why vrayscene export with yeti cache take so much time?

Export to a .vrscene file
in scene only 6 yeti nodes with link to cache.
display output disabled
show in viewport - none
in result 108 Kb vrscene, in it text only link to yeti cache files.
Why export take about 1 min per frame?

I’m not really sure. Is it possible to get us a scene to support@chaosgroup.com so that we can check? It might also be useful to ask on the Yeti forum.

Best regards,
Vlado
