make rectangle light longer than 3 meter

:confused: i think you guys must make rectangle light more longer

I’m curious: what use would you put it to?

Why wouldnt they just extend to match the size of the actual rectangular light… How it currently is is pretty annoying… I end up having to make large light arrays in rhino.

@jessegould Do you mean the light distribution isn’t like expected if the light size is larger than 3m? So far I understand rectangular light based on a kind of point lights, but maybe the RTX technology allow to implement better looking area lights. What do you think @Simon_Weinberger ?

@Micha Light distribution of area lights is different from that of point lights. I don’t have any deep insights into why the limitation exists but I’m pretty sure it is a combination of performance and correctness considerations.

RTX by itself does not allow anything that wasn’t possible before, it is just a performance improvement that allows us to do more/better calculations without affecting user experience.

At one of the RTX videos I heard something about better and noise free area light shadows and so I hoped, this could be implement to Enscape too.

The workaround for huge area lights is to use emissive objects. This is also very similar to what you have seen in GDC videos @Micha .

If I could make emitters invisible, than I could use emitters. My clients like to get large interior spaces rendered and without visible light source I need to bring light to specific areas. It could be great to switch area lights in a hidden emitters mode, maybe per naming.

Thanks, forwarding this +1 to the feature request. :slight_smile:

It would also be great to get some feedback as to whether this is even a remote possibility (invisible emitters) From memory when this has been requested in the past it seemed as though this was not going to happen.

Thanks!
