Unable to invert matrix

Posted by Nico Jones on October 9, 2013 at 10:41 am

HI there,

I’ve seen this error posted about a couple of times, but none of the solutions are working for me…

I’m working in AE with some shape layers parented to nulls, parented to other nulls etc etc. I keep getting the following errors, not only when rendering, but also when working…

Cannot normalise zero-vector (17::52)
Unable to invert matrix (17::45)

It seems to happen when I switch to full quality preview, and then obviously when I render. Happening on a mac pro and macbook pro, latest CC and CS6.

I can only pin it down to parenting to shape layers. If I precomp the layer and don’t collapse the transformations, it’s ok, but that’s not really a solution as I need to use shape layers, and already built a load of stuff at quarter quality that would be a real pain to go back and convert to non-rastered shapes.

Any ideas??

Thanks,

nj

And now it’s happening at quarter res, and it’s deadline day, and this is grim, grim, grim.

Oh, and tried turning off new snapping feature. No dice.

Ok, turning all scale attributes from 0 to 0.1 seems to have solved it, as per this post I eventually found…

OK, now it’s happening when I try to rotate a null that stuff’s parented to. I’ll just resign myself to never parenting anything to anything until the next update. *update* – think I just hadn’t scaled some bits to 0.1…ignore my ramblings.

For others reading this:

This is a bug in the new snapping feature that causes a problem when any layer in the composition is scaled to 0%.

This is fixed in the After Effects CC (12.1) update, due out this month.

I’m getting this error still. 3d shape layers parented to 3d nulls that are scaling and rotating are fine — the shadow casting from a spotlight is triggering the error. Running Ae 12.2.
