Although my problem is solved I still think it's an exporter bug.

Thanks

This is a precision problem. The numbers representing the vertex positions are too small to be represented exactly. Maya uses 64-bit floating point numbers for positions, which still offer good precision at that small scale, but Maxwell uses 32-bit precision because it is the most efficient format both speed-wise and memory-wise. This is why the object looks fine in the Maya viewport, but it's broken when rendered. It's not something we can fix without slowing down the engine.

Yes, but Fire works fine. Can the exporter handle that special case and propagate the scaling to group objects?

FIRE and the main render use different code for voxelization, so maybe that's why FIRE is less affected by precision issues in this particular case. Anyway, I'll take a closer look to make sure precision is indeed the culprit here.
