Cool !
That’s a great experiment to make ! Would be interesting to get some numbers to see the performance impact , but that’s some work …
I’ve done it for mixing shaders here : Mixing multiples shaders in Eevee - #4 by sozap
And I generally manage to avoid that, but it give me way more convoluted networks…
I see people mixing shaders a lot in many tutorials but they probably don’t care about optimizing, or maybe they are not aware of the performance cost…
I was a bit wary that you’d get too much complex solutions , but you seems to know what you’re doing very well ! I’m quite curious on the results you’ll get !
I never though about making atlases, that’s a neat trick , thanks !
