Here is the extra info Fabrice, thanks for your time….
The material of this model is using textures from ATF sprite-sheet.
Lights are baked and are being used from the same-sprite sheet.
Far value for camera is 8000.
The blurry look is a pre-blurred image on the sprite-sheet added to an additional model that is slightly bigger than the one that holds background texture.(nothing fancy going on there)
Important is to explain that the model with the blurred texture is actually rotating, but the artifacts are fixed on their position. AND every time that the game is opened they appear in a different place.
This also occurs ONLY on SOME Windows computers until now and no error is being dispatched.
PD: I have checked out the commit: “21e90e57121f02a0a6820349c93fa94806454073” tagged as “v4.1.5”
