Hey Pilou,

have you considered using or seeing if the MOI Ai export instead of svg can work direct in your tool...

script: /* Copy AI format to clipboard */ moi.geometryDatabase.copyToClipboardAI();

maybe then you have less files to save, a more direct workflow
just moi-copy, paste, render your 'svg' animation?

edit: i also think moi might save svg to clipboard...
script: moi.geometryDatabase.copyToClipboardSVG();

cheers

Stefano
