<spanclass="anchor"id="line-1"></span><pclass="line874">This is a step by step guide to creating a simple fire effect. <spanclass="anchor"id="line-2"></span><spanclass="anchor"id="line-3"></span><pclass="line862">Remember that once you have added a segment to an effect you can use binds with <strong>editfx_play</strong> and <strong>editfx_playlooping</strong> to test the effect. This document assumes that after adding one segment you start playing the effect looping on a ground surface in a test map. As the effect is changed in the editor, the looping effect in the world will update. <spanclass="anchor"id="line-4"></span><spanclass="anchor"id="line-5"></span><pclass="line867"><hr/><pclass="line874"><spanclass="anchor"id="line-6"></span><spanclass="anchor"id="line-7"></span><oltype="1"><li><pclass="line862">Open the <ahref="./FXEditor">FXEditor</a> with the <strong>+editfx</strong> console command. <spanclass="anchor"id="line-8"></span><spanclass="anchor"id="line-9"></span></li><liclass="gap"><pclass="line862">Click <strong>File>New</strong> or hit <strong>CTRL + N</strong>. <spanclass="anchor"id="line-10"></span><spanclass="anchor"id="line-11"></span></li><liclass="gap"><pclass="line862">Right click inside the Segment window and click <strong>Insert>Sprite</strong>. <spanclass="anchor"id="line-12"></span><spanclass="anchor"id="line-13"></span></li><liclass="gap"><pclass="line862">Click the <ahref="./FXEditor_Tab_-_Sprite">Sprite Tab</a> and in the <ahref="./ArtReference_Q4Shaders">material field</a> (where it says '_material') enter a path to your fire image shader.
