Windows 11 - updates installed to date,
Intel i512600KF,
32gb,
RTX3060ti - drivers up to date,
Minecraft Bedrock -26.52 .
BetterRTX installed.

I've been testing various RTX texture packs and comparing them with VV or with Ray tracing,
I obviously found Optimum Realism,
I installed the 64x and tried with VV and ray tracing and it looks pretty good I cant deny.

I upgraded to the 256x, once I loaded back into Minecraft I get the error above and Ray tracing is Greyed out in the options,
I downloaded the 128x version, installed and i get the same errors as the 256x.

why wont these two packs run,
what can i change?

I can still run ray tracing on the 64x so I am confident my PC is working, or at least to a point.

Some block sides seem to revert to vanilla, depending on the direction they're facing. I've noticed it so far with dispensers/droppers. Here are some screenshots of the dispenser/dropper facing sideways, up, and down. Only sideways does it show the lion face. I tested this in 26.x as well as 1.21.x, the only mods I'm running are EMF, ETF, Continuity, Fabric API, Iris Shaders, Lithium, Polytone, and Sodium.

I have a problem, on the x64 version i can use raytracing but above its just always gray but idk what to do..

Hi,
​My Patreon subscription ended in less than a month—actually in less than two weeks. I would like to know what caused this issue. Also, I hope you can restore my subscription for the remaining time I paid for and explain why this happened.
​Thank you!

I have this problem in optimum 4.1.0 how can i fix it ? my version is 1.21.1

Hi everyone,
I’m running into an issue with the 256x Bedrock version of Optimum Realism on a high-end PC setup and wanted to check if there's any known workaround.

My Specs & Setup:
CPU: AMD Ryzen 7 9800X3D
GPU: NVIDIA GeForce RTX 5080
RAM: 48 GB DDR5
OS / Game: Windows 11, Minecraft Bedrock Edition (latest version) with BetterRTX patched

The Problem:
I can successfully import and select the 256x resource pack in the main menu / global resources.

However, when loading into a world, the pack fails to load and throws a memory/file size error ("Not enough memory" / resource pack loading failed due to large files).

Because the engine drops the pack during world load, the Raytracing toggle remains greyed out in both world and video settings (since no PBR assets are recognized).

I've tested this with only Optimum Realism installed (no other addons/packs) and have tried clean reinstallations of the pack.
I understand that the Bedrock UWP engine has a strict internal texture buffer cap that uncompressed 256x PBR maps tend to hit during startup, regardless of actual system RAM/VRAM.

Has anyone managed to bypass or raise this UWP memory buffer limitation for 256x packs on Bedrock, or is 128x the hard ceiling imposed by the engine architecture?
Thanks in advance for any insights!

I've tried every way to select ray tracing with the bedrock resource pack activated and can't get it ungreyed out. Anyone else had this issue? I'm using bedrock on my pc to play with my girlfriend on Xbox using our realm world. The swords and tools are also blank and don't look correct

I am having trouble loading the 512x pack on my mac. I can load the 256x one just fine, but the 512x one almost completely loads but then says "Resource reload failed." I am running MacOS Tahoe 26.6 Beta and have Silicon M3 and Metal GPU. I have logs if needed. It said stuff like "Caused by: net.minecraft.client.renderer.texture.StitcherException: Unable to fit: minecraft:block/weathered_copper_door_bottom - size: 512x512 - Maybe try a lower resolution resourcepack?" which (I think) means it had trouble creating the texture atlas. Thank you.

I get this error on MacBook M5 Pro.
Java 26.2
256x Java Pack

The 128x pack works fine however. Let me know if there's more info that's needed.

Right now the Map and the grass mod aren't downloadable through the 'extras' section of the Optimum Realism webpage. I took a look at it and it appears to be due to the fact that the download url and the user's tier isn't being passed to the "thanks" webpage so it has no clue where to find the download (and dlHref stays blank). Unfortunately the download URL for the maps goes go a patreon page that it says I don't have access to (possibly doesn't allow direct downloads, I don't know the workings of Patreon).
