  • Sampling mode: the sampling mode to use between

    • Regular: Samples raw values and does not perform any runtime conversion

        • Green

        • Blue

        • Average RGBA (default)

      • Density power: Exponantiates the density

    • Both: Samples both raw values and density of the texture

  • Allow texture conversion at runtime: Enable to allow PopcornFX to convert the texture at Runtime, if
