What you think of Detail Enhacement ?

I find it quite useful with GI caustics and VRay Light Mtl, as you don’t need high Irrmap settings for the QMC quality :slight_smile:

Here’s quick comparesion.

Irrmap set to Low, DE=on
(DE->Detail Enhancement)

Irrmap=Low
DE=off

Irrmap=High
DE=off

QMC (first and secondary)
12 subdivs + 3 bounces

:smile:

Are there times with these?

Click on thumbnails…

Thanks. :sweat_smile:

I don’t get it. The top image with IRR/DE is 1m 21sec and the QMC is 1m 14sec.

How is the DE faster?

Yes indeed :smile: How :slight_smile:
Too many pictures so I confused a little . . .

At the default settings it seems pretty slow in my tests, haven’t tested beyond turning it on and canceling the renders though. :slight_smile:

I imagine it can be optimized a bit

For such simple scenes, there isn’t much point in using the detail enhancement, as QMC GI does the job very well in these cases.

It is really useful for more complicated scenes (like interior renderings) where you want the small details from the QMC GI, but don’t have the time for it.

From my experience, good settings when using the detail enhancement are Medium preset for the irradiance map but with Interpolation samples set to 50, and more or less default settings for the detail enhancement.
