Same as SG, I could not implement the explanations on SG's file, in order ot see the MU's (in lower level frame) on a machine defined in an upper frame.
I appreciate if you can complete SG's file.
here you go.
I´ve updated your model to work ( s. attachment).
What I noticed, was :
- 3d objects in the machine frame were completely switched off (no link to 2d)
- you created animation paths directly in the machine frame, hoping the Mus would move on them, which they won' t, as they are dedicated to the 2d-objects (which were switched off).
Just to show you, how it works, I´ve switched off the station graphics in the machine frame
If I got it right , the graphics in the frame111 are switched off. select the appropriate 3D-node (machine or frame111) press cntrl 3, select tab "visibility" and switch on "visibility content"
