Export of denoised light group layers

Hi

I'm working on BlendLuxCore.
Is there a way to save result images for each light group individually denoised?

In a perfect world this will be possible while rendering is still active, or the light group adjustment keeps alive after stopping the render.

Thank you.

Re: Handling of relative refractive indices

Hi, I'm not talking about small tiny surfaces. It's a plastic part that is made in 2 shot process. One shot is a clear polycarbonate and the second shot is a black acrylic... This part is later on illuminated (through the clear element) by few LED In real life the intermediate face of those two volu...

Re: Handling of relative refractive indices

Hi, It does for glass. This means that one could have an light guide effect of a glass tube surrounded by some black acrylic cladding? At least for a very narrow (almost parallel) beam pattern it should work... I'll investigate that a bit... Back to the main topic. Do you think this fresnel behaviou...

Re: Handling of relative refractive indices

Hi, Thanks for answering... Well, the situation described by epilectrolytics is what I meant. So yes, the result is always the same no matter of the volume IOR you are inside. If this is really the case the result is wrong... From my opinion you have to calculate the relative IOR before calculating ...

Re: Support for more IES variations

Hi,

It seems that no one wants to answer.
I'm quite sure that with a little work lux core could have the best IES integration that exists in rendering market. Even professional products struggle with the usage of the different orientations in IES.

Handling of relative refractive indices

Hi, This is my situation... I have a very glossy refractive surface. Its like a piano black finish. This face uses the "use IOR" option with an IOR of 1.5. It's diffuse color is set to perfect black. It's roughness is 0.001. The exterior volume of this face is a clear acrylic volume, also using an I...

Support for more IES variations

Hi, I'm trying to set up a virtual automotive lighting head light testing environment. The idea is to have a road scene that shows the quality of low beam/driving beam/etc. light distribution. I'm in early beginning of this project, but I'm already struggling with the usage of IES lights. My main pr...

Re: Understanding .ies parameters, efficacy

Hi, Totally agree with marcatore proposal. For technical use it would be useful to define all possible light sources with suitable values and units. From my point this means. Area lights may use [lm] Point light sources also in [lm] Laser sources may defined in [W] but make users aware that this is ...

Re: Understanding .ies parameters, efficacy

Hi, This seems to be a good chance to be the smartass. The power in W that is stored in an IES file is the electrical power consumption. It doesn't really say anything about the real brightness. The luminous flux in lm is the measure that gives the amount of light that is emitted by the luminarie. S...

Re: anisotropic metal UV problem

Hi,
It's might be light falling at different angle.
Moved lamp a bit to the right:
stupid me, it was really simply the position of the lightsource and the orientation of the disc.
Thanks for helping me. I've additionally added a normal texture to emphasis the polishing direction.
