LuxCoreRender Forums

For Me this guy is simply the best architectural render artist i know:
It is also clear that corona render make a big difference in quality there also.
Just wonder how this guy render will turn out with Luxcore. could be an interesting experiment.

it's mostly wider internal rendering color space and either custom LUT or specific tonemapping.
I compared both few times already and LuxCore comes close but can't really match it unless you take rendered HDRI out of Blender or otherwise spend significant time on tonemaping. With latest Corona's version gap just widened further.

Yeah that look like a good theory. I've seen great artists failed to reproduce thoses natural mood from corona with another engine so many time.
I'm sure if you give the same scene in Vray or Octane or indigo it will lose the extra added realism. This soft indirect light gradually fading you can almost feel the air in the room
I had something like this once with Mitsuba 8 years ago but ...
It is something i want to investigate.

De facto, it's not a theory, it's practice.
Here's, in my taste even better work... [click on image/link]

Do you mean that if we render in LUXCORE and export the resulted 32bits EXR to corona frame buffer we can prove that the difference come from there ?
Btw isn't OCIO mean to solve this wider colorspace issue ? viewtopic.php?f=5&t=3446&hilit=ocio

I hope, but don't think so, since LuxCore still carries its inner limits. Same as VRay still falls short while Arnold is a beast on it's own (yet both have OCIO support). From what I understand Luxrender was able, but then LuxCore was "optimized" and it since does its magic in "narrow" color space (RGB). But as this i's quite broad & specialized subject which I'm still only scratching ... It would be greatly appreceated, if Dade would explain in short & clear these inner workings of LuXcore.

ie. Like it's done here, where one of main dev. is quoted @ Corona ACES request thread.

But otherwise there are also other things that have put Corona on top of ArchViz engines. Especially the latest, version 7 release. Altho few of "new features" were already present in Lux- way back.

But corona is still RGB like Luxcore. So I don't think it is spectral vs RGB.
What I know is that Always output EXR to another software like darktable
or rawtherapee is much better than setting stuff with Blender Filmic.

Also so pretty advanced guy in Colour seems to not be that impress by ACES

Thing is, that simulation not only occupies wide color space but it also" understands and works with it" even, if result is later narrowed down. How it narrows it down is another question, a tone mapping one.

BTW, ACES basically helps lessen errors, helps achieve better precision, in controling color grading recordings taken w/ different cameras/standards. Easier to get unified look when one take is shot with Arri, another with Red, other with Sony or Canon or DJI...

Amazing images. I’d love to be able to create to that standard.
