Version 1.2.6 contains three additions and one small change:
Another fall body shape was added - a box with different lengths on all sides.
A custom fall body shape can now be loaded as a DXF-file - see bottom button of fall body shapes.
A grid of fall bodies can be generated and "rained" onto the topography. It could help identifying trouble areas, or potentially water accumulation areas when spheres are used. See the button with the cloud and rain drops to further investigate.
The altialiasing for smoother edges is not automatically activated any more. Press the "Smooth" button when the additional scene quality is required.
Hope you enjoy the new version, let me know what you think. Best regards Frans
