Well I’d start getting used to it because the industry has been wanting to transition over since around 3000BC. People just had to work with what was available. Normal maps and other things like POM have just been crutches to fit within the hardware constraints of the time. Nanite is a massive game changer. Not saying every model should just be slopped into a game straight out of Zbrush@40mil tris, without any reduction, but I’m sure you get what I mean.
Going with a more geometry based workflow massively increases the velocity of a developmental pipeline.
