   Combine Bakes

   Pack all source points.

3. 3
   Sample Count

   The sum of the source counts.

Combining preserves positions and weights and interleaves banks proportionally. It does not relax spacing or remove duplicates between banks. Overlapping regions remain denser. Source assets are unchanged.

Maximum combined bank: 1,048,320 points. Self references, duplicate sources, stale sources and cycles are rejected. The destination’s Sample Bank Size does not choose the combined count.
