Re: Full invisible area light

It is already possible to make a light source invisible to specular materials, there is a dedicated flag for visibility on diffuse, glossy and/or specular materials :?: Oh..sorry. You're right. I've tried and it works. Good. And MIS is still there...at least the sampling seems the same of the "norm...

Re: Full invisible area light

Just a question. As Dade was able (unintentionally) to make the area invisible for specular material and now it fixed making area visible ... is it undoable to "split the code" -> if Visible to spec mat = true run the last fixed code, else run the unfixed code? Am I too ignorant how the things are w...

Re: Full invisible area light

I have now fixed the behavior with specular materials too ... Noooo.... :) It was better like before..in my opinion. More useful... For example I have a scene (a simple ShopInShop , the last one I've sent many weeks ago) where I used some big area light to faking the lighting of the mall. In this s...

Re: Full invisible area light

I can clearly understand your POV, Dade, but this kind of features are more than welcome as we're always faking when we do rendering. I mean that, except scientific purposes, some degree of faking is necessary to cut down working time and try to have as much feedback from the rendering in the same a...

Re: Full invisible area light

Well..that it's more "correct" than before where the reflection was darker.
As soon as I can I'll test also the direct light. Or do you already test it? It's now the same?

Re: Full invisible area light

I've test the invisible light with direct light. It seems that it emit less light.
I've attached a PSD with the 2 images that show the lighting difference.

Re: Full invisible area light

Is it correct that the reflection of the "invisible" light is weaker than the visible one?

I'm doing some tests...it seems that also the direct light is weaker.
I'll post some images.

Full invisible area light

HI, I've read some messages on LuxCore Discord server to get the area lights invisible in terms of direct visibility and in terms of shadows. Tipical situation is an area light near a ceiling. I've tried to setup the light like suggested but it seems that some occlusion still existing and it reveals...

Re: Battle of chess

with a bit of motion blur you could add more dynamic to the image.
