Using archglass is a terrible idea, it never looks good (aside flat panels like in a windows in distance). It would be much better to have an option for object to let gi go through.

In this one it isn't archglass but true glass at 1.33 IOR. but it produce so much noise :oops: . so denoiser and clamping just kill it even at loonger render time.

About option to let light pass throught if that possible how it look like (visualy). i suppose Corona have something like that. It would be nice if it help with noise and without creating very huge Bias. if the introduced bias is hardly noticeable like PGI vs full path i think it is something to consider.

Laci if you have a picture of this feature in any renderer i want to see please. ;)

Here you can control everything about GI behaviour for every object in the scene

Edit just trust luxcore a bit more. using Glass 2 aka volume glass give far better result with less noise :D

Cycles has these options per object!

vray, corona, cycles, even maxwell! has options like that to boost performance with complex objects like glass panes etc.

With cycles I disable diffuse, glossy and shadow options on object and I get glass that on camera looks just as real glass but it interacts with scene the same as archglass in luxcore. And you can do this trick with curtains and similar objects. It's a common practice in archviz with vray and corona and works flawlessly with cycles too.

Now I know, Dade is busy now with a lot of other stuff, but I hope at 2.3 or so, this will be implemented for luxcore too.
