Here are described the settings and best practices to setup beautiful real-time shadows in Verge3D for 3ds Max.
Shadows can be enabled/disabled for each individual light using 3ds Max's native panels. Supported shadow settings are highlighted with green.
The checkbox On must be enabled and Shadow Map must be selected in the dropdown for shadows to appear in Verge3D.
Falloff/Field defines the shadow volume (the less the better).
Bias can be tweaked until you get rid of self-shadow artifacts and/or the peter-panning effect.
Size controls how big is the shadow texture (trading between speed and quality).
Sample Range controls the blurriness ratio for shadows.
Absolute Map Bias enables Bias to be calculated independently on the scene size.
You can also enable and disable receiving and casting shadow on ber-object basis.
You may check out the following video explaining how to setup shadows in 3ds Max.
