is there a fast and easy way to convert v2020 Materials into v2026? It is from a pack we bought and now most of them are useless. Some seem to be wrongly wired (depends on Octane version), some are simply crashing Cinema/Octane - and this fast and often
I am working in R20 for the conversion to get the v2020 to run so I don't have to switch it in R21 back an forth.
And is there a way to convert Layered Materials automatically? I tried the manual way with exchanging the layer and using a submaterial instead. Wich looks different sometimes, and this way may take really long.
So if there's a way ...
