I am facing the following problem: I am using a Vuforia Planefinder and Ground Plane Stage in order to place 3D objects in the scene. There is a terrain and meshes on that terrain all parented under the Ground Plane Stage. It works to place them in AR and when deployed to Android everything seems to work fine so far. But when moving around after a short time it often happens, that the terrain is jumping out of place and is slightly offseted to the other GameObjects (Meshes). On IOS it seems to be even worse. There the terrain is completly out of place directly after setting the target in the environment. I have searched the internet and found people facing similar problems with image targets and unity terrains. But none of the provided solutions helped me. The terrain is a direct child of the Ground Plane Stage like the other game objects too and the "Static" option is disabled on the terrain.
Is this still a known issue when dealing with unity terrains in Vuforia or is there any other possible solution that could help?
Thanks in advance!
