Hi all,

Experiencing an issue where I am placing a model down in a room with some tables. At first, the floor’s surface is correctly detected, and the model is placed on the floor as desired. After a few movements / camera shakes, however, a new surface detection takes place and the tables become the new plane on which the object rests. Is there any way I can prevent this, or limit the amount of surface redetection that takes place in my experience?

Thanks 🙂

- Nicholas

Hi @Nicholas_D_Agosto,

8th Wall’s engine works a bit differently than you may be used to working with ARKit/ARCore in the past. Essentially your scene is a single planar surface (Y=0) that is anchored to the primary surface in the space around you (floor, table, etc). If you move around, things can “shift” / “jump”

Here is a video that illustrates my point here:
