Wizard

Lightscape comes with a very powerful wizard that will calculate all these values for you automatically. To start the wizard, select Process>Parameters from the menu and click on the Wizard button.

These calculations are based on an overall quality index (from 1 to 5), lighting conditions that you need to specify and a number of other factors (such as number of faces, etc.). Be aware that a quality index of 3 is usually very high, and you should try with lower values when testing.

Parameters

Process

• Shadows: enables shadows from light sources.
• Direct only: only direct light sources will cast shadows.
• Daylight: includes daylight calculations in the solution file.
• Sky light accuracy: sky light is computed by a mesh representing the sky dome. This slider controls how fine this mesh is.
• Daylight through openings only: daylight will be calculated only through those surfaces indicated as windows or openings in the model.

Receiver

• Min/Max: minimum and maximum size of the sides of the mesh elements.
• Subdivision Contrast Threshold: If the lighting values on the vertices of a single surface are greater than the threshold, lightscape will subdivide the mesh into smaller patches.

Source

• Min/Accuracy: It controls the minimum size of the elements emitting light (both direct and indirect light sources) and the accuracy of the subdivision.
• Shadow grid size controls the number of rays between a light source and a receiver.
