Tycache, splines

[9877tteera]

Hi, I'm trying to export an animation in TyFlow and I can't manage it. I am a beginner and have made a simulation consisting of tysplines. When I export the tycache nothing appears, however when I enable "display as dots" I can see the dots. When I export the tycache (splines) the splines export, but when I open the file again they are without thickness - not visible on render (example in the attachment).... I have tried to work in many ways and I can't manage this problem, maybe you can tell me what I am doing wrong?
I am using BETA v0.16134.

In your screencap I don't see a tySplineMesher modifier on the splines, so that's why they don't have any thickness (ie, a mesh).

When the Export Particles auto-creates a tyCache object for you after export, it adds that modifier. So it seems like it was accidentally removed, or you created the tyCache from scratch and forgot to add it.
