Hi Evgeniy!
- Yep the bucket numbers are fine here. The index relates to this Enum located in SpatialAccelerationCollection.h - 4 are named with 4 able to be used for custom things[Image Removed]
Buckets wise, 0 relates to the static objects while 1 relates to the dynamic elements looking at the debugger output
2.+ 3. I’ll take a deeper look into these and get back to you. Initially 2 looks like that will mean the objects are all in leaves, but not a hierarchy.
