There are many ways to do that, there are many photoshop plugins and we also learnt how to do simply add flares in the <a href=\"https:\/\/www.cg-blog.com\/index.php\/2012\/07\/01\/final-render-ambient.htm\"> Lesson#24<\/a>. A flare is basically composed by two components: <strong>Bloom<\/strong> (a bright halo) and <strong>Glare<\/strong> (the typical star effect). In this lesson I&#8217;ll show you how to add and control this effect directly in V-Ray using VRayLensEffect.<\/p>\n<p>Watch the next video to learn more about complex materials in V-Ray:<\/p>\n<p><iframe loading=\"lazy\" src=\"http:\/\/player.vimeo.com\/video\/62687533\" width=\"900\" height=\"506\" frameborder=\"0\" webkitAllowFullScreen mozallowfullscreen allowFullScreen><\/iframe><\/p>\n<p><strong><img decoding=\"async\" src=\"https:\/\/www.cg-blog.com\/wp-content\/uploads\/2013\/02\/main-concepts.gif\" alt=\"\" \/>CONCEPTS<\/strong>:<\/p>\n<ul>\n<li>Add VRayLensEffect before the render starts;<\/li>\n<li>Use &#8220;update&#8221; button to check it;<\/li>\n<li>Use &#8220;glare type render camera&#8221; to control Glare;<\/li>\n<li>Higher <em>f<\/em> values produces bigger stars;<\/li>\n<li>Enable &#8220;diffraction&#8221; for a more realistic simulation;<\/li>\n<li>Optimize GI using low values for Low-key images;<\/li>\n<li>&#8220;Use Light Cache for Glossy Rays&#8221; reduce a little bit the render time;<\/li>\n<li>The VRayWireColor render elements is useful to create fast masks;<\/li>\n<li>Use a black layer in &#8220;HardMix&#8221; to check overexposures;<\/li>\n<li>Add Reflections layer in &#8220;Screen&#8221;;<\/li>\n<li>Unsharp Mask 80px \/ 30% &gt; improve the general contrast;<\/li>\n<li>Unsharp Mask 1px \/ 80% &gt; improve the definition.<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<p><strong>V-RAY LIGHT: DISABLE REFLECTIONS TO SAVE TIME.<br \/>\n<\/strong>As you know 5SRW promotes an absolute realistic approach: recreate the 3d scene as the reality is. That means we never do strange things like disabling reflections for a light since this is not real.<\/p>\n<p>But is there cases in which to take advantage of not-real settings? Yes, to save render time: <strong>less reality often saves time<\/strong>. Do it espacially if this loss of realism is marginal.<\/p>\n<p>In this scene all these V-Ray Light Sphere have an impact in the render time because of glossy reflections in the wall behind.<\/p>\n<p>Disable <strong>Affect Reflections<\/strong> abd the image will be rendered much more clean and faster:<\/p>\n<p><img decoding=\"async\" loading=\"lazy\" class=\"alignnone size-full wp-image-3290\" title=\"slide-affectrefl\" src=\"https:\/\/www.cg-blog.com\/wp-content\/uploads\/2013\/03\/slide-affectrefl.jpg\" alt=\"\" width=\"600\" height=\"241\" \/><\/p>\n<p><strong>Future V-Ray Feature:<\/strong><br \/>\nAs you can see we unfortunatley lost the nice reflections on the glass! At Chaos Group developers are working to add this feature: &#8220;disable reflections for specific objects&#8221;. We just need to wait a little \ud83d\ude09<\/p>\n<p><strong>Note<\/strong>: Actually the same thing is with antialiasing. We could use &#8220;Adaptive subdivision&#8221; for final renders: less time&#8230; but less definition. Since we produce photorealistic-high-impact-images, as standard we use Adaptive DMC 1\/40 as antialiasing for the final render (step4).<\/p>\n<p><strong><strong><img decoding=\"async\" src=\"https:\/\/www.cg-blog.com\/wp-content\/uploads\/2013\/02\/exe.png\" alt=\"\" \/><\/strong> EXERCISE<\/strong>:<\/p>\n<p>In the link below download the final rener and render elements to produce the prost production as illustrated in the videos, especially keep attention on double usage of &#8220;UnSharp mask&#8221; and all different bleding modes for different render elements:<\/p>\n<ul>\n<li><a href=\"http:\/\/www.learnvray.com\/files\/dark\/darkl-s5-start.zip\">Render and Render Elements<\/a> (4 images)<\/li>\n<\/ul>\n<p>Links to verify the final settings and post production:<\/p>\n<ul>\n<li><a href=\"http:\/\/www.learnvray.com\/files\/dark\/darkl-s4-final.zip\">Dark Living &#8211; Ready for FINAL RENDER<\/a> (max file)<\/li>\n<li><a href=\"http:\/\/www.learnvray.com\/files\/dark\/darkl-s5-final.zip\">Final Post Production<\/a> (Psd file)<\/li>\n<\/ul>\n<p>[\/private]<\/p>\n","protected":false},"excerpt":{"rendered":"<p><strong>LESSON #40<\/strong>: In this lesson I&#8217;ll show you how to create bloom and glare effects with Lens, how to save time with lower GI and a solid workflow for Post Production with render elements.<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"om_disable_all_campaigns":false},"categories":[50,51],"tags":[],"aioseo_notices":[],"_links":{"self":[{"href":"https:\/\/www.cg-blog.com\/index.php\/wp-json\/wp\/v2\/posts\/2337"}],"collection":[{"href":"https:\/\/www.cg-blog.com\/index.php\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.cg-blog.com\/index.php\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.cg-blog.com\/index.php\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.cg-blog.com\/index.php\/wp-json\/wp\/v2\/comments?post=2337"}],"version-history":[{"count":0,"href":"https:\/\/www.cg-blog.com\/index.php\/wp-json\/wp\/v2\/posts\/2337\/revisions"}],"wp:attachment":[{"href":"https:\/\/www.cg-blog.com\/index.php\/wp-json\/wp\/v2\/media?parent=2337"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.cg-blog.com\/index.php\/wp-json\/wp\/v2\/categories?post=2337"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.cg-blog.com\/index.php\/wp-json\/wp\/v2\/tags?post=2337"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
