Principled v2: Lukas published a branch with an early (incomplete) version, there is a feedback topic with active discussion.
If I got it right, the new v2 Principled is incompatibel to the v1?
I think backwards compability is pretty important, espeically for all these people who started to create an material Asset Library or all the third party shader and assets packs. Would be not great if all of those would need an update.
Are there any plans for a 100% backwarts compability?
Maybe having a dropdown, with v1 and v2?
