Whilst in turret/gunner view of a UAV, placed user textures 'User Texture (10m)' aka 'UserTexture10m_F' will display either below, between or above an object in relation to the current altitude of said UAV.
User Texture Below.
User Texture Partially Through (Low).
User Texture Partially Through (High).
User Texture Above.
As you can see, a user texture that is placed below an object on the terrain (ATL) will change layering in relation to the height of the UAV (camera), which causes the user texture to show (bleed through) incorrectly.
