Helo,
I did recently as follows:
I created a show rig setup in Spotlight. Just fixtures in correct positions, some truss and flybars. Then I exported MVR to my GrandMA3 showfile and merged it into my file. Then I did the patch inside MA3 software, assigned correct GDTF libraries, adjusted Layering and Classing a bit and exported MVR from GMA3. I imported this adjusted MVR file into original *.vwx file. I hoped for updating information in already existing set-up, so already present fixtures get patch information, etc., but there just appeared new set of fixtures upon original ones, they all fell into one layer ignoring sorting made inside GMA and they do not have correct geometry. Is there some major wrongdoing on my side?
Thanks.
