I repro on 2015. Did you test on an SP? Your workaround is a valid one since MR is doing that under the hood anyway. Don’t know if much can be done at this point; However, it’s imo it’s rare to use deformers on nurbs. I’ll check if it’s logged.

Maybe it's not a fatal error, but a schoolboy error!? Anyway, I converted the object to a polymesh and it's fine now. Not ideal but it works.

I'm doing some shape animation on the lattice, but when I render a sequence, I get a Mental Ray fatal error after it completes rendering frame 1. I've remade the lattice animation on a new lattice, but I get the same error. If I delete the lattice, it renders ok. So it looks like an issue with nurbs/lattices/shape animation. Is this a known problem? Any thoughts/workarounds?
