I was aiming to update the OP last weekend, but things happened. Anyways, the most recent version of ReShade still doesn't work so we're still stuck with v3.0.3 (
https://reshade.me/downloads/ReShade_Setup_3.0.3.exe, note multiplayer will have the depth buffer blocked without building or downloading a patched version), and can't be bothered to try to find out what changed to break it for Blockland. I'm still waiting for someone to port the GPU Gems Godrays from 2.0. Lastly, if you can't find MXAO 3.1.0 (the latest release, note that he teased a raymarch SSAO before):
https://pastebin.com/Gn3EUMyfI might tweak around more with shaders and adding dynamic options to change the shadow offset/fudge with the light direction's z axis, and you might have seen the topic about shadows getting softer with distance, but it's far from perfect, but it's in a demoable state open for any revisions/improvements.
I dug up some circa April 2014 (some of my earliest) soft shadow shader screenshots I made using the max shader screenshot mod since I wasn't using a high end GPU to run shaders constantly (even now I still often play with them off). What sorta bothers me is that the soft shader used in Hata's Shader Toggle was changed from the original settings it was released with.
