Suddenly Static Mesh Flickering

Development Rendering

Hi there,

im currently testing unreal studio and working on big interactive siteplan. I recently updated the model trough unreal studio and now got flickering when the camera is far away from the scene. The ground level is perfectly fine.

You can see clearly a border, on which the flickering is starting. (04.png) The planes on the ground have all 5cm distance.

What could be the problem?

Best regards,

That is what i thought too. When i change the height difference of the ground planes to a higher value (10-20cm) the flickering disappears. BUT - before the model update everything worked fine and with the update only 2 buildings changed - not the ground planes.
