I don't know if it's any of my mods or shaders, but it simply removes the texture from them, leaving just a solid color. They still have their traits, like the slots for the crafter and the glass from the tanks. Casings suffer from the same bug. Also, mechanical belts just leave a huge gap, and the only part of the belt that appears is the one that is touching the shaft. For example, i want to make a 5 block long conveyor, but it just creates a belt for the end of the belt. Trying to stand on the gap tries to teleport me out of it's hitbox. Destroying the belt from the end still creates break particles. Placing shafts for every empty space makes it not move, but it is needed to cut the rotational force then connect it again to make it move again. Standing on the belt makes my character slip on it.
Here's my debug log.

Maybe i did not update forge.

Have you checked out the Troubleshooting page already?

And the shafts?

Can you post your modlist?

This could be an OptiFine compatibility issue. Try removing it and see if the issue persists.

Also try a newer version of OptiFine.

I am using TLauncher. Installing manually versions breaks my game. Optifine worked fine for me some days ago.
Here is a video.

My optifine is up to date.
Either is forge.

Please rerecord the video while the world is in daylight. I can't see a thing.

As I said, try removing OptiFine and see if that fixes the issue.

Disabling anisotropic filtering and/or antialiasing in Optifine's quality settings should fix the issue.

optifine changes lots of code in base game, requiring other mods devs to adjust their mods to make it work with optifine. it would be easy to fix, if optifine were open-source, but it isn't, and it's license doesn't allow you to use decompiled optifine code in your publically available software, IIRC

also, for me, personally, optifine causes more troubles than it fixes, making it no-no for me, even when i play vanilla

Why would Optifine cause that?

I also, HAVE DISABLED IT AND IT D I D N O T W O R K.

I don't want to remove Optifine. It worked normally until this happened.

Every computer is diffrent, especially when it comes to graphics, computers use diffrent GPUs and could affect outcome.

Man, i said it was one of my mods.

But i don't know which.

Apparently, OptiFine was not the cause, i told you all.

What is? Would be nice info to know.

And we suggested Optifine as the issue since it was the most common cause of the texture issue, though there could be some expections.

Apparently, OptiFine was not the cause, i told you all.

It is important to rule out all possible causes, even if you think that they are not the problem. It is a natural and important part of bug testing and fixing. Knowing it is definitively not optifine is very helpful as it rules out something and narrows down the actual problem.

Well, you have my mod list. You should know what causes that.

It was failing after i installed some of the Better Minecraft mods.
