![]() ![]() Leaving the value empty will use the randomly-assigned seed value on layer creation. You can input any value or text here, and it will always try to use this value to generate the random values with (which then are always the same for a given seed). This makes the noise have a rectangular appearance. I’ve never personally used the Weasyl site before but it. It has a visual tutorial along with direct download links on the page. But this page seems like the easiest brush pack to start with. The ratio of the waves in the x and y dimensions. Note: I found a few different brush packs with the same name so if you Google search easy paint tool sai brushes you might find more to work with. Higher frequency results in a finer noise pattern. The frequency of the waves used to generate the pattern. Whether or not to force the pattern to loop. Experimenting with different combinations can be fun and produce interesting results! Looping For texture artists, this can be a useful utility when combined with a gradient map filter layer to provide color diversity to a looping texture.įor traditional artists, simplex noise layers can be converted to selection masks to create brush transparency dynamics and masking effects. It becomes even more expressive when combined with the levels adjustment layers. One of these is to create interesting looping patterns, achieved by stacking multiple simplex noise fills with different blending modes. There are a few different use cases for simplex noise. You can read more about OpenSimplex here. Since OpenSimplex noise is important to texture generation, this fill layer has the option OpenSimplex has less dimensional artifacts (the subtle “checker” texture often found high frequency Perlin noise) and is a ubiquitous open standard. OpenSimplex is different from the more common Perlin noise (often named ‘clouds’ in other software) and also different from Improved Perlin noise. This fills the layer with generated OpenSimplex noise. ![]()
