By changing it, you can create a different pattern of randomness in your image. Randseed determines the starting state of the random number generator. This creates a groove-like effect in the final texture which can be useful for some applications.

That is, all values in the noise that are mid grey or darker will be inverted and then the entire texture is resampled to fill the full black-to-white range.
By checking 'alpha' you will write noise into the alpha channel. By checking 'color', you will write different noise textures into each of the red, green and blue channels. By default a black and white texture will be generated (ie, the red, green and blue channels are all set to the same value and the alpha channel is solid white). Beauty that can be found, even in something that looks somber at first glance. It might not be the best soundscape to listen to when you have anxiety problems, though you may also use it. Less attenuation will make the coarser levels more prominent, giving you a rougher look.Ĭolor and Alpha determine which channels in the final image have unique noise generated. This soundscape was initially intended for Role Play Gamers: a dark mood setter that they often enjoy. Blending several layers of noise can produce a cloudy effect.Īttenuation controls how multiple levels are mixed. Levels will blend extra levels of noise into your texture, with each additional level half the resolution of the previous one. For best results, use numbers that are powers of 2 for the image width, height and cell spacing. The final image will tile seamlessly if the width and height of the image are whole multiples of the cell spacing. By adjusting the spacing, you can change the coarseness of the generated texture. Perlin noise is made by blending together gradients that are evenly spaced apart in a grid. Width and Height determine the width and height of the final image in pixels.Ĭell size determines the coarseness of the image.
