I'm in a server with version 1.16.5 with some friends. I made and shared the modpack so all we have the same. But I'm the only one who can't see that blocks. I tried to solve it by reinstalling minecraft and removing all texture packs.

can you tell the mod list please? have you tried to toggling flywheel renderer on and off?

I have the same problem, but on 0.3.2d

the mods are: dungeons content, tinkers construct, create, quark, chisel, biomes of plenty, securitycraft, pirates and looters, jei, xaeros minimap, relics, mantle, flywheel, simple ores, travellers backpack, morevillagers, curios forge, corpse, ctm, hwyla, simplecorelib, autoreglib and appleskin. But I don't think thats the problem because my friends have exact the same modpack and they don't have any problem. Respect to the second think, how can I do it?

thanks, I solved by writting /create experimentalRendering off

i don't remember the command tbh, but check /flywheel or /create
