    Yes, that&#39;s what Jordan suggested. :)<br>
    This makes sense and also gives better results.<br>
    <br>
    I hope we will get a better solution though, a good merging system
    would be awesome. :) <br>

          That seems to give better results, right. Still not sure about
          this.<br>

              &gt;&gt; Hi Brecht,<br>
              &gt;&gt; I am testing the Seed function atm in the
              Integrator panel.<br>
              &gt;&gt;<br>
              &gt;&gt; Am I right that images, rendered with different
              seeds can be merged<br>
              &gt;&gt; together?<br>
              &gt;&gt; So for example:<br>
              &gt;&gt; Image_1 has Seed 1 and 1000 Samples<br>
              &gt;&gt; Image_2 has Seed 5 and 2000 Samples<br>
              &gt;&gt;<br>
              &gt;&gt; Do I have 3000 Samples after merging them
              together?<br>
              &gt;&gt; I did that in the compositor with the Mix node,
              factor 0.5 and I used<br>
              &gt;&gt; OpenEXR renders for it.<br>

          If the second image was in the second input, shouldn&#39;t you set
          the Factor to 0.66? :)<br>

              &gt;&gt; The combined result was better than the single
              images, I have the<br>
              &gt;&gt; impression (more noise free).<br>
              &gt;&gt;<br>
              &gt;&gt; Then I rendered another image with 600 samples,
              and combined it to the<br>
              &gt;&gt; already combined result. Now I have the
              impression though that the noise<br>
              &gt;&gt; became more again, rather than less.<br>
