<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>hairs direct highlights and get rid of bright pixels from
indirect.</div>
<div><br>
</div>
<div>One of the most fireflies-prone setup is tiny radius
spot-point lights lighting sharp glossy.</div>
<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
tone range.</div>
