Spatial Understanding Queries Return Empty Array
Does anyone have the issue of spatial understanding queries returning a null array. This happens with the topology query and the shape query. I want to place objects randomly on the floor, and I know it identifies the floor correctly (I print the values of the scan during gameplay). I also know it stores the values correctly because I've had it read numFloors from UnderstandingDLL.GetStaticPlayspaceStats() to me immediately before the query, and it's a nonzero value. However, it never places my objects because the return value of the query (which is supposed to return the number of matches found) is always zero. At this point, my code is copied from SpatialVisualizer.cs.
Is this a common problem? Any known fixes?
I can provide my code, if needed. In case it matters, I'm on Unity 5.5 and I'm working with a HoloToolkit from February.
Thank you so much!
