It Still archviz as i think there is still alot to explore in this Field.
The scene at first sight look challenging for any renderer Especially
The Heaven like ceilling (transluscent + Heavy Indirect light).
I decide to make one Bidir+metro render as well as GPU path.
Final 2K Ouput GPU GI Cached 1Hr render each
Bidir left over night for 6Hrs : 24 + 24 Deph
6mn GPU denoised
Would be nice as Luxmark complexe Scene Sample
