Strange Orange Glitch [SOLVED]

[domdiogo75]

Hello, friends

 

Recently, after many years of playing a heavily modded game, I have experienced this strange phenomenon: When I turn my character at certain angles, textures (or shadows?) in specific areas momentarily turn orange, as pictured below. Does anyone have any clues to help me solve this?

 

Thank you!

I don't know what game your screen is from but, have you tried rearranging any mods you suspect may be in conflict in your load order? You said you had a heavily modded game. I'd take a long hard look at that load order. But if it's not that, I don't know. Is that how that game normally displays conflicts with meshes/textures? With Morrowind, it's all pink if there's no texture and a big yellow triangle when the game can't find a mesh.

Sorry, my game is Oblivion. In all this years I never saw anything like that.
As you said, missing textures or meshes show constant evidence, but this, this happens only in specific angles, in specific areas.

I have to ask, has anything recently changed about the way you play the game? Have you updated your OS or graphics driver? Anything that could be relative. I would go ask around in the Oblivion forum or maybe the Hardware and Software section.

Cheers, hope you figure it out.

It is exactly what @UsernameWithA9says. It is not a mod but the default game shader. Oblivion probes your hardware and tries to determine what you've got, then selects the most suitable shader which is like a graphics driver, a fundamental thing. They are found in Data\Shaders folder.

Now, if your hardware or driver is newer than Oblivion, which is likely seeing how the game is 18 years old, then Oblivion cannot read your hardware and picks a default shader which is likely the wrong choice. It goes particularly bad on AMD-based hardware.

In any case, there is a solution. There should be a text file Render.txt in your Oblivion folder - that's what Oblivion was able to read about your hardware. In there it says which shader it decided to use (they are numbered). This is the file name it will stick to, so in order to make the game use a different shader, you need to copy and rename one of the other ones. Make sure to make a backup! Using the wrong shader may prevent your game from starting or give you glitches much worse than orange blobs.

There is more and better information about it on the internet, but I lost the link, so you'll need to look around.

Hmm, I'll have to keep an eye out for that next time I play, being on an AMD card.  Though so far I haven't noticed any issues in my limited testing, running in Steam Proton on Linux.

You will have different drivers on Linux. It seems to be a combination of several hardware and software components that determines the result. Nothing is guaranteed in Oblivion, not even glitches.

Indeed, different drivers, plus Wine and Proton's "translations" of the shaders from DirectX or OpenGL to Vulkan. 

(Most of my games, Steam downloads a lot of this shader stuff pre-cached, so Proton doesn't have to make it on the fly.  And there are continual improvements, given how often it downloads more of these for my more graphically-intensive games.)

Thank you for answer. I am using Oblivion EGL (Vulkan), in this case, your suggested solutiion may work? And yes, I have AMD-based hardware, CPU and GPU.

Thank you, everyone! Problem solved. In EGL options I changed settings in "Curves.fx" shader and that glitch is gone.
