I've encountered an issue where the sides of blocks that are not in view aren't rendered with specific texture packs. The ones I saw this with were Reimagined and Excalibur.

I'm using Fabric 0.14.21 for 1.19.4

Mods:
Alternate Current
AmbientSounds 5
AutoSwitch [Fabric]
Chat Heads
CleanCut
ClothConfigAPI (Fabric/Forge)
Collective
CreativeCore
Entity Culling Fabric/Forge
Entity Model Features [CEM] [Fabric & Forge]
Entity Texture Features - [Fabric & Forge]
Fabric API
Fabric Language Kotlin
FerriteCore (Fabric)
Indium
Lithium (Fabric)
Mod Menu
Phosphor (Fabric)
Reese's Sodium Options
Sodium
Sodium Extra
Sound Physics Remastered
Xaero's Minimap
Xaero's World Map
Zoomify

Looks like you don't have any mod that adds support for the Optifine features these packs use. Try using Continuity?

this seems to be in my logs when blocks dont render the sides

here is how the game looks like

im also getting the same issue

and this issue too

@GentlemanMC You have a different issue, see #199.

@MarshmallowPeep Could you send a log file from when this issue occurs?

Since the issue occurred, I loaded a backup of the modpack and that seemed to fix it, but I'll try to recreate it again and I'll send the error log then

Closing: old issue with insufficient information to diagnose
