I made some fixes to the current Vanillaccurate MCPE/OSBES pack. You can re-download it from the same location as before (see original post about the first OSBES release).
The fixes are mostly related to transparency, lots of blocks were missing proper cutouts because my script was somehow wonky. I fixed that so now all cutout blocks should appear correctly (flowers, iron bars, doors/trapdoors, …)
I also re-added some missing nether-related blocks from the 1.16 update. Now crimson/warped stems, stripped stems, doors, trapdoors, planks) are included.
Here are some more screenshots with various blocks. There might still be some blocks missing and/or incomplete but those are very few (maybe some sea plants but that’s about the extent of it).
