    • Field Detail

      • anisotropy

        public int anisotropy
        Sets the number of anisotropic samples to use when sampling a VSM shadow map. If greater than 0, mipmaps will automatically be generated each frame for all lights. The number of anisotropic samples = 2 ^ vsmAnisotropy.

      • mipmapping

        public boolean mipmapping
        Whether to generate mipmaps for all VSM shadow maps.

      • msaaSamples

        public int msaaSamples
        The number of MSAA samples to use when rendering VSM shadow maps. Must be a power-of-two and greater than or equal to 1. A value of 1 effectively turns off MSAA. Higher values may not be available depending on the underlying hardware.

      • highPrecision

        public boolean highPrecision
        Whether to use a 32-bits or 16-bits texture format for VSM shadow maps. 32-bits precision is rarely needed, but it does reduces light leaks as well as "fading" of the shadows in some situations. Setting highPrecision to true for a single shadow map will double the memory usage of all shadow maps.

      • minVarianceScale

        public float minVarianceScale
        VSM minimum variance scale, must be positive.

      • lightBleedReduction

        public float lightBleedReduction
        VSM light bleeding reduction amount, between 0 and 1.
