    How to calculate the shadow bias in shadow maps(PSSM)

    I implement the Parallel-Split Shadow Maps into my scene.
    My scene seems to have the moire patterns. I think that I must to calculate the shadow bias individually in each split?
    But I cannot find the algorithm and article of shadow bias. Colud somebody ever find the shadow bias's data?

    There's no formula for the shadow bias. You simply have to manually try more values, and choose one that looks best for your scenes / object sizes.
