Hi,

RBD Bullet sim produced few pieces with what seems like Euler discontinuities.

I convert @orient to @rot and try to fix it in CHOPs with Euler Rotation Filer, but it has no effect.
What am I missing?

Thanks

thanks for hints. Please take a look at my example file, rx ry rz are not consistent, plenty of flips.

Surely RBD sim looks good, but its hard to work with such data when doing post sim orient blending to another values. I believe if rotation data was consistent I wouldn't have any issues.

Still, Euler Filter should work...

Thanks

oh matrix, my bad. Neo wouldn't be happy about that.

Thanks a lot! All good now
