World Shader Settings<\/h2>\n

The World Shader<\/strong> sets an environment’s light ambiance and background appearance. Since Sturdy<\/em><\/strong> makes color expression dependent on light position and intensity<\/a>, the World Shader<\/strong> will influence the shader’s effects a lot — maybe too much.<\/p>\n

It may actually be necessary to tone down the influence of the World Shader<\/strong>, so you you may paint color with lights<\/a> that you can directly control (say, the Sun Light<\/strong> or a couple of Area Lights<\/strong>).<\/p>\n

As a reference you may use, append or copy the Sturdy World<\/strong> world shader present on the provided Blender files. If you open it on the Shader Editor<\/strong>, you’ll find a simple node tree with two color inputs.<\/p>\n

\"\"<\/a><\/p>\n

\u25bc Environment Lighting<\/strong>
\nYou may pick a color or plug anything you want here — say, an HDRI image on an Environment Texture<\/strong> node. Just but be sure to use a very low value on the Strength<\/strong> slider, for instance: 0.2. Most of the time it will be safe to leave Strength<\/strong> at 0 and control the environment lighting with standard lights on the viewport.<\/p>\n

\u25bc Background Color<\/strong>
\nThis will determine the background appearance.
\nPick a color if you want a flat background, or plug something else on the color input — say, a custom HDRI image on an Environment Texture<\/strong> node.<\/p>\n

Lights<\/h2>\n

Be sure to add lights to your scene: you’ll be painting with light!<\/a><\/p>\n

If you want to use a Sun Light<\/strong>, use a Strength<\/strong> of \u03c0<\/strong> for maximal value mapping. Just write pi<\/em> on the Strength<\/strong> field of the Sun Light<\/strong> you added and click enter. And then be sure to rotate the sun on all axes until you find the perfect view.<\/p>\n

Adjust the color expression of the shader with other lights, if you will. Check the provided Blender files for simple lighting setups you may adapt or use as a reference.<\/p>\n","protected":false},"featured_media":0,"parent":54,"menu_order":6,"template":"","doc_tag":[],"class_list":["post-189","docs","type-docs","status-publish","hentry"],"comment_count":0,"_links":{"self":[{"href":"https:\/\/paulobrabo.com\/brabarous\/wp-json\/wp\/v2\/docs\/189","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/paulobrabo.com\/brabarous\/wp-json\/wp\/v2\/docs"}],"about":[{"href":"https:\/\/paulobrabo.com\/brabarous\/wp-json\/wp\/v2\/types\/docs"}],"version-history":[{"count":10,"href":"https:\/\/paulobrabo.com\/brabarous\/wp-json\/wp\/v2\/docs\/189\/revisions"}],"predecessor-version":[{"id":394,"href":"https:\/\/paulobrabo.com\/brabarous\/wp-json\/wp\/v2\/docs\/189\/revisions\/394"}],"up":[{"embeddable":true,"href":"https:\/\/paulobrabo.com\/brabarous\/wp-json\/wp\/v2\/docs\/54"}],"next":[{"title":"Creating your own Sturdy materials","link":"https:\/\/paulobrabo.com\/brabarous\/docs\/sturdy\/usage\/creating-your-own-materials\/","href":"https:\/\/paulobrabo.com\/brabarous\/wp-json\/wp\/v2\/docs\/284"}],"prev":[{"title":"Render Settings","link":"https:\/\/paulobrabo.com\/brabarous\/docs\/sturdy\/usage\/render-settings\/","href":"https:\/\/paulobrabo.com\/brabarous\/wp-json\/wp\/v2\/docs\/180"}],"wp:attachment":[{"href":"https:\/\/paulobrabo.com\/brabarous\/wp-json\/wp\/v2\/media?parent=189"}],"wp:term":[{"taxonomy":"doc_tag","embeddable":true,"href":"https:\/\/paulobrabo.com\/brabarous\/wp-json\/wp\/v2\/doc_tag?post=189"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
