Universal settings slow with Bright highlights

[nils_p]

To my satisfaction I recently started using the Universal settings with the color threshold.

But what I noticed is that with very bright speculars those buckets render very slow. Is there any way to speed this up?

Thx

You could try the "subpixel mapping" and "clamp output" options; you can set the clamp level a bit higher than 1.0 - perhaps 5 or 6, so that some of the HDR information is preserved.

Thx, that seems to work
