Hi folks. I have the same issue in UE5 Beta - so I am assuming that it is also a problem still in 4.27. My problem was that some paint surfaces would flicker when the object was rotated. This is specifically for the Paint material - eg M_CarPaint_Master.
My solution was to modify the master material keeping the majority of the orange peel effect, but just simply skipping the tri-planar modifications that affect the orange peel. TBH I am not sure what tri-planar is doing in this case, but in my situation it is visually OK without tri-planar additions.
Images with and without the Orange Peel (as set in the material instance) - using the modified solution. Without the orange peel it just does’nt look right to me.
