Description

Sphere collision with start and end points set to the same value return no hit objects.

Workaround

Set the end vector to 1 away from the start vector (0,0,0 to 1,1,1, etc.)

Regression (no) issue (does) occur in 4.11.2

Steps to Reproduce
  1. Open Editor (any project)
  2. Create new blueprint (actor)
  3. In Event Graph>Event Tick>MultisphereTracebyChannel (Radius 1000)>OutHit>Length>To String>Print String
    (See image for additional clarification)
  4. Compile
  5. Place asset in level
  6. Ensure asset is in location where actors can be overlapped (within 1000 uu of another object with visibility set to block/overlap)
  7. PIE

Results

Print string prints 0

Expected

Print string prints length of output array, which increases by one for each actor overlapped.
