I decided to share the CTM add-on to everyone.
This brings back the connected glass optifine feature to Vanillaccurate and in the future other connected blocks as well (quartz, bookshelves, …)
A word of caution though, with 1.16 I had trouble loading the 512x Vanillaccurate pack with a 512x CTM glass add-on on top of it, even though I have 32GB RAM.
With 1.14 I managed to run it much more easily but it was kinda slow.
My advice would be to use a lower-res CTM pack if the higher-res one crashes. This should mostly work without issues (except possiblty in reflections with PTGI).
Check this article to get more hints on how to load high-res packs with 1.16.
Note is pack is cross-compatible between LabPBR and OldPBR versions, so you can use this add-on on top of any PBR format Vanillaccurate.
