An example with a projected spiral:








It only guarantees the spacing of each instance from the one behind it along the curve though, if your curve comes too close together in different areas then the items between those areas can still get bunched up to one another.

But at least this avoids bunching of adjacent items along the curve though, which could be hard to avoid with the regular kind of curve array function that measures distance as traveled along the curve rather than the direct 3D distance between things like this new one.
