tySplineMesher memory use

[tyFlow]

By default, tySplines objects internally cache all data in order to play back faster. You can disable this behavior in their settings. Note: if you're not rendering frames sequentially from the start, you'll need to disable caching in your tyFlow object as well in order to keep tySplines and tyFlow synced if tySplines caching is disabled.

The easier solution is to just cache your tySplines to tyCache using an Export Particles operator in 'splines' mode.
