I think would be very usefull and lightweight instead of using layer nodes, mostly for procedural stuff like darkening/tint areas with cuvature/dirt, or lookdev characters with dedicated maps for make up, sweat, skintones.
If I have my cameras hidden in 3dsmax, they don't show up in Vantage. This has become such a pain as sometimes I forget to unhide them when exporting. Please allow a checkbox to 'export hidden cameras' in the Max plugin.
