Shadows: OverviewMonday, November 25, 2013 5:12 PM
Paradise Sandbox uses a robust shadow system to achieve real-time high-quality shadows.
Shadow parameters are customizable per-scene, all shadow-related properties can be changed using the 'Property Editor' when a scene has been selected using the 'Project Explorer':
Note 1: these shadow properties are effective for the scene main light, named 'MainLight', and which is already configured in all presets and sample scenes that come with Paradise Sandbox
Note 2: in future versions 'Spot lights' are going to be added and each spot light will be able to cast shadows
Quality of shadows (resolution) , from Very low to Extra high. Better quality means more resolution ,so in small scenes (for example indoor rooms) which MainLight's attenuation distance is about 15-30 meters, even Low or Medium quality will result in aceptable shadows. On the other hands, open-door scenes (where MainLight's attenuation distance is ~150-300 meters) will need High or Extra high quality in order to look great.
Power of the soft shadows effect (smooth borders). Big values can lead to noising artifacts.
Bias applied to receiver surfaces in order to avoid self-shadowing acne problems. There are 4 bias values, each one for each region of the shadow field: the first one affects the region near the camera while the 4th one affects the fartest region of the scene.
Similar to Bias but its effect is multiplied by the dot product between the surface's normal and the direction incidence.
Note: a very important parameter for the final visual result of shadows is the MainLight's attenuation distance.
