I have pushed the BlendLuxCore implementation on the "2.79_maintenance" branch:

Simon do you think that with this Disney BRDF shader we still need a shader translater from Luxcore to Cycles and vis versa ?

Some translation will still be needed, yes.
But what I want to try is to use Cycles nodes directly, without the need to convert them to a LuxCore node tree.
However, I can't show messages in Cycles nodes (at least I think I can't) so I can't tell users in the UI which nodes are supported and which are not. For this reason it's very good to have the disney material as a baseline of interchange.

What about having a "virtual" node in LuxCore materials where you can reference a Cycles material
This kind of nodes can be also created automatically by a script to translate s Cycles to LuxCore scene.
The virtual node could also show all kind of diagnostic messages if the Cycles material can not be translated or can only be partially translated.

That's a cool idea!

Dade fix broken network render since I already converted all of my 100 materials in my god scene to the glossy material aka the disney shader

...aaand it works!
Thanks Stefan, David and Simon!
First try with PBR wood and tile materials
(from
here):
^ glossy
v Disney
I was not able to tweak the parameters so that both look the same, roughness works totally different between the two.
Disney renders slower (450k/s vs 530k/s).

I have no Idea, but you can adjust the brightness (of the reflections) with roughness and specular values.
