I am so sure you already know this... but just in case;
Martin Mac Viper:
- shutter frame assembly rotate direction is reversed in Aug3D vs real life
- gobo rotation 'stop' values are incorrect in Aug3D vs real life, as are the general rotation speeds. Direction's correct, though... ;-)
This is all in the current release version, with Vipers in an older showfile but updated to that fixture library.
Thanks!
Rob.
