BlockquoteIt’s useful to know that 3.0 could mess up some things about the files / content. I’ll need to address that if it persists…
For fun, I did a side by side test of Abe in 2.93 and the 12 Nov 3.0 Beta. The lighting differs, and possibly the hair shader looks different (though it may be the lighting), but otherwise, there don’t seem to be any catastrophic failures.
And I pre-ordered as soon as I saw your OP. I simply must learn the shaders.
