Render sequence ground texture issue/flicker

Hello,

I am a newbie in UE trying to learn the workflows with megascans textures and I have ran into an issue when I try to do a test render of my simple scene and camera animation, the ground (simple plane imported as obj) texture flickers during render and does not render correctly at all.

Please see this video showing the issue: https://youtu.be/XUHyB4RYR_E
Any idea as to what could be causing this problem?

Thanks

Have you find the answer to your problem?

I have the same problem in 4.20

Thx
