I have been working on updating this connected texture patch to 1.16, and I have taken the time to significantly expand what it does. Look at the what's included section for details.
What is important is that you DO NOT use this alongside the normal CTM patch you can download on the main page. You can read why below.

Why Not To Use Normal CTM Patch Alongside This
The main connected textures patch includes no artwork, only the metadata files required to make them work. Most of the files in the normal patch use the matchBlocks method, while this patch generally uses matchTiles. The reason for this is that with matchBlocks, stairs and slabs do not work with the connected textures unless they are specifically defined.
This patch also adds transitions for other blocks, which required rewrites of the vanilla transition metadata to allow the vanilla transitions to cover certain modded blocks. These new transitions sometimes won't load if the vanilla lines are present. Worst of all, z-fighting can occur when two different OptiFine files are trying to do the same thing at once, so in order to avoid running into that issue, we recommend that you do not use the vanilla CTM patch with this in tandem.
What's Included Right Now
All connected texture functions of the vanilla CTM patch are included. They have been altered to support additional block variants.
Connected black and white black sandstone for Biomes O' Plenty
Connected certus quartz for Applied Energistics 2
Connected jungle log top
Connected wood textures for vanilla and Biomes O' Plenty
Extended wood textures to support slabs and stairs
Override files to prevent the main pack's wood customization from causing
this issue
Override wood textures to make connected textures fit in
Random colors for cake top
Random melon sides
Random sand and snow for vanilla and Biomes O' Plenty
Transitions for Biomes O' Plenty sand variants (clay < black sand < red sand < sand < white sand < gravel < grass < snow)
What's on the To-Do List
Extending this to other modded wood variants is planned once other mods are updated (Forestry variants are already finished for 1.12.2)
Issues
Please let me know if there are any issues encountered. I have been moving quite quickly when working on this, so there's bound to be something that I forgot to fix.
