Hi...
Apologies for the confusion. The tutorial you link to was created during development of iClone 8 when Smart Gallery was still being used.
However, as I mentioned previously, now in iClone 8 the Smart Gallery Plug-in is no longer used and the features of Smart Gallery are built into Content Manager. There is no separate plug-in to install.
Regarding the motions used in the tutorial, the walk motion used up to 1:31 is from the City Life motion pack. Unless you have purchased this pack you won't have access to these motions. Of course you can use other motions instead of the exact ones shown as the tutorial. The purpose of the tutorial is to show how to do basic motion editing so the motions being used do not need to be exactly the same.
