Help Need the positions to drive VFX graph

[spikebor]

In Obi 7, the solver.life array contains particle remaining lifetime (in seconds). You can access these just like you access positions.

The functionality is perfect, with my terrible writing skill (I release and rewrite the pos and life Buffer everyframe(!?)) yet it still looks like it does not take any performance hit!
Almost feel like magic. Let me know if you want to look into this setup and perfect the function into something to ship with ObiFluid, I name this ObiVFXRenderer.
