I think, jumping to the pole position in the AEC is a "dream" for archicad, that can't be achieved at least in the 5 coming years, Autodesk is dominating architecture, structure, MEP and now GIS, and graphisoft, or nemestcheck, alone , cant fight this huge wave.
in 2014, render legion created corona renderer, a rendering engine for 3ds max, it was a very basic rendering engine, with some good features, not competitve to Vray, but it do the job,
in 2016, corona render V1 was released, and it was a BOMB in the Archviz market, a LOT of Vray users moved to corona, for one simple reason : no render settings , all works great by default, Vray need too much of settings to deliver a good render,
November 2017, Render legion joined chaos group ( vray ) and they announced a cooperation between the two competitor companies, CG artists thought it was the end of corona, and Vray will kill it's competitor,
now we are in 2021, and since 2017, every release of corona render brings new functionnalities, new technology, and compatibility with Vray, with a stronger development road, and an open roadmap,
if this would be reproduced with Graphisoft and Autodesk, for cooperation and developpment purposes, that would be a Huge gain for the community, Graphisoft remain under nemestcheck, but cooperate with it's rival, revit,
looks impossible, yes, but why not !
