What kind of mesh are you applying it to? Specifically the one that is flashing, but since one is flashing and the other isn’t, are they both the same mesh?. Did you import that mesh, or is it just the plane actor from the starter content? If it was imported let us know how many polys make up the mesh, and if it’s not just a single quad post an image of it in the mesh editor with wireframe enabled. Lastly check and make sure your material and mesh are not set to 2 sided. For the material the setting is in the details panel shown above, for the mesh you can find it under the Build Settings menu in the mesh editor window ---

Thanks for your reply. Both are flashing but in those gifs only is doing one of them, in one gif because I had select it, and in the other because It doesn’t flash if I’m looking directly on it. I tried with unreal plane mesh and an imported plane mesh with 10x10 (200tris) polygons from Maya. I tried with “displacement” and “world position offset” and I got the same result (or similar). ![](https://d3kjluh73b9h9o.cloudfront.net/original/4X/7/e/f/7ef825a4d80eae4a72628f99f81f0eee9eae7fb1.png) ![](https://d3kjluh73b9h9o.cloudfront.net/original/4X/c/4/f/c4f9476133a252756bc7abed762b3b991f7cf7c6.png) ![](https://d3kjluh73b9h9o.cloudfront.net/original/4X/b/3/8/b389ef3ba9a3d280a2a178bed86761b6d5f9f7e2.png) Oh, and the material is not 2 sided. (Anyway tried if it works with 2 sided) ---

Thank you very much! It work perfectly now.
