VR Expansion Plugin

Hi, I’m using this plugin and the template in a project for Meta Quest 2 using some marketplace materials with parallax occlusion mapping (edited to work on mobile using a solution found in this forum), and I’m noticing that if I get too close to some meshes using parallax (walls from Medieval Dungeon pack) they fade away proportionally to the distance from the player, but not entirely (there remains some “tears” of wall).

I found that parallax can work on Quest 2 standalone in a starter UE5 VR template project, but how can I make it work on VRExpantion template as well?
