Build wall with megascan and cube shape, but need more polygons for tesselation to show correctly

Here is a styp by step guide:

  1. If you didn’t activate tessellation in your material, activate it!
  2. If tessellation factor of 15 (engine max) is not enough, modify the shader files!
    I use tessellation factor 64 with distance-based tessellation.
  3. If you still need more triangles, combine a plane with high tessellation with the high tessellation material.
