I'm having a bit of a problem as I have a bunch of small animations that need to be exported in FBX format, however many of them have Spline Masks which cannot be exported in this format. So, my question is - is there a way to bake a spline mask? I've tried the Nitobake and Steadybake plugins but have not had any luck so far. Could Xpresso be the answer? I've tried but failed to create a spline that replicates the Spline Mask inside Xpresso but my knowledge in that area needs some sharpening.
I've included a c4d file that shows an example of the kind that I'd like to export in FBX format.
Unfortunately it seems Alembic only exports polygons, and I was working purely in splines. Bit of a bummer. However, I've just discovered Bodymovin https://github.com/bodymovin/bodymovin which allows you to export AE shape layers as JSON files which is perfect for my needs as I was porting everything over to MaxMSP.
