scaling sun is visible in reflection, this looks terrible in cases where you can easily see the reflected sun/distant light.
indeally, as the sun would get bigger it would also get blurrier in reflection (as if behind clouds) so that we don't see a weird huge sharp ball when we need soft shadows from sun.
The other option would be keep sun small in reflection while large as a source of lighting.
Or best have control over how big the sun is in refl. and/or how sharp reflection it does...
Is this doable?

Re: sun/distant light reflection
Changing the blurriness of the reflection is something that is controlled by material roughness and should never be controlled on the light.lacilaci wrote: Mon Jan 06, 2020 2:49 pm indeally, as the sun would get bigger it would also get blurrier in reflection (as if behind clouds) so that we don't see a weird huge sharp ball when we need soft shadows from sun.
One thing that could help though is just giving a small edge falloff on that sun disk so it doesn't look too sharp.
I would rather get a way to disable sun specular to rely on an HDRI reflection instead, although I don't think it's possible with bidir. Not being able to control light path visibilities is a big drawback in LuxCore in my opinion, but that's the way it is.

Oh yes, that's what I'm asking for. Poor wording.chafouin wrote: Tue Jan 07, 2020 4:03 am

No, I definitely wan't sun reflecion in most cases...I would rather get a way to disable sun specular to rely on an HDRI reflection instead, although I don't think it's possible with bidir.
Yes, I made this request long time ago: https://github.com/LuxCoreRender/LuxCore/issues/148Not being able to control light path visibilities is a big drawback in LuxCore in my opinion, but that's the way it is.
