When you create a placement while also having optifine loaded, the mod goes crazy and the schematic isnt usable anymore

I'm now using:

Fabric 0.11.6
OptiFine_1.16.5_HD_U_G6.jar
optifabric-1.9.2.jar
litematica-fabric-1.16.3-0.0.0-dev.20200913.215807.jar

(Used it with both curseforge and multiMC)

If the game is launched with no shaders enabled, and then enable the shaders once the game is running, litematica renders decently (you can see the blocks but they glow).

But if the game is launched with shaders on, the rendering is completely broken looking like random textures smeared all over and triangles. Not legible, cannot tell what the blocks are.

Disabling shaders won't help until the game is relaunched. Since it works if the game is launched without shaders enabled, I wonder if it would be possible to make litematica and optifine/optifabrick to play nice?

@Nopotato This was fixed in Litematica already back in January for 1.16.x. But you are still using a version from September 2020. Get the latest 1.16.5 version from here: https://masa.dy.fi/mcmods/client_mods/ (or even the 1.16.4 version from CurseForge, but that latest 1.16.5 build has tons of other improvements and fixes as well).

@maruohon Wow, that's awesome! I had tried to update my custom modpack but kept running into issues so i rolled back to an older instance until I had a combo that worked though I am prone to user error. Either way this one you linked me now works on my quick 1 minute test so I am very happy.

===================================
Litematica renders weird triangles, how to fix?

• Disable shaders in Optifine, and then restart the game.
• You may need to disable Render Regions and Fast Render as well to fix other rendering issues.

so litematica and shaders hate each other?

What optifine does i believe

I dont think litematica was ever deisgned to be compatible with optifine.
Try sodium or canvas instead and they dont break the litematica rendering.

I use frabrick, optifabric, litematica with 1.16.3, and sometimes it works fine and beautifully with shaders on, and other times it doesn't work at all. I have tried disabling render regions and fast render, but have not been able to get it to work again. I am not sure what causes the rendering issues, seeing as sometimes it just works fine.

Shaders disabled and restarted the game? @Nopotato

Shaders disabled and restarted the game? @Nopotato

Yes, disabling the shaders and restarting does not work, although sometimes (maybe 2/10 attempts) it does work, unless it was just a coincidence. For now I have chosen to remove the optifine set, to use litematica.
