Textures glitching out randomly with a weird pattern

[maasj]

Anybody have any idea what this is? Its happening randomly to like 5% of the objects in every level. If I open the material there is a texture or two that is just blank. If I reload the texture from source it fixes it. Or if I restart the project it fixes it… but other textures will be missing…

Hello @maasj
It seems is because texture streaming is active:

Also take a look to the material:

[maasj]

Yea same here. Isn’t texture streaming necessary tho?

[alberto]

I did deactivate, in fact In the cinematic settings is not active

[capcaspa]

I deactivated texture streaming and still im getting glitched textures

[alberto]

Yeah @capcaspa but your system is dying
try this command according the ram you have assigned to the graphic card:

r.Streaming.PoolSize 20000

Also look the changes I did in the texture

Here another post about it:

[Screenshot_2] Try changin this value

Thanks @alberto
I made the adjustment and is working.

Now aplying the same to all the texture in my scene

Change multiple textures properties all at once: is it possible?

Hello, I want to change the properties of 15 textures (brightness) for the same value (from 1 to 2) I don’t want to open one texture at time and change the brightness 15 times! =( I want to select all textures and, if possible, change the properties all at once. Is it possible? Thanks!

Randomly i got a lot of materials with the glitch, if I resave the texture is fixed, doesnt matter what attribute I change

If i move far away from the objects the glitched texture appears

Yes you can by selecting them and then right button - asset actions - bulk edit properties

What is the size of the textures that are causing to glitch out? You might wanna try and optimize your texture resolution, that’s what I did to solve this issue for me. I had downloaded highest quality assets from Megascans, and that had 8k textures and I had a lot of those meshes in my scene. I lowered them to 4k and some to 2k as needed and the issue went away.

[capcaspa]

The textures that are glitching are 4k or 2K, and some are from megascans,

Happens totally at random

Is there any solution to this? Still happening, 5.1.1
12gig vram, 32gig ram, its a simple scene with onyl 12x2k textures, started happening randomly. Do I have to worry about losing a project and switch back to UE4? Any recommendation appreciated!

Still getting the error at random moments

The patern changes depending of the scale

@alberto @capcaspa @Whosdr @maasj Finally I figured its an issue with UE binaries partly translating to chinese (I know), issue happened to me and could always be fixed by reloading the asset, this problem happened more often when the texture pool was close to full, and also when using source control. But you can always reload it through asset action menu. Source control binaries mapping might be off, or texture pool can overflow and creation of mipmaps somehow corrupt.

Wait, unreal binaries from the epic launcher are partially in chinese? that’s what cause the texture glitch? Is there a fix for it?

I just came here to say I actually like the pants with that hatched, multi-grey pattern.

There is a piece of official documentation about how to set source control on perforce that explains up typemaps properly to prevent the problem, many techs seem to skip that step assuming its OS related. On the other hand if its a texture glitch due to low memory, seems like the only option is to reload through asset actions and let the shader recompile, and optimize and/or buy a new GPU.
