Your road marking is to close to the mesh of the street. Here you will find a solution: A photo is not rendered fully
Hello, I can’t solve this problem by modifying z-offset.The texture keeps flickering when the camera is turned.
You have to adjust the position of the faces in your 3D model. There is the road (two big gray faces) and then there are the lines (orang and white). Move the orange and white a bit up (Y axis, or Z axis in Blender) so they’re above the gray (road) faces. You should do it in your 3D software. Reexport the model and it should be OK.
