Flame shape data only outputs 1 shape?

I’m testing out Mocha Pro and it seems to only output a single shape with Flame format.
The other shape output formats support multiple shapes.
Why is this?

Usually limited exports are issues with translation from one program to another. I can ask the dev team why this is so, but right now, that is the workaround we have.

One of the retailers got in contact with Mary and got this answered:
Mocha cannot currently export multiple spline-based shapes to Flame, but Mary from Imagineer (CCed here) says you can export multiple shapes as a rendered matte for Flame:
file > export rendered shape
choose: selected, all visible, or all

Seems odd, that Flame is limited in this way.
