      <div dir="ltr">That could be even better and more flexible. IMHO
        this could also help hair rendering with Hair BSDF potentially,
        <div>since it involves reflections, it gives fireflies quite
          easily, thus having this indirect clamping could preserve</div>

        <div>One of the most fireflies-prone setup is tiny radius

        <div>I've made a super simple scene (in the link) showing this,
          using MIS and/or filter glossy doesn't help,</div>
        <div>the only thing helping is clamp but then we loose the whole

            &gt; Yes, I can see that would be useful. We could split up
            the clamp<br>
            &gt; option in direct and indirect parts so you can still
            clamp direct as<br>
            &gt; well but less.<br>

            &gt; &gt; Hi all,<br>
            &gt; &gt; i was wondering if current clamp option is
            affecting every ray (also direct<br>
            &gt; &gt; ones), and maybe it could be made to affect just
            secondary rays to clamp<br>
            &gt; &gt; fireflies from glossy bounces etc, while
            preserving direct<br>
            &gt; &gt; highlights/reflections on shiny objects. Makes
            sense?<br>
