To create pleasing compositions using correctly the lights, is necessary to have a solid theoretical knowledge, we note as the 5SRW method have a logical, rules and it allows us to achieve the desired result by applying the same logic in every scene. In this case I&#8217;ll show how to use a VRayLight Dome with a VRaysky and HDRI (High Dinamic Range Image).<\/p>\n<p>The Following images are the end result of this lesson, I will show how balance the lights, getting both lighting.<\/p>\n<p><strong><a href=\"https:\/\/www.cg-blog.com\/wp-content\/uploads\/2013\/01\/sky-hdri.jpg\"><img decoding=\"async\" loading=\"lazy\" class=\"alignnone size-full wp-image-2239\" alt=\"sky-hdri-icon\" src=\"https:\/\/www.cg-blog.com\/wp-content\/uploads\/2013\/01\/sky-hdri-icon.jpg\" width=\"600\" height=\"335\" srcset=\"https:\/\/www.cg-blog.com\/wp-content\/uploads\/2013\/01\/sky-hdri-icon.jpg 600w, https:\/\/www.cg-blog.com\/wp-content\/uploads\/2013\/01\/sky-hdri-icon-300x167.jpg 300w\" sizes=\"(max-width: 600px) 100vw, 600px\" \/><\/a>\u00c2\u00a0<\/strong><\/p>\n<p>[private Premium|Premium-1year]<\/p>\n<p>In the video below I show you how to do a &#8220;Magic Hour&#8221; render.

In this way we can play with our HDRI until achieve the desired lighting. We will also use VRaylight dome as a way for applying the HDRI<\/p>\n<p><strong>WHAT IS A &#8220;V-RAY LIGHT SUBSTITUTE&#8221;?<\/strong><br \/>\nThis is a simple definition we use in our live workshops. V-Ray Light &#8220;Substitute&#8221; means that we separate <strong>source<\/strong> and <strong>light<\/strong>. For the source we use a VRay Light Material and as light we use an invisible V-Ray Light (with &#8220;affect specular\/reflections&#8221; \u00c2\u00a0disabled). The only purpose is simplify the calculation.
