changes to that section.

Tip: Toggling the power symbol to the right of a section heading lets you turn your changes on and off without permanently undoing them. This is useful if you want to review your edits.
