Shimmery, sparkly textures

Hello, I am new to this, and I am having problems with the textures and the multimedia player when passing it to the Oculus quest search, since when they are close they look perfect, but once I go away, they start to pixelated and strange glitters. I have been looking in oculus redering pages and I think k found the problem but they only give solution for the unit and could not fix it in unreal. Can anybody help me? I leave the link below
