I am happy I recorded these sequences; all I had to do is search odinzu ray tracing rtx to get back up and running with fresh install of MC on Ubuntu; most importantly, I have shared them for free with the public to create extra awesome sauce on MC. I hope you enjoy this setup as much as I have! You may reach me here or on Discord at:
Followed the instructions for 1.16.3 and these worked flawlessly; the only thing to consider is SEUS Renewed; I didn't create specific instructions on how to get this up and running..it is basicllly the same as Opti Fine HD, but you load the shader in the video settings. If it is already loaded in a previous version, it will still be there in the Home > .minecraft > mods directory and is compatible with OptiFineHD 1.16.3
