I often say in my courses: there are methods and principles. Who knows the principles always find the solution, but who knows only the methods (tutorials) will have many more problems!<\/p>\n<p>What is the main principle\u00c2\u00a0in this case? <strong>The classic &#8220;noise&#8221; is not suitable to simulate the sea<\/strong> because the sea has some undulations, within which there are other small ripples, within which we have very small ripples &#8230; and so on.<\/p>\n<p>Now that you know this principle, create a new image in Photoshop by clicking: <strong>Filter&gt; Render&gt; Clouds<\/strong>. The result is an image like this:<\/p>\n<p><img decoding=\"async\" loading=\"lazy\" class=\"alignnone\" title=\"texture photoshop\" src=\"http:\/\/grafica3dblog.it\/immagini\/mare-cloud.jpg\" alt=\"\" width=\"475\" height=\"121\" \/><\/p>\n<p>It appears with large areas of black and white, within which there are smaller variations of the same. Do not you think her behavior very similar to the sea? <strong>So use this texture in &#8220;displacement&#8221;\u00c2\u00a0channel <\/strong>of the sea material and it&#8217;s done. (The value of the displacement regulates the height of the waves)<\/p>\n<p>About &#8220;sea&#8221; material: It&#8217;s nothing special! Dark green (RGB = 32,61,64) with fresnel reflections: when the angle increases, increases the reflections. I putted the sun inclined to emphasize the effect.<\/p>\n<p><img decoding=\"async\" loading=\"lazy\" title=\"premium-area-test2\" src=\"https:\/\/www.cg-blog.com\/images\/premium-area-test.jpg\" alt=\"\" width=\"600\" height=\"396\" \/><\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Simulating the sea sometimes requires lot of time and tests.
