It is impossible to use a Resourcepack that requires Fabulous Graphics to be turned on, as this cannot be done.

It is not a GUI limited problem, as I have tried changing the graphicsMode value to 2 in options.txt, but that either results into it being set back to 0/1 (fast/fancy) or into crashes.

I am aware not everybody uses Fabulous Graphics, but in my opinion, making them work with Vulkan would be an efficient way to circumvent the lack of shaders support.

Good job with this mod by the way! It is amazing! :)

It's disabled in GUI because it doesn't work.
