Someone, a long time ago, told me that happens when you attach something that is too high poly. Not sure how correct it is, but that is the first thing that comes to memory.
Finished the dashcam, made a new console and added the Toughbook model I made 2 years ago, yet never used it. The generic login screen texture is not final, I'm still looking for better ideas.
I made a custom MDT screen for myself a couple of weeks ago. If you want I could send it to you, just PM me on Discord, Slendis#0001.
