Convert Color Float to Script Vector

[TubeSmokeGuy]

Don't know if this is helpful, but with Krakatoa and its Magma modifier you can redirect the color channel into MXSVector. See screenshot attached.

In the particle data viewer utility the the MXSVector seems to be stored correctly as it has stored the colorvalues after the magma modifier.
And with Krakatoa partitioning saving particles to disk you can add the MXSVector natively from the channels list (left side of the screenshot).
