Kappa Shader v4.1

Its finally time for the big refinement pass of Kappa 4.0, which should improve upon many of the weaker points as well as providing a much more consistent and appealing look.

In order to achieve that I’ve been spending a lot of time on tweaking all the internal knobs and replacing bits and pieces here and there to iron out many of the things that I still deemed suboptimal in 4.0’s release. This includes the rather harsh and slightly cold look at daytime, the lackluster filtering of the SSPT, the exposure behaviour in dark scenes with bright spots as well as a variety of other minor things. Perfection is lots of little things done well, and this release should get one step closer to that thanks to all the little things that have been tweaked and improved upon. As its quite a list of changes I’ll let you scoop through the changelog below now and then take a look at it yourself when testing the pack. I hope many of you will like the changes :p

Only 1.16.4+ is supported at this moment since the new OptiFine features have not yet been backported! Also needs OptiFine G7 or newer.
