Engine Crash Pointing to a Texture

[Maximum-Dev]

Hello,

For some PCs engine crashes while trying to load a map. The error is pointing to a texture and I’m having a hard time finding the cause.

It’s a splat map used on a landscape.

8192x8192 Res
Masks compression
No mipmaps

We’ve had lots of textures like that in different projects and it’s the first time this is happening.

Level loads fine on some PCs, but on others:

Would gladly appreciate any help.

Hello, we seem to have similar problem. Also only on some of the PCs. Did you find any solution?

I’m also getting this issue, anything from Epic Games?
